Abstract:

Technical debt is used to describe the changing or to maintain a system due to expedient shortcuts done during its development. In the context of the software development industry, technical debt is regarded as a critical issue in terms of the negative consequences such as increased software development cost, low product quality, decreased maintainability, and slowed progress to the long-term success of developing software. Code Smells are well informed in the domain of Technical Debt. They indicate to the common bad practices that may impair the future quality of the software system. By identifying those Code Smells, it is possible to give an improved solution or make the developers aware of a possible deficiency. I explore the premise that technical debt within the enterprise should be viewed as a tool. Extensible and Appropriate tools can check the Code Smells automatically and improve the quality assessment accordingly. However, in the field of Enterprise Architecture(EA), common bad habits in EA can be called EA Smells. EA Smells itself can be a component of EA Debt. Enterprise Architecture Debt can be defined as such a metric that depicts the deviation of the currently present state of an enterprise from a hypothetical ideal state.In this thesis, we introduce SmellCull as an extensible tool for capturing, tracking and managing Enterprise Architecture debt in the EA field. SmellCull allows measuring different kinds of Enterprise Architecture debts for EA Model. SmellCull is extensible since different types of Model can be integrated as input into the tool environment and provides developers with a lightweight tool to capture EA debt and make it easier to understand them indicating corresponding parts in the implementation. The tool is used to create propagation paths for the EA debt. This allows for an up-to-date and accurate presentation of EA debt to be upheld, which enables developer conducted implementation-level micromanagement as well as higher-level debt management.Since the tool is sophisticated enough, automated detection supports the design process and ongoing change of EAS(Enterprise Architecture System). This includes the strategic development of EAS with the corresponding roadmaps, as well as design assurance and performance monitoring to assess the quality of data in EA repositories and the compliance with certain standards defined by EA Smells. Due to the limited scope of master thesis, the tool will identify a few number of EA debt. At the end, some future work suggestions in the context of identifying more salable Enterprise Architecture Debts with this tool are given.
Teknisk skuld dvs dålig eller kortsiktig programutveckling som belastning på IT-system måste förr eller senare återbetalas. I industrin betraktas teknisk skuld som en kritisk fråga när det gäller de negativa konsekvenserna som ökad mjukvaruutvecklingskostnad, låg produktkvalitet, minska underhåll och långsammare framsteg till den långsiktiga framgången med att utveckla programvara. Dålig kodkvalitet “code smell” är vanligt förekommande teknisk skuld. Det uppkommer i vanliga dåliga metoder “anti-patterns” som försämrar programvarans framtida kvalitet. För att kunna identifiera bristande kodkvalitet är det möjligt att skapa en förbättrad lösning eller göra utvecklare medvetna om de möjliga bristerna. Jag undersöker förutsättningarna att en sådan teknisk skuld i företag bör undersökas med en programvara. Utbyggbara och ändamålsenliga programvaror kan analysera källkod och hitta var kvaliteten behöver förbättras. Företagens tekniska skuld kan definieras som ett mått som visar avvikelsen från ett hypotetiskt idealtillstånd genom att jämföra det aktuella tillståndet med praktiska rekommendationer “best practice”. I detta examensarbete introducerar jag SmellCull som ett utbyggbart verktyg för att hitta, spåra och hantera bristfällig kodkvalitet inom företagsarkitektur (EA). SmellCull tillåter mätning av olika typer av tekiska skulder för EA modellen. SmellCull är utbyggbart genom att olika typer av datamodeller kan integreras som indata i miljön, och det ger utveck-lare ett lätt verktyg för att hantera teknisk skuld i programmeringsprojekt och hjälpa projektdeltagarna i programmeringsprojekt att förstå vad orsakar brister i kodkvalitet. Eftersom verktyget är tillräckligt sofistikerat finns det automatiserad spårning, designprocess och kontinuerlig förbättring av EAS (Enterprise Architecture System). Detta inkluderar strategisk utveckling av EAS med motsvarande färdplan, samt konstruktionssäkerhet och prestandäovervakning för att bedöma kvaliteten på data i EA förvar och efterlevnaden av vissa standarder som definieras av EA code smell detection. På grund av den begränsade omfattningen av examensarbetet kommer verktyget att identifiera några få EA skuld. I slutet, några framtida arbetsförslag i samband med identifiering mer säljbara företagsarkitekturskulder med detta verktyg ges.

The demand for Saudi oil is increasing locally and internationally, and being one of the major oil exporters in the world, the government of Saudi Arabia needs to balance between local consumption and international demand. To address this challenge, Saudi Arabia is adopting an aggressive strategy to use solar energy instead of oil to generate electricity. This strategy creates an opportunity to diversify the country's GDP by building solar manufacturing industry. This thesis uses the Enterprise Architecture Framework, developed by Nightingale and Rhodes, to propose the optimal architecture for the Saudi solar manufacturing in terms of organization, policy, strategy, product, services, infrastructure, and R&D. The first stage of the framework identifies the landscape and the major stakeholders in the solar manufacturing, and then studies the current situation of the Saudi solar manufacturing. The second stage analyzes the different proposed architectures. The third stage evaluates the different architectures, and the fourth stage selects and validates the winning architectures. The evaluation criteria for the different proposed architectures are based on three angles: "Attractiveness", which measures the level of compatibility between the architecture and the needs of the Saudi government. The "Effort", measures the human and financial effort required to deploy the architecture. The "Risk", which measures the different risks associated with the architecture. The winning architecture encourages Saudi businessmen to acquire international companies along with building local manufacturing for products in the lower end of the solar manufacturing value chain. The strategy in this architecture is to build fast capabilities in the technology and process side by acquiring international companies and steady capabilities in the production side by gradually moving up in the value chain. Also, the architecture proposes focusing and building the local R&D capabilities to improve the productivity, and profitability of the solar manufacturing companies.

The need to relate the various architectural domains captured in partial descriptions of an enterprise is addressed in virtually all enterprise modeling approaches. One of these domains, namely that of organizational behavior, has received significant attention in recent years in the context of business process modeling and management. Another important domain, that of organizational structure is strongly inter-related with the process domain. While the process domain focuses on how the business process activities are structured and performed, the organizational structure domain focuses on who performs these activities, i.e., which kinds of entities in an organization are capable of performing work. Given the strong connection between the organizational behavior and organizational resources, we argue that any comprehensive enterprise modeling technique should explicitly establish the relations between the modeling elements that represent organizational behavior, called here behavioral elements, and those used to represent the organizational resources (organizational actors) involved in these activities, called here active structure elements. Despite the importance of the relations between these architectural domains, many of the current enterprise architecture and business process modeling approaches lack support for the expressiveness of a number of important active structure allocation scenarios. This work aims to overcome these limitations by proposing a framework for active structure assignment that can be applied to enterprise architecture and business process modeling approaches. This framework enriches the expressiveness of existing techniques and supports the definition of precise active structure assignments. It is designed such that it should be applicable to a number of enterprise architecture and business process modeling languages, i.e., one should be able to use and apply different (enterprise and business process) modeling languages to the framework with minor changes.

Abstract:

The U.S. federal government spends millions of taxpayer dollars to implement the federal enterprise architecture framework (FEAF). This qualitative multiple case study extracted successful FEAF implementation strategies used by agencies in the Washington, DC, metropolitan area. The population for this study included 10 information technology (IT) planners in 3 federal agencies. Data were collected from semistructured interviews and triangulated in comparison to 33 public documents. General system theory was used as a conceptual framework for the study, and data analysis included reviews of the academic literature, thematic analysis, and member checking to identify themes and codes related to successful aspects of the strategies collected. Key themes emerging from data analysis included critical leadership support for implementation, organizational culture, practices for maintaining an accurate organizational history, and means to maintain this knowledge. Based on the findings, the implications of this study for positive social change include efficient, effective, and reliable government services for U.S. citizens and a significant reduction in IT spending in federal agencies. In turn, the results may result in effective federal services and effective use of taxpayer money.

Abstract:

Digital transformation has been a focus of public and private sectors to both improve and sustain business value by leveraging rapidly evolving technology. Digital technology is ubiquitous and inter-connected, changing the face of business, government and society through the creation of new industries, with automation replacing two thirds of existing jobs. The challenge is that most digital transformation efforts fail, mainly due to inadequate leadership and management as well as failure to accept that it is a multi-disciplinary problem. Another challenge is to distinguish between digital transformation (DT) and digitization where the former is based on a customer-centric value proposition and the latter focuses on cost-cutting and operational excellence. This difference also highlights the business/technology divide where the former is mainly DT and the latter is mainly digitization. The challenge addressed in this thesis is how to obtain management acceptance that digital transformation is multi-disciplinary and to make recommendations with respect to how best to achieve DT goals. The research methods followed is a blend of participatory action research (PAR), case study analysis and literature analysis. The principal research findings are that there is no single, management methodology that can increase the chances of DT success but that a modified form of enterprise architecture (EA) that collaboratively interacts with the other management frameworks can likely provide a solid foundation to effectively achieve DT. The thesis consists of an assessment of the current methodologies, four articles that each discuss an area to support effective DT, followed by a request for change (RFC) to up-date the TOGAF 9 EA framework standard. TOGAF was selected due to its pervasive usage globally (80% of Fortune 50 and 60% of Fortune 500). The RFC accommodated both the concepts raised in the articles and other innovations highlighted in the literature review and assessment. The thesis concludes that enterprise architecture is a key business technique that al-lows the sharing of core decision support information across the enterprise, enabling all management frameworks, especially those on the technology-management divide, to collaboratively realize digital transformation.

