Full textAbstract:
Today’s fast-paced global economy has intensified the demand for manufacturing companies to make their products more quickly and with higher quality to meet heightened consumer expectations while reducing costs. This competitive environment requires small to medium enterprise’s (SMEs) to implement well-designed business processes and leverage information technology (IT), such as an Enterprise Resource Planning (ERP) system, within their facilities to become more agile, flexible, and integrated to meet changing market demands. Issues emerge when facility managers lack reliable data on performance and costs, which subsequently impairs even basic decisions for resource allocation or process improvement. Although the benefits of a successful ERP implementation in large firms are recognized, there is a general lack of empirical IT productivity literature focusing on SMEs.
This research is expected to contribute to a framework for performance measurement, providing facility decision-makers with important metrics for analyzing their firm’s ability to improve upon competitive priorities. Employing the Delphi process, key performance indicators (KPIs) including time, speed, quality, and cost, and corresponding performance measurement metrics, investigations are conducted between traditional manufacturing processes in SMEs and processes enhanced through ERP adoption. In this longitudinal case study, significant improvements are observed in production operations relative to time following ERP implementation including a reduction in the defect rate, total manufacturing cost, and scrap rate along with increases in on-time delivery and flexibility.

Raytheon Company, a leader in aerospace and defense, has experienced tremendous growth through mergers and acquisitions. In particular, the company's Space and Airborne Systems (SAS) business unit was largely formed through acquisitions of E-Systems and Texas Instruments and a merger with Hughes Aircraft Company. To assimilate the legacy organizations, Raytheon and SAS have undertaken great efforts to work as "One Company." One such example has been to strive for an enterprise sales and operations planning process. Five years ago, Raytheon Space and Airborne Systems (SAS) Operations leaders recognized the need to be more proactive in comprehending forecasted business and subsequent impacts to SAS' manufacturing network. As a result, Program Requirements and Operations Planning (PROP) was born to enable improved supply chain planning for factory labor and capital resources. Over time, the complexity of SAS' business has proven to be a challenge for PROP to achieve its intended objectives.- This thesis considers PROP as an enterprise rather than a process and proposes re-designing it using a holistic enterprise architecting framework including a thorough examination of the current state of PROP with respect to seven architectural views (strategy, policy/external factors, process, organization, knowledge, IT, and products/services). A future state PROP design is derived from the analysis and then validated against a detailed case study of the Army's Firefinder radar product line manufactured at Raytheon's Forest, Mississippi facility.

Full textAbstract:
The most important characteristic of enterprise architecture (EA) is that, it provides a holistic view of the enterprise. EA needs to consider about different aspects, views and viewpoints in an enterprise in order to make an enterprise more understandable and communicable to achieve organization goals and objectives. To do this matter EA needs to use different techniques or enterprise modeling methods to achieve different results of EA (documents/artifacts, models, goals/benefits). But many organization for building EA, use their own description techniques and conventions instead of using existing techniques or existing EMMs. They might use one technique which is not appropriate for modeling all aspects of EA. Our purpose is to discover the usefulness of EMMs in the process of construction EA to provide expected results of EA. We investigated about different EMMs to see its usefulness in producing which expected EA result. In order to increase the accuracy of the final results we investigated about different EMMs with respect to important EA aspects. To perform this study we have gone through a survey to validate EA important aspects and essential results of EA. Results of our study conducted based on both using literature review for studying about the usefulness of different EMMs and the results of our survey (EA aspects and results of EA). The results of this research show that Business, Organization, Technical, Information and Decision Making are five important aspects of EA; different EMMs can be used to produce several results of EA. We used table to illustrate the results of the study for each EA aspect separately. Our analysis revealed that the Decision Making and Information aspects of EA could get more help from EMMs compare to the other aspects, since the main focus of some of these methods such as GERAM, GRAI and GIM are mainly accumulated in these two aspects.

Full textAbstract:
At the present time, when enterprises have tendency for constant improvements, different tools are used to analyze current state of the business and to introduce organizational changes. Enterprise Modeling is one of these tools. Enterprise modeling can be used for different purposes: to restructure or standardize business processes, to develop business strategy, to capture best practices, etc. Evidently, enterprise models creation is resource-consuming job, since it requires variety of resources, for example labor, time and others. However, resources utilization is always aimed at result achievement, which originates the question of efficiency. There is a need to evaluate efficiency in the area of EM, which starts from defining a set of indicators to be checked. This work presents checklists of efficiency indicators for processes that EM can involve. For this purpose it identifies processes (so-called application areas of EMMs and enterprise models) that EM can involve. All of them are characterized with the help of two concepts: required resources and expected results. Formulated efficiency indicators can be used to analyze efficiency in the area of EM, particularly in application areas of EMMs and enterprise models.