Abstract:

Enterprise architecture (EA) has gained increasing dominance in organisations as a strategic enabler to manage complexity. However, most organisations are still finding it challenging to materialise the full benefits of EA. Instead, literature reported that most organisations either failed to institutionalise EA or have caused additional complexities due to architecture decisions being disconnected from the broader strategic context. This highlights a need for investigating the root causes of the key challenges and finding ways to improve EA decision-making at the strategic level. In response, this thesis proposes a shift in focus for strategic EA decision-making. It provides a review of literatures, and a qualitative analysis of the points of view of key EA decision-makers and business executives. The findings were collected from the two of the largest South African retail banks. In-depth interviews were conducted with the key EA decision-makers and the business executives with whom they usually work. Insights were drawn to compare the views on strategic EA decision-making, forming the viewpoints and value propositions of EA service providers and EA customers respectively. This thesis takes the view that the customers, experiences and value co-creation should be the fundamental focus of strategic EA decision-making. This thesis starts by establishing the strategic role of EA in a typical organisational context. It enables organisations to be highly flexible with reduced level of complexity. However, the current EA institutionalisation is still littered with challenges. The thesis then presents service-dominant (S-D) logic as an alternative lens to examine the current business-EA relationship in strategic EA decision-making. Challenges in the current business-EA relationship are then examined to understand the various points of view and specific aspects that caused the disconnect between business and EA. This thesis analyses each specific aspect and establishes that they are largely ineffective and are grounded in goods-dominant (G-D) logic. Finally, based on the adapted premises of S-D logic, this thesis develops an initial conceptual framework that provides a set of guiding principles to address the business-EA disconnect in EA decision-making.

Abstract:

Enterprise architecture is the high-level design of the entire business, facilitated by enterprise architects. "Agile enterprise architecture" is the term used in enterprise architecture to describe an architecture that caters for future unknowns, enabling change to occur rapidly without undue resource utilization, yet in a controlled manner and with minimal adverse impact. Some enterprise architects still use outdated, rigid approaches to enterprise architecture which are incompatible with today‟s business environment. In addition, there is limited research into methods that can be applied to measure the agility of enterprise architecture. The current environment is such that there is a need for a more agile approach to developing and measuring enterprise architecture. This work will lead to the creation of a Framework for The Development and Measurement of Agile Enterprise Architecture. In support of the main goal of the development of the framework, a literature review will be conducted focusing on the necessary sub-goals of the research. The first sub-goal of the literature review is to develop a comprehensive definition for enterprise architecture (referred to as EA), as well as discover how it is currently practiced. Thereafter, the literature review will investigate a comprehensive definition for agility and research why it is emerging as a critical topic. The next chapter of the literature review will research how agility fits within the context of EA, uncovering a comprehensive definition for agile EA and the best practices in agile EA development. The final chapter of the literature review will investigate suitable measurement techniques that can be used to assess the level of agility of EA. On completion of the literature review, a preliminary framework will be created using the most important contributions from the literature. An empirical study will be conducted to explore the definitions for EA, agility, agile EA, the methods to measure the agility of EA and the concepts for the development of agile EA summarised in the preliminary framework. Data analysis follows an interpretive and qualitative approach based on four case studies through interviews with systems experts in four South African organizations in one province. Each interviewee was interviewed once. The initial interview with a Principal Consultant on Enterprise Strategy Consulting at organisation # 1 formed the basis of an exploratory study; the results of which were used to refine the research instrument and preliminary framework. Thereafter, a more rigorous empirical study focused on interviews with the Chief Architect, Senior Manager in Advisory Services and an Enterprise Architect at organizations 2, 3 and 4 respectively was conducted. The research follows an inductive approach to capture the interpretive experiences of participants and develop theoretical propositions from them. Following the exploratory pilot study it became necessary to make changes to the preliminary framework and initial survey instrument created. Thereafter, the empirical study consisting of the remaining three cases was conducted to test the important aspects of the framework and literature definitions. The analysis of the results of the empirical study prompted further changes to the theoretical framework and definitions created. The interviews conducted with each of the organizations confirmed the factors for agile EA development as well as the effectiveness of the definitions created in the literature review. The research uncovered that the need for a more agile approach to developing EA and a way to measure the level of agility of EA has become more and more significant in organizations. This begins with a better understanding of EA, agility, how agility fits within the context of EA, as well as appropriate methods to measure agility.

Abstract:

From the 1970s to the present time, the World Health Organization (WHO) explains the importance of health promotion in the world. The increased interest in promoting health and increasing health costs for the economies contributed to the recognition of health care as an important area of research. One of the most important aspects of these research currently is the Telehealth, using Information and Communication Technologies (ICT) to try to provide universal access to health. The use of Interactive Digital TV technology helps in accessing remote locations and creates the opportunity to distribute applications across their infrastructure. Dealing with the problems that arise from the convergence of these concepts is of great importance. The architectural description process helps in the development of applications and systems based on the referenced concepts. However, there are no frameworks to help the description of architectures for this particular domain. This paper proposes the ARCHealth an enterprise architecture framework created to assist the architecture development process in accordance with ISO/IEC/IEEE 42010:2011. The ARCHealth was based on the principles of primary health care, taking into account the main concerns of stakeholders and the specific area.
Desde a década de 1970 até o presente momento, a Organização Mundial da Saúde (OMS) expõe a importância da promoção da saúde no mundo. O aumento do interesse na promoção da saúde e os custos de saúde crescentes para as economias contribuíram para o reconhecimento dos cuidados à saúde como uma importante área de pesquisa. Uma das vertentes mais importantes dessas pesquisas atualmente, é a Telehealth, que utiliza das Tecnologias de Informação e Comunicação (TIC) para tentar prover acesso universal à saúde. O uso da TV Digital Interativa auxilia no acesso a locais remotos e cria a oportunidade de distribuir aplicações através de sua infraestrutura. Lidar com os problemas que surgem a partir da convergência desses conceitos é de grande importância. O processo de descrição de arquitetura auxilia no desenvolvimento de aplicações e sistemas baseados nos conceitos referenciados. Porém, não existem muitos frameworks que auxiliem a descrição de arquiteturas para esse domínio específico. Este trabalho propõe o ARCHealth, um enterprise architecture framework criado para auxiliar o processo de desenvolvimento de arquitetura em conformidade com a norma ISO/IEC/IEEE 42010:2011. O ARCHealth foi elaborado com base nos princípios de Atenção Primária à Saúde, levando em consideração as principais preocupações das partes interessadas e do domínio específico.

Abstract:

The purpose of this dissertation is to present a conceptual framework and enterprise architectural model to support information systems technology. The dissertation first discusses several information technology (IT) problems facing a typical enterprise in today's dynamic business environment, such as ineffective data management, non-integrated and fragmented systems, excessive system delivery times, user dissatisfaction, availability management, connectivity issues, Poor capacity and performance planning, inadequate data storage, ineffective security, and the question of centralization versus decentralization. Next, the rationale for the development of an effective enterprise architecture, together with a description of a new vision, is presented. An extensive literature review which addresses the significant work and findings of subject matter experts (SME) in the IT field are discussed. The dissertation then critiques and evaluates, with the assistance of these experts, fifteen already deployed information systems frameworks and architectures. Next, a view of information engineering (IE) as it relates to the enterprise architecture is addressed, because IE provides many of the foundations for the proposed enterprise architecture. The expanding role of IE has forced strategic systems planners to change the scope, objectives, style, and sources of expertise in planning. The dissertation then builds upon these concepts and proposes an enterprise architecture which provides enterprises with a structure that should allow them to support their visions, missions, objectives and goals. The enterprise architecture permits enterprises, by using open systems, to move computer application systems across different environments and platforms to various work groups and geographic locations within the various enterprises, and makes it possible for them to share processes and information with external business partners. After presenting the environmental impacts and driving forces which influence the enterprise architecture, the dissertation subsequently details each of the building blocks which constitute the enterprise architecture. The dissertation concludes by addressing several of the peripheral considerations which impact the enterprise architecture. Among these are a discussion of: business strategy development and the alignment of an organization's business strategies with information systems strategies ; the importance of perceiving information systems from a strategic perspective; strategic business initiatives; competitive positioning; an assessment of how risk analysis can be used to establish the business case for effective information systems; the development of a transition plan, and how an enterprise migrates from its embedded base of current information systems to a targeted portfolio of systems; a possible interoperability architecture; and closes with concluding comments on the enterprise architecture and its impact on the enterprise. A definition of terms, concepts, acronyms and abbreviations is presented in Appendix A. Appendix B depicts some mappings to assist with functional data modeling. Appendix C presents a taxonomy of emerging technologies which should be considered by enterprises when addressing their technical architecture. Appendix D presents an enterprise architecture example and template.

Abstract:

Information technology (IT) is critical and valuable to our society. An important type of IT system is Supervisor Control And Data Acquisition (SCADA) systems. These systems are used to control and monitor physical industrial processes like electrical power supply, water supply and railroad transport. Since our society is heavily dependent on these industrial processes we are also dependent on the behavior of our SCADA systems. SCADA systems have become (and continue to be) integrated with other IT systems they are thereby becoming increasingly vulnerable to cyber threats. Decision makers need to assess the security that a SCADA system’s architecture offers in order to make informed decisions concerning its appropriateness. However, data collection costs often restrict how much information that can be collected about the SCADA system’s architecture and it is difficult for a decision maker to know how important different variables are or what their value mean for the SCADA system’s security. The contribution of this thesis is a modeling framework and a theory to support cyber security vulnerability assessments. It has a particular focus on SCADA systems. The thesis is a composite of six papers. Paper A describes a template stating how probabilistic relational models can be used to connect architecture models with cyber security theory. Papers B through E contribute with theory on operational security. More precisely, they contribute with theory on: discovery of software vulnerabilities (paper B), remote arbitrary code exploits (paper C), intrusion detection (paper D) and denial-of-service attacks (paper E). Paper F describes how the contribution of paper A is combined with the contributions of papers B through E and other operationalized cyber security theory. The result is a decision support tool called the Cyber Security Modeling Language (CySeMoL). This tool produces a vulnerability assessment for a system based on an architecture model of it.
Informationsteknik (IT) är kritiskt och värdefullt för vårt samhälle. En viktig typ av IT-system är de styrsystem som ofta kallas SCADA-system (från engelskans "Supervisor Control And Data Acquisition"). Dessa system styr och övervakar fysiska industriella processer så som kraftförsörjning, vattenförsörjning och järnvägstransport. Eftersom vårt samhälle är beroende av dessa industriella processer så är vi också beroende av våra SCADA-systems beteende. SCADA-system har blivit (och fortsätter bli) integrerade med andra IT system och blir därmed mer sårbara för cyberhot. Beslutsfattare behöver utvärdera säkerheten som en systemarkitektur erbjuder för att kunna fatta informerade beslut rörande dess lämplighet. Men datainsamlingskostnader begränsar ofta hur mycket information som kan samlas in om ett SCADA-systems arkitektur och det är svårt för en beslutsfattare att veta hur viktiga olika variabler är eller vad deras värden betyder för SCADA-systemets säkerhet. Bidraget i denna avhandling är ett modelleringsramverk och en teori för att stödja cybersäkerhetsutvärderingar. Det har ett särskilt focus på SCADA-system. Avhandlingen är av sammanläggningstyp och består av sex artiklar. Artikel A beskriver en mall för hur probabilistiska relationsmodeller kan användas för att koppla samman cybersäkerhetsteori med arkitekturmodeller. Artikel B till E bidrar med teori inom operationell säkerhet. Mer exakt, de bidrar med teori angående: upptäckt av mjukvarusårbarheter (artikel B), fjärrexekvering av godtycklig kod (artikel C), intrångsdetektering (artikel D) och attacker mot tillgänglighet (artikel E). Artikel F beskriver hur bidraget i artikel A kombineras med bidragen i artikel B till E och annan operationell cybersäkerhetsteori. Resultatet är ett beslutsstödsverktyg kallat Cyber Security Modeling Language (CySeMoL). Beslutsstödsverktyget producerar sårbarhetsutvärdering för ett system baserat på en arkitekturmodell av det.

CAPES
While the literature on Enterprise Architecture (EA) models, frameworks, and methodologies for EA implementation has many exemplars, the field is still missing mechanisms of EA analysis. EA analysis is the process which uses any technique or method to extract information from EA models about a particular concern, in order to support EA management by the experts or inform stakeholders. In this thesis, we model the EA as a complex network, a concept discussed in network science, to analyze EA structural aspects. During our exploratory study about EA network analysis (EANA), it was clear that the field was still lacking foundational aspects. First, no common language was shared by researchers. Secondly, there was no clarity about what concerns could be analyzed with network analysis initiatives and thirdly, the techniques and methods´ implementation were not clear in the papers. We solve those gaps in order to describe how to perform analysis of EA components and their relationships supported by network measures. The research approach comprehends qualitative methods such as systematic literature review, thematic analysis and design science research method. The research is conducted in three complementary and interrelated phases, aiming at first, to collect and synthesize the available knowledge about the analysis approaches existent in the literature. Next, we aim to trace a comprehensive understanding of the main concepts involved in EANA such as their analysis concerns, modeling decisions, inputs required and steps necessary to perform it. Altogether, this resulted in a set of six proposed artifacts: EANA meta-model, EANA library, EANA process, EANA data derivation strategy. Finally, we investigate the use of those artifacts, evaluating them empirically through their instantiations and/ or with the help of EA experts of three German multinational companies. The evaluation results were positive regarding, among other criteria, the efficacy and utility of the proposed artifacts in their respective contexts. As contributions, we claim the definition of the conceptual foundations of the EANA research field. Complementary, the study is not limited to the theoretical findings since it advances the understanding of empirical network analysis, whereas it offers a library of analysis initiatives, methods to derive EA data and guidelines to help experts through the analysis process (EANA process). Finally, we also add to the EANA knowledge base two new EANA methods which were also empirically evaluated. We expect that results can enhance the awareness researchers and practitioners about the EA network-based analysis´ efficacy and utility, a step necessary to develop more rationally grounded methods and tools to support the EA management considering structural aspects.
técnicas ou métodos para extrair informações arquiteturais sobre um aspecto de interesse sobre a AE, a partir de modelos, e com o objetivo de dar suporte aos especialistas no gerenciamento da AE ou ainda pra informar seus stakeholders. Nesta tese, a AE é modelada como uma rede complexa, um conceito originário da teoria de redes, com o objetivo de analisar aspectos estruturais de AE. Durante o estudo exploratório sobre a análise de redes aplicada ao contexto de AE, constatamos a ausência de fundamentos conceituais básicos como, por exemplo, um nivelamento conceitual entre os autores dos trabalhos; desconhecimento sobre a abrangência dos estudos de análise estrutural no contexto de AE e finalmente, carência de informação acerca do processo de análise estrutural realizado nos trabalhos. Nosso objetivo principal na tese é investigar como as métricas e métodos de análise de redes podem sem aplicados no contexto de análise de AE. Métodos qualitativos de pesquisa como revisão sistemática de literatura, análise temática e design science research foram utilizados em três fases complementares e inter-relacionadas. Primeiramente, para coletar e consolidar o conhecimento sobre abordagens de análise de AE existentes na literatura. Numa segunda etapa, o objetivo foi traçar um entendimento abrangente sobre os principais conceitos envolvidos na análise estrutural de AE, mapeando seus métodos e técnicas utilizados, culminando com o design de quatro artefatos propostos: um meta-modelo para análise de redes no contexto de AE; uma biblioteca reunindo as iniciativas de análise extraídas dos artigos; um processo de análise de redes para AE e uma estratégia para derivação de dados. Na terceira e última etapa, investigou-se o uso dos artefatos avaliando-os empiricamente por meio de suas instanciações e da opinião de especialistas em AE de três organizações multinacionais alemãs. Os resultados foram positivos considerando, dentre outros critérios, a eficácia e utilidade dos artefatos propostos nos seus respectivos contextos. Como contribuições, esta pesquisa define os conceitos fundamentais para análise de redes em AE, além de avançar no entendimento acerca da análise empírica de redes naquele contexto, uma vez que apresenta um catálogo de métricas e métodos para derivação de dados, além de um processo para auxiliar os especialistas ao longo da execução da análise. Finalmente, a pesquisa também contribui para a base de conhecimento com dois métodos de análise validados também empiricamente. Com base nos resultados, espera-se corroborar o potencial da análise de AE baseada em redes, sua eficácia e utilidade para pesquisadores e práticos, além de estimular a adoção e desenvolvimento de ferramental para suportar o gerenciamento de AE, considerando seus aspectos estruturais.

Abstract:

Information technology has become increasingly important to individuals and organizations alike. Not only does IT allow us to do what we always did faster and more effectively, but it also allows us to do new things, organize ourselves differently, and work in ways previously unimaginable. However, these advantages come at a cost: as we become increasingly dependent upon IT services, we also demand that they are continuously and uninterruptedly available for use. Despite advances in reliability engineering, the complexity of today's increasingly integrated systems offers a non-trivial challenge in this respect. How can high availability of enterprise IT services be maintained in the face of constant additions and upgrades, decade-long life-cycles, dependencies upon third-parties and the ever-present business-imposed requirement of flexible and agile IT services? The contribution of this thesis includes (i) an enterprise architecture framework that offers a unique and action-guiding way to analyze service availability, (ii) identification of causal factors that affect the availability of enterprise IT services, (iii) a study of the use of fault trees for enterprise architecture availability analysis, and (iv) principles for how to think about availability management. This thesis is a composite thesis of five papers. Paper 1 offers a framework for thinking about enterprise IT service availability management, highlighting the importance of variance of outage costs. Paper 2 shows how enterprise architecture (EA) frameworks for dependency analysis can be extended with Fault Tree Analysis (FTA) and Bayesian networks (BN) techniques. FTA and BN are proven formal methods for reliability and availability modeling. Paper 3 describes a Bayesian prediction model for systems availability, based on expert elicitation from 50 experts. Paper 4 combines FTA and constructs from the ArchiMate EA language into a method for availability analysis on the enterprise level. The method is validated by five case studies, where annual downtime estimates were always within eight hours from the actual values. Paper 5 extends the Bayesian prediction model from paper 3 and the modeling method from paper 4 into a full-blown enterprise architecture framework, expressed in a probabilistic version of the Object Constraint Language. The resulting modeling framework is tested in nine case studies of enterprise information systems.
Informationsteknik blir allt viktigare för både enskilda individer och för organisationer. IT låter oss inte bara arbeta snabbare och effektivare med det vi redan gör, utan låter oss också göra helt nya saker, organisera oss annorlunda och arbeta på nya sätt. Tyvärr har dessa fördelar ett pris: i takt med att vi blir alltmer beroende av IT-tjänster ökar också våra krav på att de är ständigt tillgängliga för oss, utan avbrott. Trots att tillförlitlighetstekniken går framåt utgör dagens alltmer sammankopplade system en svår utmaning i detta avseende. Hur kan man säkerställa hög tillgänglighet hos IT-tjänster som ständigt byggs ut och uppgraderas, som har livscykler på tiotals år, som är beroende av tredjepartsleverantörer och som dessutom måste leva upp till verksamhetskrav på att vara flexibla och agila? Den här avhandlingen innehåller (i) ett arkitekturramverk som på ett unikt sätt kan analysera IT-tjänsters tillgänglighet och ta fram rekommenderade åtgärder, (ii) ett antal identifierade kausalfaktorer som påverkar IT-tjänsters tillgänglighet, (iii) en studie av hur felträd kan användas för arkitekturanalys av tillgänglighet samt (iv) en uppsättning principer för beslutsfattande kring tillgänglighet. Avhandlingen är en sammanläggningsavhandling med fem artiklar. Artikel 1 innehåller ett konceptuellt ramverk för beslutsfattande kring IT-tjänsters tillgänglighet som understryker vikten av variansen hos nertidskostnaderna. Artikel 2 visar hur ramverk för organisationsövergripande arkitektur (s.k. enterprise architecture -- EA) kan utvidgas med felträdsanalys (FTA) och bayesianska nätverk (BN) för analys av beroenden mellan komponenter. FTA och BN är bägge etablerade metoder för tillförlitlighets- och tillgänglighetsmodellering. Artikel 3 beskriver en bayesiansk prediktionsmodell för systemtillgänglighet, baserad på utlåtanden från 50 experter. Artikel 4 kombinerar FTA med modelleringselement från EA-ramverket ArchiMate till en metod för tillgänglighetsanalys på verksamhetsnivå. Metoden har validerats i fem fallstudier, där de estimerade årliga nertiderna alltid låg inom åtta timmar från de faktiska värdena. Artikel 5 utvidgar den bayesianska prediktionsmodellen från artikel 3 och modelleringsmetoden från artikel 4 till ett fullständigt EA-ramverk som uttrycks i en probabilistisk version av Object Constraint Language (OCL). Det resulterande modelleringsramverket har testats i nio fallstudier på verksamhetsstödjande IT-system.