The objective of this thesis is to depict the role of metrics in the evolving journey of enterprise transformation. To this end, three propositions are explored: (i) metrics and measurement systems drive transformation, (ii) employee engagement is a proxy to gauge transformation progress; and (iii) metric considerations enable enterprise transformation when systematically executed as part of a transformation roadmap. To explore this problem, the aerospace measurement community was consulted to help grasp a better understanding of the context in which transformation is currently defined and measured. Once the problem space was defined, the environment of doing research with the enterprise as the unit of analysis was described with the intent of exploring the role of metrics and transformation. In particular, the performance measurement literature helped identify tools and methods used to select metrics to enable decision making at the enterprise level. After this review, two case studies were performed, considering: (1) the implementation of a bottom-up measurement system to drive transformation and (2) the effect of a top-down corporate measurement system on the enterprise. The first case study revealed insights regarding the benefits and challenges of implementing measurement systems and highlighted the use of employee engagement as a proxy to measure enterprise transformation. In the second case study, contemporary measurement issues were discussed and mapped to an Eight Views of the Enterprise analysis to identify critical enterprise interactions.
(cont.) Ultimately, the Lean Advancement Initiative's Enterprise Transformation Roadmap was used as a method for depicting how performance measurement can help enable enterprise transformation. The implications of research in metrics for enterprise transformation span across thee areas: (1) the extensive literature reviews provide an academic contribution for performing enterprise and measurement research; (2) a common language and framework for exploring measurement problems is depicted for practitioners through the case study analysis; and (3) a connection between enterprise measurement and enterprise transformation is established to drive future transformation success.

The Department of Defense (DoD) presented a need to transform its Military Psychological Health Enterprise (MPHE) at multiple levels. It had been established that Enterprise Architecting would be used as an approach to perform the transformation but the way in which the multiple levels of the enterprise would be transformed had yet to be determined. The study began with an investigation into the current state of a low-level component of the MPHE. This investigation invoked Enterprise Architecting techniques to determine the as-is state of this low-level enterprise. Then, the results of the Enterprise Architecting analysis were combined with multilevel analysis techniques to create a framework that supported transformation of a complex, multilevel enterprise. It was determined that upon using Enterprise Architecting techniques to identify the dominant views of a low-level component of a multilevel Enterprise, the structure of the levels the enterprise as well as the interactions between the levels can be used to understand the impacts of decisions made at higher levels of the enterprise. In the specific case of the DoD MPHE, the dominant views were found to be Organization, Process, and Information. By investigating these dominant views in more depth, the ways in which its resources interacted while performing relevant tasks in this micro-level enterprise (Camp Lejeune MPHE) were determined. This information was transformed into objective data, which was then combined with the information about how the levels of the DoD MPHE interact to suggest a framework for modeling potential future states of the enterprise. This will support both the design and selection of a transformation plan for the enterprise. The descriptive application of the suggested framework provided in this thesis supports both the design and selection of a transformation plan for the enterprise.

Kumar, Sri K. "Tools for enterprises collaboration in virtual enterprises." Thesis, Loughborough University, 2013. https://dspace.lboro.ac.uk/2134/12512.
Full textAbstract:
Virtual Enterprise (VE) is an organizational collaboration concept which provides a competitive edge in the globalized business environment. The life cycle of a VE consists of four stages i.e. opportunity identification (Pre-Creation), partner selection (Creation), operation and dissolution. The success of VEs depends upon the efficient execution of their VE-lifecycles along with knowledge enhancement for the partner enterprises to facilitate the future formation of efficient VEs. This research aims to study the different issues which occur in the VE lifecycle and provides a platform for the formation of high performance enterprises and VEs. In the pre-creation stage, enterprises look for suitable partners to create their VE and to exploit a market opportunity. This phase requires explicit and implicit information extraction from enterprise data bases (ECOS-ontology) for the identification of suitable partners. A description logic (DL) based query system is developed to extract explicit and implicit information and to identify potential partners for the creation of the VE. In the creation phase, the identified partners are analysed using different risks paradigms and a cooperative game theoretic approach is used to develop a revenue sharing mechanism based on enterprises inputs and risk minimization for optimal partner selection. In the operation phases, interoperability remains a key issue for seamless transfer of knowledge information and data. DL-based ontology mapping is applied in this research to provide interoperability in the VE between enterprises with different domains of expertise. In the dissolution stage, knowledge acquired in the VE lifecycle needs to be disseminated among the enterprises to enhance their competitiveness. A DL-based ontology merging approach is provided to accommodate new knowledge with existing data bases with logical consistency. Finally, the proposed methodologies are validated using the case study. The results obtained in the case study illustrate the applicability and effectiveness of proposed methodologies in each stage of the VE life cycle.