Abstract:

This thesis explores the potential to unify three emerging disciplines: enterprise engineering, enterprise architecture and enterprise ontology. The current fragmentation that exists in literature on enterprise alignment and design constrains the development and growth of the emerging disciplines. Enterprises need to use a multi-disciplinary approach when they continuously align, design and re-design the enterprise. Although enterprises need to be aligned internally (across various enterprise facets), as well as externally (with the environment), most alignment approaches still focus on business-IT alignment, i.e. aligning the business operations with the information and communication technologies and systems of the enterprise. This study focuses on a popular business-IT alignment approach,called the foundation for execution approach, and its associated artefact, called the operating model. The study acknowledges the theoretical contribution of the operating model to establish the required level of business process integration and standardisation at an enterprise in delivering goods and services to customers. Highlighting the practical problems in selecting an operating model for an enterprise, and more specifically the practical problems of identifying process reuse potential at an enterprise, a thesis statement is formulated: The operating model concept, as part of a business-IT alignment approach, can be enhanced with a process reuse identification framework, when a business-IT alignment contextualisation is used. The study is divided into two research questions. The first research question addresses the current fragmentation that exists in the literature, which impairs reuse of the existing business-IT alignment knowledge base. An inductive literature review develops the Business-IT Alignment Model to provide a common contextualisation for current business-IT alignment approaches. The second research question addresses the practical problems of the operating model regarding the identification of process reuse potential at an enterprise. Applying the newly developed Business-IT Alignment Model as a contextualisation instrument, the study demonstrates the use of design research in developing the Process Reuse Identification Framework. The conclusion after the investigation of the two research questions is that the thesis statement was confirmed, i.e. the operating model concept, as part of a business-IT alignment approach, can be enhanced with a process reuse identification framework, when a business-IT contextualisation is used.

Abstract:

Information Technology (IT) is a cornerstone of our modern society and essential for governments' management of public services, economic growth and national security. Consequently, it is of importance that IT systems are kept in a dependable and secure state. Unfortunately, as modern IT systems typically are composed of numerous interconnected components, including personnel and processes that use or support it (often referred to as an enterprise architecture), this is not a simple endeavor. To make matters worse, there are malicious actors who seek to exploit vulnerabilities in the enterprise architecture to conduct unauthorized activity within it. Various models have been proposed by academia and industry to identify and mitigate vulnerabilities in enterprise architectures, however, so far none has provided a sufficiently comprehensive scope. The contribution of this thesis is a modeling framework and calculation engine that can be used as support by enterprise decision makers in regard to cyber security matters, e.g., chief information security officers. In summary, the contribution can be used to model and analyze the vulnerability of enterprise architectures, and provide mitigation suggestions based on the resulting estimates. The contribution has been tested in real-world cases and has been validated on both a component level and system level; the results of these studies show that it is adequate in terms of supporting enterprise decision making. This thesis is a composite thesis of eight papers. Paper 1 describes a method and dataset that can be used to validate the contribution described in this thesis and models similar to it. Paper 2 presents what statistical distributions that are best fit for modeling the time required to compromise computer systems. Paper 3 describes estimates on the effort required to discover novel web application vulnerabilities. Paper 4 describes estimates on the possibility of circumventing web application firewalls. Paper 5 describes a study of the time required by an attacker to obtain critical vulnerabilities and exploits for compiled software. Paper 6 presents the effectiveness of seven commonly used automated network vulnerability scanners. Paper 7 describes the ability of the signature-based intrusion detection system Snort at detecting attacks that are more novel, or older than its rule set. Finally, paper 8 describes a tool that can be used to estimate the vulnerability of enterprise architectures; this tool is founded upon the results presented in papers 1-7.
Informationsteknik (IT) är en grundsten i vårt moderna samhälle och grundläggande för staters hantering av samhällstjänster, ekonomisk tillväxt och nationell säkerhet. Det är därför av vikt att IT-system hålls i ett tillförlitligt och säkert tillstånd. Då moderna IT-system vanligen består av en mångfald av olika integrerade komponenter, inklusive människor och processer som nyttjar eller stödjer systemet (ofta benämnd organisationsövergripande arkitektur, eller enterprise architecture), är detta tyvärr ingen enkel uppgift. För att förvärra det hela så finns det även illvilliga aktörer som ämnar utnyttja sårbarheter i den organisationsövergripande arkitekturen för att utföra obehörig aktivitet inom den. Olika modeller har föreslagits av den akademiska världen och näringslivet för att identifiera samt behandla sårbarheter i organisationsövergripande arkitekturer, men det finns ännu ingen modell som är tillräckligt omfattande. Bidraget presenterat i denna avhandling är ett modelleringsramverk och en beräkningsmotor som kan användas som stöd av organisatoriska beslutsfattare med avseende på säkerhetsärenden. Sammanfattningsvis kan bidraget användas för att modellera och analysera sårbarheten av organisationsövergripande arkitekturer, samt ge förbättringsförslag baserat på dess uppskattningar. Bidraget har testats i fallstudier och validerats på både komponentnivå och systemnivå; resultaten från dessa studier visar att det är lämpligt för att stödja organisatoriskt beslutsfattande. Avhandlingen är en sammanläggningsavhandling med åtta artiklar. Artikel 1 beskriver en metod och ett dataset som kan användas för att validera avhandlingens bidrag och andra modeller likt detta. Artikel 2 presenterar vilka statistiska fördelningar som är bäst lämpade för att beskriva tiden som krävs för att kompromettera en dator. Artikel 3 beskriver uppskattningar av tiden som krävs för att upptäcka nya sårbarheter i webbapplikationer. Artikel 4 beskriver uppskattningar för möjligheten att kringgå webbapplikationsbrandväggar. Artikel 5 beskriver en studie av den tid som krävs för att en angripare skall kunna anskaffa kritiska sårbarheter och program för att utnyttja dessa för kompilerad programvara. Artikel 6 presenterar effektiviteten av sju vanligt nyttjade verktyg som används för att automatiskt identifiera sårbarheter i nätverk. Artikel 7 beskriver förmågan av det signatur-baserade intrångsdetekteringssystemet Snort att upptäcka attacker som är nyare, eller äldre, än dess regeluppsättning. Slutligen beskriver artikel 8 ett verktyg som kan användas för att uppskatta sårbarheten av organisationsövergripande arkitekturer; grunden för detta verktyg är de resultat som presenteras i artikel 1-7.

Full text

Abstract:

Crowds are often an integral part of an event or an activity that may potentially be overlooked, yet present a substantial threat to the health and safety of all those attending such an event. In the majority of crowd control situations, the importance of managing the event will not simply rest with the event managers themselves, but is likely to involve having to create efficient enterprise wide systems which several third parties would need to interact with, in order to deal with difficulties, should they arise, such as the need to liaise with the police or fire service, as appropriate. This research focuses on the practices of crowd management and the way in which those involved in crowd management should potentially change their approach, in order to enhance safety, but also to enhance the efficiency of managing and controlling the crowd, something which is becoming increasingly important, given the economic impact that large-scale events can have on a region. To enable the above a Crowd Control and Management Enterprise Modelling (CCMEM) framework was developed. The first stage of this was the synthesis of the appropriate components within various existing crowd management models found in literature. This synthesis, formed the basis of the theoretical components from which the Mega Event Command and Control Architecture (MECCA) framework was developed. This framework was evaluated with two case studies involving very large or mega events, ! namely the Hajj to Mecca and the London Olympics 2012. A research study that used both qualitative and quantitative methods to collect primary data was designed, which further developed and validated the CCMEM and the MECCA frameworks. The application of MECCA framework with the two case studies was evaluated using the Crowd Management Evaluation Components (CMEC). When looking at the results of the data collected and the case studies in this particular research, it became apparent that the enterprise wide view understanding of mega event management enabled the effective mapping of and development of associated integrated systems for each of the components of the framework. This in turn leads to more efficient and effective crowd management. Also this better understanding enables officials to react much more effectively and much more quickly to changes in the crowd dynamics. Further work can be carried out to develop the various integrated information systems which will be required and this will be based on the enterprise wide CCMEM - MECCA framework.

The need to relate the various architectural domains captured in partial descriptions of an enterprise is addressed in virtually all enterprise modeling approaches. One of these domains, namely that of organizational behavior, has received significant attention in recent years in the context of business process modeling and management. Another important domain, that of organizational structure is strongly inter-related with the process domain. While the process domain focuses on how the business process activities are structured and performed, the organizational structure domain focuses on who performs these activities, i.e., which kinds of entities in an organization are capable of performing work. Given the strong connection between the organizational behavior and organizational resources, we argue that any comprehensive enterprise modeling technique should explicitly establish the relations between the modeling elements that represent organizational behavior, called here behavioral elements, and those used to represent the organizational resources (organizational actors) involved in these activities, called here active structure elements. Despite the importance of the relations between these architectural domains, many of the current enterprise architecture and business process modeling approaches lack support for the expressiveness of a number of important active structure allocation scenarios. This work aims to overcome these limitations by proposing a framework for active structure assignment that can be applied to enterprise architecture and business process modeling approaches. This framework enriches the expressiveness of existing techniques and supports the definition of precise active structure assignments. It is designed such that it should be applicable to a number of enterprise architecture and business process modeling languages, i.e., one should be able to use and apply different (enterprise and business process) modeling languages to the framework with minor changes
A necessidade de se relacionar os vários domínios arquiteturais capturados em descrições parciais de uma organização é, virtualmente, tratado em todas as abordagens de modelagem de arquiteturas organizacionais. Um destes domínios, particularmente chamado de comportamento organizacional, tem recebido atenção significativa nos últimos anos no contexto de modelagem e gerenciamento de processos de negócio. Outro domínio importante, chamado de estrutura organizacional, é fortemente inter-relacionado com o domínio de processo. Enquanto o domínio de processo foca em "como" as atividades de processos de negócio são estruturadas e executadas, o domínio de estrutura organizacional foca em "quem" executa essas atividades, i.e., quais tipos de entidades em uma organização são capazes de executar trabalho. Dada a forte conexão entre o comportamento organizacional e os recursos organizacionais, nós argumentamos que qualquer técnica de modelagem de arquitetura organizacional deve explicitamente estabelecer relações entre os elementos de modelagem que representam o comportamento organizacional, chamado aqui de elementos comportamentais e aqueles suados para representar recursos organizacionais (atores organizacionais) envolvidos nestas atividades, chamados aqui de elementos da estrutura ativa. Apesar da importância das relações entre esses domínios arquiteturais, muitas das abordagens de modelagem de processo de negócio e modelagem de arquiteturas organizacionais tem um suporte insuficiente para expressar uma quantidade importante de cenários de alocação da estrutura ativa. Este trabalho visa superar essas limitações propondo um framework para a atribuição da estrutura ativa que pode ser aplicado a abordagens de modelagem de processo de negócio e modelagem de arquitetura organizacionais. Esse framework enriquece a expressividade das técnicas existentes e dá suporte à definição de atribuições precisas da estrutura ativa. Ele é desenvolvido tal que pode ser aplicável a linguagens de modelagem de processo de negócio e linguagens de modelagem de arquiteturas organizacionais, i.e., é possível utilizar e aplicar diferentes linguagens de modelagem ao framework com mudanças mínimas

Abstract:

This thesis deals with a field of information modeling and its relation to systems architecture. It is divided into two notional parts -- theoretical (first and second chapter) and practical (third and fourth chapter). First chapter explains the meaning of the term 'information model', compares it to the term 'data model' and then introduce its practical use in an enterprise modeling. It also defines the term of 'systems architecture' in its broad meaning and reduces it to three narrow meaning -- enterprise architecture, information architecture and information systems architecture, while it explains their relation to the information modeling. Finally this chapter provides the base for information model implementation methodology created later in the practical part of this thesis. Second chapter introduces architecture framework called TM Forum Frameworx specialized for a telecommunication services provider. It consists of three standards for business process, information and application architecture. The second one defines specific information model which is described partly in the second chapter and partly in the appendix B of this thesis. Third chapter describes the first of two contributions of this thesis - the information model implementation methodology. This methodology is applicable to any implementation of an information model. Three sections of this chapter contains diagrams and description of three phases of the methodology - pre-implementation phase, implementation phase and post-implementation phase. In the end of the chapter there is a table containing outputs of every single activity performed during all the phases. Fourth and last chapter then describes and evaluates real implementation of the information model from TM Forum Frameworx in the systems architecture department of an enterprise providing telecommunication services. This implementation based on the created methodology and its successful results then became the second contribution of this thesis.

Abstract:

Virtual Organizations (VO)—a network of independent organizations collaborating to address specific business opportunities—have become popular in today’s technology driven business environment. Due to their autonomous and interdependent nature, management of collaboration among such organizations is a challenging task. Although many solutions have been proposed over the past two decades to support inter-organizational interactions, VOs still face several challenges due to their dynamic and temporal nature that cannot be addressed by traditional solutions such as ebXML, RosettaNet and EDI. In this research, we present a framework for process management in service oriented virtual organizations and a distributed architecture for a flexible infrastructure that supports collaborative business process execution, monitoring and management. The framework contains 6 layers with multiple components within each layer. In designing the components of the framework, standard reference architecture such as the Open-EDI reference model and the S3 service oriented architecture, as well as best practices such as ITIL V3 and PMBOK are used. The infrastructure supports the common topologies of inter-organizational collaboration (e.g. peer-to-peer, star, linear), and responds well to changes due to its loosely coupled components. The proposed infrastructure is based on federating multiple SOA infrastructures with the Enterprise Service Bus (ESB) as its core. It is implemented using IBM WebSphere ™ products. We demonstrate that VOs built with our framework and implementation architecture facilitate flexibility, rapid process integration and dynamic evolution.

Abstract:

In today's economics, medium and large-size companies are trying to gain a competitive advantage from specialization and centralization of supporting services. This trend affects also areas of enterprise architecture and integration where they establish particular teams to support the disciplines in regular manner. Despite a lot of research activities oriented towards these topics, there are only a few focusing on organizational aspects and cooperation between enterprise architecture and integration teams. As the companies are on different levels of the maturity in both areas and focusing on different aspects of architecture and integration, there is no simple solution that could provide detailed guidelines for establishing the right cooperation approach. Goal of this dissertation is to propose a cooperation model for architecture and integration teams that should make cooperation between such teams more efficient. Integral part of the dissertation is to verify the model in real environment. The model is built on top of integration activities performed either in enterprise architecture or integration teams or both. These activities are categorized into particular integration areas and relations are identified between integration areas and architecture areas defined according to TOGAF architecture framework. The resulting model is then being used to depict various kind of cooperation between architecture and integration teams based on the companys' integration goals. Verification of the model is performed in financial enterprise in two cases and confirms the benefits of the model.

Organization Performance Analysis Framework (OPAF) is a Metamodel which analyzes performance of organizational structure using Enterprise Architecture Analysis Tool (EAAT). This quantitative analysis is used to find out which structure is good at learning, motivation, efficiency, productivity, etc. and how to change it. Current framework does not include IT and how it affects the organizational structure. This thesis work will try to find out how IT affects organizational structure, directly and indirectly. The effect is translated in Object Constraint Language (OCL) and inserted in the model. The framework IT-OPAF is used to analyze three real life organizations and see the changes in performance when IT is introduced. This will validate the findings and also recognize pattern of the effect of IT on organizational structure.

Abstract:

Aging infrastructure and personnel, combined with stricter financial constraints has put maintenance, or more popular Asset Management, at the top of the agenda for most power utilities. At the same time the industry reports that this area is not properly supported by information systems. Today’s power utilities have very comprehensive and complex portfolios of information systems that serve many different purposes. A common problem in such heterogeneous system architectures is data management, e.g. data in the systems do not represent the true status of the equipment in the power grid or several sources of data are contradictory. The research presented in this thesis concerns how this industrial problem can be better understood and approached by novel use of the ontology standardized in the Common Information Model defined in IEC standards 61970 & 61968. The theoretical framework for the research is that of data management using ontology based frameworks. This notion is not new, but is receiving renewed attention due to emerging technologies, e.g. Service Oriented Architectures, that support implementation of such ontological frameworks. The work presented is empirical in nature and takes its origin in the ontology available in the Common Information Model. The scope of the research is the applicability of the CIM ontology, not as it was intended i.e. in systems integration, but for analysis of business processes, legacy systems and data. The work has involved significant interaction with power distribution utilities in Sweden, in order to validate the framework developed around the CIM ontology. Results from the research have been published continuously, this thesis consists of an introduction and summary and papers describing the main contribution of the work. The main contribution of the work presented in this thesis is the validation of the proposition to use the CIM ontology as a basis for analysis existing legacy systems. By using the data models defined in the standards and combining them with established modeling techniques we propose a framework for information system management. The framework is appropriate for analyzing data quality problems related to power systems maintenance at power distribution utilities. As part of validating the results, the proposed framework has been applied in a case study involving medium voltage overhead line inspection. In addition to the main contribution, a classification of the state of the practice system support for power system maintenance at utilities has been created. Second, the work includes an analysis and classification of how high performance Wide Area communication technologies can be used to improve power system maintenance including improving data quality.

Abstract:

This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks. The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models. Furthermore these values are based on several different sources on how to measure usability. The complete contents of the framework and the underlying ideas, upon which the framework is based, are presented in this report. The framework in this study was designed in order to enable it to be used universally with any modelling language in conjunction with a modelling tool. Its design is also not limited to the field of computer security and computer networks, although that is the intended context of CySeMoL as well as the context described in this report. However, utilization outside the intended area of usage will most likely require some modifications, in order to work in a fully satisfying. Several flaws where uncovered regarding the usability of CySeMoL and EAAT, but this is also accompanied by several recommendations on how to improve both CySeMoL and EAAT. Because of the outline of the framework, the most severe flaws have been identified and recommendations on how to rectify these shortcomings have been suggested.

Abstract:

We believe there to be a possible problem with Enterprise Architecture, in that in using standardizations such as frameworks stifles creativity and innovations, focusing on IT-environments. This assumption is not new as there already are thoughts in existence on this subject, each side discussing if there is a fault or not. Out of our own interest we delve deeper into the subject of Enterprise Architecture to see if there is any truth in our assumption and to see if there is anything anyone can do to compensate or solve this perceived problem. We look into what Enterprise Architecture consists of and examine four different popular frameworks associated with it: TOGAF, FEA, Gartner and Zachman. We learn about creativity in Information Systems organizations and its connection to IT. Our research strategy for this thesis is deduction together with two separate phases, one phase is exploratory and the other descriptive. We examine the nature of creativity and innovation, there too with an emphasis on IT. In order to find out if our assumption is correct we seek out literature, articles and other sources of information on innovations, creativity and frameworks. Armed with this information we seek out and perform interviews with people from large commercial organizations who have hands-on work experience working with Enterprise Architecture in order to see if our assumptions have any form of validity and to gain some insight into the subject matter. The method components for this thesis are literature review, document study and interviews. Analyzed with the help of SWOT we use the data gathered from the interviews to gain a visual representation of the results, to see the pros and cons of Enterprise Architecture. The results show that supplements or tools are used in order to produce or support business innovations, using departments, business related social networks or techniques to compensate. Hampering factors for business innovation can be internal conflicts, struggles between different groups for different EA solutions. Promoting business innovation through EA can come from mixing framework bits together, giving the result of a flexible and adaptive framework. It can also come from acting as a common language and a bridge between different hierarchies. EA aids with difficult decisions, evaluating which alternatives for realization and the order services are realized. Meetings can be used to compensate the lack of creativity and innovation rising from EA. A negative consequence of EA can occur during implementation of things related to EA in larger companies. No examples of companies that failed with creating business innovation in their IT with EA were found.

Abstract:

Enterprise architecture frameworks (EAFs) have been used to plan and manage large-scale enterprise deployments for more than four decades. EAFs are important tools used by systems engineers and are integral to characterize enterprise information architectures. They are increasingly being used as a proxy for managing entire organizations – enterprises. Enterprises represent complex, multi-disciplinary, socio-technical systems. They are ubiquitous, and involve and affect a vast number of humans every day. However, as inter-disciplinary tools for the management of the enterprise, there are certain limitations to the efficacy of existing enterprise architecture frameworks. The effective management of enterprises presents significant challenge and opportunity for the systems engineering community. This research discusses the limitations of, and proposes enhancements to, existing EAFs, based on research into extant business management frameworks. An historical perspective is provided on both systems engineering and business enterprise domain frameworks. Research into the common elements of successful business management frameworks confirms the limitations of existing systems engineering frameworks and suggests key additions for enhanced efficacy. The applicability and relevance of enhancing extant enterprise architectures with elements from extant business frameworks is examined. Finally, recommendations are made for enhancements to extant frameworks and suggestions advanced on future research into efficacy. This dissertation concludes with implications of these findings for systems engineers engaged in enterprise architecture and enterprise transformation efforts and a recommendation that systems engineers take a more holistic approach in their enterprise architecture and enterprise transformation efforts.

Early-stage enterprises are characterized by leveraging limited resources during periods of accelerating industry growth and relatively high uncertainty. This thesis is an examination of an early-stage enterprise within the medical technology industry using multiple frameworks. In addition to the standard Lean Advancement Initiative (LAI) suite of tools, the enterprise will be evaluated using Nightingale and Rhodes' eight Enterprise Architecture (EA) views, Kaplan's Balanced Scorecard (BSC), McKinsey's 7S framework, and Grave's Spiral Dynamics. Moreover, this thesis includes a practical examination of the current state using the framework developed by Piepenbrock's doctoral thesis that introduced the notion of modular versus integral enterprise architectures. A transformation plan is proposed based on the firm's current state and preferred future state based on insights from the various self-assessments and prevailing corporate strategy. The transformation plan is also informed by the author's perceived receptivity, commitment and need for change of the organization. The case organization's current state is described in general terms to protect the company's identity since the material presented includes portions of their corporate strategy and source of competitive advantage. Recognizing that all competitive advantage is temporary, considerable care has been exercised to balance the relevance of the research with the privacy needs of the organization.

Abstract:

Most large modern enterprises comprise different departments, subsidiaries, and divisions internally, and each of these will typically operate multiple, interdependent, information technology systems. Externally, all enterprises face dynamic and sometimes turbulent environments, with ongoing changes in laws and regulations, technologies, competition, customer preferences, and marketplace changes. These ongoing external dynamics will impact on the enterprise’s goals and strategies, and thus on their IT systems and processes. Enterprise architecture management (EAM) frameworks have proven to be a valuable and widespread means of representing the internal IT systems of enterprises, and of representing links of these systems to the organization’s goals and strategies. But how well do EAM frameworks cope with the dynamic envi-ronments that organizations face? It turns out not well. Indeed, common EAM frameworks are mostly static. In practice, enterprises opt to build their own adapted approach on top of standard frameworks. Stakeholders use their capacity and attempt to incorporate implicit knowledge and business behaviour specific to their own enterprise. Based on an action research case study undertaken in a large, complex business enterprise in Saudi Arabia, we propose a methodology for managing changing business behaviour. This builds on selecting existing and well-established approaches in line with EAM frameworks. This is achieved by an extended meta-model offering further capacity with new constituents enabling the representation of time-knowledge for changing sources of information, and new constituents enabling constant maintenance of enterprise architecture (EA) models. In addition, the incorporation of the changing business behaviour is facilitated via guidelines for the modelling of different stakeholders’ collective-thinking/mental-modelling in order to offer a shared understanding of business behaviour. Furthermore, we propose a number of techniques relying on the ex-tended meta-model to facilitate the constant maintenance of the EA landscape. These techniques use the capacity of the extended meta-model to represent multiple states of the EA reflecting changing elements to compliment the architectural development method (ADM) of the open group architecture framework (TO-GAF). Our methodology is driven by action research to ensure the applicability and real-world relevance of our solution, which is itself a novel approach in the EAM field.

Abstract:

Business architecture is compared to the enterprise architecture discipline still unexplored. While a number of papers and literature on enterprise architecture has been written, business architecture remains behind in this respect. This thesis mainly deals with the creation of a conceptual model of business architecture artifacts and comparing them with open source tools. The primary objective of this study is to compare open source tools to support the business architecture artifacts. To fulfill this primary objective is important secondary objective. The secondary objective is to analyze the most highly cited expert articles and scientific literature and analyzing the most common architectural frameworks in organizations. Based on the analysis of these sources of information create conceptual artifacts BA model with the largest number of their occurrence. These artifacts will be assigned to specific models, which fulfill them. After reaching the secondary target, comes the fulfillment of the primary objectives. Then selected open source tools will be compared with that created a conceptual model and evaluated as a measure of its fulfillment.

Abstract:

Digital Transformation (DT) opens up to new opportunities for companies by providing organizational flexibility and improving their business models. Due to lack of resources in form of financial power and qualified employees, family-owned manufacturing companies have a hard time reaching DT. However, these companies try their best to reach DT and along the road various challenges arise. The challenges that arise, result in a complex situation that is hard to understand. Organizations with complex situations have difficulties to perform successful IT initiatives that are required to reach DT. The aim of this study was to identify challenges that family-owned manufacturingSMEs (FOMSMEs) encounter when striving for DT. Another aim of this research was to investigate how useful Soft Systems Methodology (SSM) is in helping family-owned manufacturing SMEs to understand their own complex situation. Also, the managerial practice called Enterprise Architecture Management (EAM) has been investigated regarding its usefulness in helping family-owned manufacturing SMEs to reach DT faster and easier. As a fourth and final aim in this study, an artefact has been created with suggested actions that address the identified challenges that FOMSMEs encounter when striving for DT. By interviewing employees who have participated in IT initiatives at a family-owned manufacturing SME, this research has been able to answer the research questions. Several challenges were identified; communication errors, old systems and exceeding deadlines in projects. All of these challenges can, with the help of SSM, be associated with the identified root challenge: Lack of overview of IT-landscape and strategy. The informants’ thoughts of usefulness of SSM in family-owned manufacturing SMEs were positive. In contrast, the informants’ thoughts of usefulness of EAM in family-owned manufacturing SMEs were negative. The argument expressed by the informants was that as long as the owner family makes most of the decisions, a new managerial practice as EAM will not be useful in family-owned manufacturing SMEs.

Abstract:

Network documentation is often a low-priority task at many companies. Despite this, there are many benefits that should be considered against the fact that it is a comprehensive job. Good network documentation can provide companies the opportunity to reduce dependence on individuals, take proactive decisions and save money. Network documentation mainly consist of physical and/or logical topology descriptions that describes the logical and/or physical layout of the network. These so-called architectural views focus on technology rather than the services and features that the company's network provides. To simplify communication between stakeholders with different areas of knowledge, e.g. between an engineers and corporate management, I propose a model that complement traditional visual description of a network. With the help of viewpoint frameworks such as Kruchten's "4+1" model, I want to visualize relationships between corporate services, business processes, applications and the underlying infrastructure. A qualitative case study at a company with needs of network documentation has resulted in a prototype, a viewpoint framework, based on concepts of enterprise architecture. Analyzing a use case together with the prototype demonstrated that the prototype can visualize relationships between different layers in an organization. The prototype can be used as a starting point or guidance for those who want to document architecture of an enterprise network. The prototype can serve as means of communication in order to justify the investment that in turn ensures a modern energy-efficient operating environment that creates conditions for sustainable information- and communication technology.
Nätverksdokumentation är ofta lågt prioriterat på många företag idag. Men det finns många fördelar som borde vägas mot det faktum att det är ett omfattande jobb. Bra nätverksdokumentation kan ge företag möjligheten att minska personberoende, ta proaktiva beslut och spara pengar. Nätverksdokumentation består huvudsakligen av fysiska och/eller logiska topologidiagram, som beskriver nätverkets utformning. Dessa så kallade vyer fokuserar mer på teknik än de tjänster och funktioner som företagets nätverk tillhandahåller. För att förenkla kommunikation mellan olika intressenter med olika kunskapsbakgrund, t.ex. mellan ingenjörer och ledningen på ett företag, föreslår jag en modell som kompletterar den traditionella visuella beskrivningen av ett nätverk. Med hjälp av ramverk för vyer som t.ex. Kruchtens "4+1" modell, vill jag synliggöra samband mellan företagets tjänster, affärsprocesser, applikationer och den underliggande infrastrukturen. En kvalitativ fallstudie hos ett företag med behov av nätverksdokumentation har resulterat i en prototyp, ett ramverk för vyer, som bygger på koncept inom verksamhetsarkitektur. Analys av ett användarfall med prototypen som underlag demonstrerade att modellen kan synliggöra samband mellan olika skikt i en organisation. Prototypen kan användas som utgångspunkt för den som vill dokumentera arkitekturen hos ett företagsnätverk. Min modell kan fungera som ett kommunikationsmedel för att kunna motivera investeringar i nätverket, som i sin tur säkerställer en modern driftmiljö som skapar förutsättningar för hållbar informations- och kommunikationsteknik.

Abstract:

This research project endeavors to frame a methodology that can be used to categorize firm value strategies (production logics) and choices of factor inputs (tangible and intangible assets), which are used to fuel production cycles for goods and services outputs. A secondary goal of the research is to attempt to determine what asset group combinations (resources) are combined by various classes of firms to produce sustainable outcomes for the A/E/C firms in the survey. The National Bureau of Economic Research recently issued a system of national accounts (acknowledging both tangible and intangible assets) that reflects the macro-economy but at the same juncture, lamented the fact that a firm-level micro-economic schema did not exist to mirror the national system. This study makes an effort to redress that void by investigating how such a system of accounts - measured on the input side of the ledger -- could begin to fill in a gap in information and understanding as pointed out by participants in the National Academy of Sciences symposium of 2009 entitled "Intangible Assets: Measuring and Enhancing Their Contribution to Corporate Value and Growth." In brief, the research represents an effort to make a contribution to a growing body of knowledge about intangible assets by solidifying a framework within which both tangible and intangible assets may be more appropriately conceptualized and more adequately measured for purposes of current and future investigations. The research also provides a methodology for beginning to understand how some design and construction industry firms rely on specific asset categories for operating success, corporate stock value and business continuity. It is conceivable that managers would use a variation of the methodology to better balance ongoing investments in their firm's portfolio of tangible and intangible resources. The mixed methods used in this research support the following conclusions: 1) In terms of rank order of asset deployment categories by firms, intangible assets appear to have a modest edge over tangible assets for deployment by value shop firms (architecctural and engineering design firms), but these emphases are not consistent among value chain-oriented (construction) firms. 2) Although pronounced differences were expected, there was little evidence of differences in rank order of asset category accumulation and deployment by firms (according to the Delphi panel) regardless of whether the firm was focused on continuity and longevity or (alternatively) short-term profit maximization. 3) Because of their ambidexterity in production logic, the expert panel had difficulty placing EPC (Engineer - Procure - Construct), design-build and integrated services firms in a single Stabell - Fjeldstad value logic category, and a new composite category was posited based on Delphi panel feedback.

Through the digital industry and economy, we find countless researches providing conceptual models aiming to depict digital technology adoption by different businesses. However, according to existing studies, we found that SMEs lack an e-business reference modelling framework that supports the design and adoption of digital-enabled business models. Therefore, we exploit an adaptive and technology-independent approach to propose an Enterprise Architecture (EA) based e-business reference modelling framework for SMEs in diverse business contexts. Our framework comprises mainly of three interrelated building blocks, starting with the 1) situational analysis to determine the motivating factors for change and barriers of the business environment; followed by SMEs profiling. The SMEs profiling embodies the 2) SMEs’ readiness depiction based on the existence of digital strategy, digital-value drivers’ catalogue, and business models proposals; and culminates with the 3) description of the implementation based on e-business architecture. In addition, a fourth building block is incorporated into the framework for eBusiness solutions architecture, selection, and deployment into the current SMEs' business context. In this study, we assume a practical approach, proposing and demonstrating the application of tools that support the conception of an SMEs´ e-business in the business context in all the different facets of our framework

Abstract:

An enterprise is a complex and changing entity, which is managed and maintained by humans. Enterprise architecture has been identified as an organisational strategy designed to assist enterprises with the understanding of complexity and the management of change. Acceptance, implementation and maintenance of enterprise architecture in organisations are complex and time-consuming. Work roles, responsibilities, common vocabulary, and buy-in are some of the cooperative human factors of stakeholders and participants and are believed to have an effect on the process of enterprise architecture acceptance in organisations. This study focused on identifying human factors affecting enterprise architecture acceptance and the question of how knowledge of these human factors can be used to assist organisations in the management of enterprise architecture acceptance. The research addressed two main research objectives: the development of a work-level-related model for enterprise architecture acceptance and a proposed method for assisting organisations with enterprise architecture acceptance. An initial set of human factors affecting enterprise architecture acceptance were identified through an exploratory study in one organisation. A study of existing literature was used to identify other human factors affecting enterprise architecture acceptance and to compile a more comprehensive list of human factors. The resulting comprehensive list of human factors was categorised into six constructed work-level-related human concerns and confirmed in more organisations. A work-level-related model for enterprise architecture acceptance was established based on the work-level-related human concerns and associated human factors. A method for organisational use and management of enterprise architecture acceptance based on the model was proposed. The result of the research is the Work-level acceptance framework for enterprise architecture (WoLAF for EA), which could contribute to understanding and managing the important aspect of human acceptance of enterprise architecture in organisations.

Thesis (MTech. degree in Software Development.)--Tshwane University of Technology, 2011
With regards to extending component-based and service-oriented system development approaches and solving current problems related to enterprise systems, this study will explore the requirements and challenges of current enterprise systems, and define an SCSD (Service-oriented Component-based System Development) framework which would provide all-round service-oriented component-based support for a complex application environment. The purpose of this study is to create a novel SCSD framework which combines the features of both component-based and service-oriented paradigms, as well as avoid the weaknesses of the existing service and component combination approaches. The SCSD framework combines the re-usability of the component-based paradigm and the flexibility of the service-oriented paradigm. Reusable SCSD-based components and services can reduce costs, shorten development time, and improve service quality when implemented effectively. The SCSD framework offers an alternative to older system development approaches, while it also provides a new solution in order to establish relationships between services and components for current enterprise systems.

Abstract:

Evidence of the interest in enterprise architecture (EA) is seen in the number of enterprise architecture frameworks (EAF) in existence. An EAF is responsible for the realisation of an EA, and therefore acts as a container for the terminology of EA. The lack of acceptance of terms and definitions, coupled with the phenomenon of the large number of EAFs, indicate a silo type understanding of what EA is, which leads to a lack of clarity in the conceptual foundations of EA. By following a design science research (DSR) approach, a conceptual artefact (an enterprise architectonic (EAt)) is created to address the lack of clarity in the conceptual foundations of EA thinking and practice. The EAt serves as a conceptual device to represent the fundamental understanding of EA in terms of concepts and their relationships. The content of the EAt is derived from applying a structured interpretation method (SIM) to three prominent EAFs (The Open Group Architecture Framework, the Department of Defense Architecture Framework and the Zachman Framework for Enterprise Architecture). The SIM’s results are an EA understanding that consists of an EA claim: EA is similar in intent to the enterprise as a worldview is to the world. It is supported by six EA propositions:  Proposition 1: EA’s underlying theoretical knowledge is in a pre-suppositional state.  Proposition 2: EA is a description of the structure of the systems of an enterprise.  Proposition 3: EA represents the enterprise in time-oriented architectures such as an as-is, to-be and has-been architecture.  Proposition 4: EA translates the values/strategy of the enterprise into operational systems appropriate to the information society.  Proposition 5: EA provides a means to manage decisions about the IT/IS management and implementation in the enterprise.  Proposition 6: EA captures a representation of the enterprise in the form of a model or set of models. The six EA propositions are analysed through the lens of Heidegger's equipment analysis, to produce a set of architectonic elements. These elements are arranged in the EAt to create a conceptual device to support the fundamental understanding of EA.

Dissertação de mestrado em Engenharia e Gestão de Sistemas de Informação
Enterprise Architecture is a guide to an organization‟s competitive fitness. It is the dynamic process of managing enterprise IT change through a planned transformation. This transformation is supported by templates, techniques and recommendations to start from the ground up. The aim of putting an enterprise through this process is to create or boost its competitive edge, but this cannot be accomplishment over the night. The most important assets to this process are the people, namely the architects with their end-to-end vision abilities. The line separating the several roles‟ level, especially the Enterprise, Solutions and domain architects is not clear to the industry and each project has its interpretation. The industry demands a new consultancy role, the Solutions Architect which is not older than 2005 (Alison 2007), to answer the requests for a role that is more than a specialist in a certain technology, the request is for a role with transverse business process knowledge. What this means is that Wipro‟s customers want this kind of consultants to be able to attend a certain topic, transversally to all business processes, no matter what tools will be used to accomplish the solution. One of the challenges is exactly to find a unified definition for this role, since Wipro‟s architects reveled to have very different, very correct perspectives on the topic, mainly due to their projects experience. With international, more influential customers, the maturity level of a service provider must evolve accordingly. Thus, Wipro seeks for an Enterprise Architecture that gives the support and confidence needed, and part of this challenge aims to map Wipro‟s practice to an industry leading framework and evolve their Architecture Competency Center to a more standards compliant state.
As arquitecturas organizacionais são um guia para o”bem-estar” organizacional. A construção deste tipo de arquitectura é um processo dinâmico de gerir a mudança tecnológica através de uma transformação planeada. Esta transformação é suportada por templates, técnicas e recomendações para começar a elaboração, qualquer que seja o estado actual. O objectivo de colocar uma organização no centro deste processo é o de criar ou aumentar a sua vantagem competitiva, mas este é um esforço não alcançável imediatamente. Os activos mais importantes neste processo são os profissionais, nomeadamente mas não só, os arquitectos com a sua visão “end-to-end”. A linha que separa os vários tipos de papéis não é clara, especialmente os papéis de Arquitecto Organizacional, de Soluções e dos vários domínios, principalmente pelas várias interpretações que os profissionais transportam das experiências em projectos muito distintos. A indústria pede claramente um novo tipo de papel de consultoria, o de Arquitecto de Soluções, sem expressão até 2005, de forma a responder aos pedidos de um papel que seja mais do que um especialista em determinada tecnologia, um papel que abarque o conhecimento transversal dos processos de negócio. Isto significa que os clientes da Wipro, empresa na qual este processo de dissertação foi desenvolvido, pedem que este tipo de consultores seja capaz de endereçar um determinado tópico, transversalmente a todos os processos de negócio, independentemente das tecnologias escolhidas para alcançar a solução. Um dos desafios propostos foi precisamente o de encontrar uma definição base para os arquitectos de soluções da Wipro, uma vez que estes possuem perspectivas distintas derivadas das experiências em projectos muito únicos. Com a maioria dos clientes de base internacional, o nível de maturidade de um prestador de serviços deve evoluir no mesmo sentido. Assim, a Wipro procura estabelecer uma Arquitectura Organizacional que forneça o suporte e a confiança necessárias para responder a questões metodológicas e a fundamentar as suas opções em standards, evoluindo assim o seu Centro de Competências de Arquitectura para um estado em concordância com um referencial comprovado e standards respeitados.

Abstract:

This dissertation focuses on the re-use of business process reference models, available in a business process model warehouse, to enable the definition of more comprehensive business requirements. It proposes a business process model warehouse framework to promote the re-use of multiple business process reference models and the flexible visualisation of business process models. The critical success factor for such a framework is that it should contribute to minimise to some extent the causes of inadequate business requirements. The proposed framework is based on an analogy with a data warehouse framework, consisting of the following components: usage of multiple business process reference models as source models, the conceptual design of a process to extract, load and transform multiple business process reference models into a repository, a description of repository functionality for managing enterprise architecture artefacts, and motivation of flexible visualisation of business process models to ensure more comprehensive business requirements.

Abstract:

O alinhamento entre os investimentos em Tecnologia da Informação (TI) e a definição ao dos objetivos de negócios e recorrentemente referido na literatura como uma tarefa primordial com impacto direto no lucro da organização. A Arquitetura Corporativa (EA) desempenha um papel importante na descrição das dependências entre um roteiro de migração ao de TI e as contra- partes de negócios, portanto, facilitando as decisões das partes interessadas. No entanto, as evidencias mostram que um número significativo de projetos de TI não consegue entregar os resultados desejados. Normalmente, as causas do fracasso incluem (i) a predominância de abordagens de gestão financeira de caixa preta que oferecem indicadores fracos, empheg, retorno sobre o investimento ou redução de custos, e (ii) não identificar os benefícios de negócios reais fornecidos pelo valor que pode ser gerado por um investimento em TI. Este artigo usa ArchiMate para propor um modelo para entender, projetar e gerenciar os benefícios do negocio. ArchiMate permite, entre outros, modelar camadas de negócios, aplicativos, tecnologia ou estratégia e agora é estendido com benefícios de negócios. Especificamente, é apresentado um ponto de vista da ArchiMate baseado no modelo Benefit Dependence Network (BDN). O objetivo dessa visão é apoiar os stakeholders que estão ao gerenciando os benefícios a serem alcançados por um investimento em TI. A solução conceitual e discutida e demonstrada no contexto do caso de uso da industria de televisão ao e vídeo de mídia. Posteriormente, as deficiências ontológicas desse modelo s ´ ao discutidas utilizando o método Wand Weber e por meio de entrevistas com especialistas.
The alignment between Information Technologies (IT) investments and business objectives definition is recurrently referred in the literature as a paramount task owning a direct impact on the organization’s profit. Enterprise Architecture (EA) plays an important role in describing the dependencies between an IT migration roadmap and business counterparts, therefore, facilitating the stakeholder’s decisions. However, evidence shows that a significant number of IT projects fail to deliver the desired outcomes. Usually, the failure causes are (i) the dominance of blackbox financial management approaches offering poor indicators, e.g., return-on-investment or cost reduction, and (ii) not identifying the real business benefits provided by the value that can be generated by an IT investment. This paper uses ArchiMate to propose a model to understand, design, and manage the business benefits. ArchiMate enables, among others, to model business, application, technology, or strategy layers and is now extended with business benefits. In specific, an ArchiMate viewpoint based on the Benefits Dependency Network (BDN) model is presented. The purpose of this viewpoint is to support the stakeholders that are managing the benefits to be achieved by an IT investment. The conceptual solution is argued and demonstrated in the context of the media video and television industry use case. Afterward, the ontological deficiencies of this model are discussed using the Wand Weber method and through interviews with experts.

In software engineering, object-oriented programming (OOP) language is used to develop software applications. To solve software development problems faced by two major “Variants” and “Complexity”, software developers re-use the “Variant” using components of the handing of the “Complexity”. The complexity in building software systems a direct consequence of the nature of real-world business problems, which are driven by changing requirements such as rapidly evolving technologies, multiple data sources, service-level agreements, interoperability, time to market, return on investment. This study describes how to design enterprise applications using a combination of frameworks and design patterns. This study uses a realistic business problem as the backdrop for the learning process of designing, building, and deploying an enterprise Java Web application using open source technologies.

In the age of the information and communication is so advanced, commercial activities have not only confined to the domestic. Enterprises must face the international business environment. Therefore, enterprises must be able to quickly adapt to changes in external environment. For the internal enterprise, the enterprise must be able to response to internal changes in strategy or business model, the enterprise application system must be able to adapt to changes in the enterprise. Therefore, how to make enterprise application system to quick response to rapidly changing demand is an important thing. Service-Oriented Architecture (SOA) can adapt to the need of the need of market quickly changing. Service-Oriented Architecture (SOA) can improve the flexibility and efficiency of development, and response immediately. Framework has the characteristics of reuse, framework will be able to increase the convenience of development on the enterprise application systems. Therefore, this study is how to make the framework able to meet the service-oriented architecture (SOA) standards. The system architecture is three-tier architecture. Using JSF framework, Spring framework, Hibernate framework to build business intelligence system, and using the prototype system to verify how framework can be on-demand and reach the standard of service-oriented architecture (SOA) to meet the information needs of enterprises.

Abstract:

An interpretive research approach will be used to describe and decompose UML diagrams into their respective building blocks. A top down approach will be used to determine views that are important to enterprises during the system development lifecycle. The importance of providing graphical representations to describe conceptual ideas will be stressed. A short history will be provided of the origins of UML as well as a description of the diagrams used. Since UML is a language and not a methodology a brief discussion regarding a methodology, the Rational Unified Process, will be covered. The Zachman framework will be used to present a two-dimensional (Columns and Rows) view of an enterprise together with a summary of what could be represented in the framework. The UML building blocks will be mapped within the Zachman framework together with possible reasons for the mapping. The paper will conclude by combining several views by different authors to represent artefacts within the Zachman framework and to show the strengths and weaknesses of the current UML version 1.5 and what organisations should be aware of when considering implementing UML.

Abstract:

A ISO 9001 e Arquiteturas Empresariais (AE), diferentes ferramentas de Governação com diferentes perspetivas, são dominantes entre os seus praticantes. Uma representação de uma ISO 9001 em ArchiMate pode potenciar ainda mais alinhamentos com outras frameworks representadas por AE e pode ajudar na obtenção de melhores resultados na implementação da Qualidade numa organização, obviando os custos e a duplicação de esforços. Esta tese propõe uma abordagem de integração entre a ISO 9001 e AE na perspetiva das AE ao propor um mapeamento de conceitos de ISO 9001 em EA pela definição de uma Arquitetura de Referência da ISO 9001 utilizando a linguagem de modelação do ArchiMate Dois objetivos são endereçados: a demonstração da capacidade de representar todos os requisitos da ISO 9001 em componentes de AE através do desenvolvimento da Arquitetura de Referência e reciprocamente a capacidade de desenvolver uma AE de um Sistema de Gestão da Qualidade (SGQ) teórico baseado na ISO 9001 com as componentes dessa Arquitetura de Referência. Adicionalmente, ao identificar e avaliar a existência das componentes da Arquitetura de Referência numa organização concreta, se estes não estão completamente mapeados, pode-se concluir a existência de um desvio relativamente ao referencial ISO 9001. Por ultimo, uma Arquitetura de Referência ArchiMate da ISO 9001 permite a partilha de conhecimento, a comunicação entre partes interessadas e contribui para a discussão e validação da ISO 9001 entre os utilizadores de Arquiteturas Empresariais.
ISO 9001 and Enterprise Architecture (EA), distinct governance approaches with different perspectives, are dominant between practitioners. An ISO 9001 ArchiMate representation can lead to further alignments with other EA represented frameworks and help obtain better results while avoiding costs and efforts duplication when implementing Quality. This thesis proposes an integration approach between ISO 9001 and EA from an EA perspective when proposes a mapping of ISO 9001 concepts to EA by defining an ISO 9001 Reference Architecture using the ArchiMate modeling language. Two goals are addressed: the ability to fully represent ISO 9001 Quality Management System (QMS) requirements using EA elements when developing the Reference Architecture, and reciprocally the ability to represent an ISO 9001 QMS EA, with the Reference Architecture components As a corollary, using the Reference Architecture in a specific organization, when evaluating the existence of each of these EA Reference Architecture elements, if they not occur or are not able to be mapped means a deviations against the standard ISO 9001. Finally, a formal ISO 9001 ArchiMate Reference Architecture allows knowledge sharing, stakeholder communication and contribute to ISO 9001 discussion and validation among AE practitioners.

Abstract:

The growing need for computer software in different sectors of activity, (health, agriculture, industries, education, aeronautic, science and telecommunication) together with the increasing reliance of the society as a whole on information technology, is placing a heavy and fast growing demand on complex and high quality software systems. In this regard, the anticipation has been on non-functional requirements (NFRs) engineering and formal methods. Despite their common objective, these techniques have in most cases evolved separately. NFRs engineering proceeds firstly, by deriving measures to evaluate the quality of the constructed software (product-oriented approach), and secondarily by improving the engineering process (process-oriented approach). With the ability to combine the analysis of both functional and non-functional requirements, Goal-Oriented Requirements Engineering (GORE) approaches have become de facto leading requirements engineering methods. They propose through refinement/operationalisation, means to satisfy NFRs encoded in softgoals at an early phase of software development. On the other side, formal methods have kept, so far, their promise to eliminate errors in software artefacts to produce high quality software products and are therefore particularly solicited for safety and mission critical systems for which a single error may cause great loss including human life. This thesis introduces the concept of Complementary Non-functional action (CNF-action) to extend the analysis and development of NFRs beyond the traditional goals/softgoals analysis, based on refinement/operationalisation, and to propagate the influence of NFRs to other software construction phases. Mechanisms are also developed to integrate the formal technique Z/Object-Z into the standardised User Requirements Notation (URN) to formalise GRL models describing functional and non-functional requirements, to propagate CNF-actions of the formalised NFRs to UCMs maps, to facilitate URN construction process and the quality of URN models.