Full textAbstract:
Contemporary enterprises depend to great extent on software systems. During the past decades the number of systems has been constantly increasing and these systems have become more integrated with one another. This has lead to a growing complexity in managing software systems and their environment. At the same time business environments today need to progress and change rapidly to keep up with evolving markets. As the business processes change, the systems need to be modified in order to continue supporting the processes. The complexity increase and growing demand for rapid change makes the management of enterprise systems a very important issue. In order to achieve effective and efficient management, it is essential to be able to analyze the system modifiability (i.e. estimate the future change cost). This is addressed in the thesis by employing architectural models. The contribution of this thesis is a method for software system modifiability analysis using enterprise architecture models. The contribution includes an enterprise architecture analysis formalism, a modifiability metamodel (i.e. a modeling language), and a method for creating metamodels. The proposed approach allows IT-decision makers to model and analyze change projects. By doing so, high-quality decision support regarding change project costs is received. This thesis is a composite thesis consisting of five papers and an introduction. Paper A evaluatesa number of analysis formalisms and proposes extended influence diagrams to be employed for enterprise architecture analysis. Paper B presents the first version of the modifiability metamodel. InPaper C, a method for creating enterprise architecture metamodels is proposed. This method aims to be general, i.e. can be employed for other IT-related quality analyses such as interoperability, security, and availability. The paper does however use modifiability as a running case. The second version of the modifiability metamodel for change project cost estimation is fully described in Paper D. Finally, Paper E validates the proposed method and metamodel by surveying 110 experts and studying 21 change projects at four large Nordic companies. The validation indicates that the method and metamodel are useful, contain the right set of elements and provide good estimation capabilities.QC20100716

Full textAbstract:
This research aimed at developing a research framework for the emerging field of enterprise systems engineering (ESE). The framework consists of an ESE definition, an ESE classification scheme, and an ESE process. This study views an enterprise as a system that creates value for its customers. Thus, developing the framework made use of system theory and IDEF methodologies. This study defined ESE as an engineering discipline that develops and applies systems theory and engineering techniques to specification, analysis, design, and implementation of an enterprise for its life cycle. The proposed ESE classification scheme breaks down an enterprise system into four elements. They are work, resources, decision, and information. Each enterprise element is specified with four system facets: strategy, competency, capacity, and structure. Each element-facet combination is subject to the engineering process of specification, analysis, design, and implementation, to achieve its pre-specified performance with respect to cost, time, quality, and benefit to the enterprise. This framework is intended for identifying research voids in the ESE discipline. It also helps to apply engineering and systems tools to this emerging field. It harnesses the relationships among various enterprise aspects and bridges the gap between engineering and management practices in an enterprise. The proposed ESE process is generic. It consists of a hierarchy of engineering activities presented in an IDEF0 model. Each activity is defined with its input, output, constraints, and mechanisms. The output of an ESE effort can be a partial or whole enterprise system design for its physical, managerial, and/or informational layers. The proposed ESE process is applicable to a new enterprise system design or an engineering change in an existing system. The long-term goal of this study aims at development of a scientific foundation for ESE research and development.

Dissertação para obtenção do Grau de Mestre em
Engenharia Electrotécnica e de ComputadoresWith the evolution of modern enterprises and the increasing market competitiveness, the creation of ecosystems with large amounts of data and knowledge generally needing to be exchanged electronically, is arising. However, this enterprise inter and intra-connectivity is suffering from interoperability issues. Not visible when it is effective, the lack of interoperability poses a series of challenging problems to the industrial community, which can reduce the envisaged efficiency and increase costs. Those problems are mostly caused by misinterpretations of data at the systems level, but problems at the organizational and human levels may pose equivalent difficulties. Existing research and technology provides several frameworks to assist the development of collaborative environments and enterprise networks with well-defined methods to facilitate interoperability. Nonetheless, the interoperability process is not guaranteed and is not easily sustainable, changing upon frequent market and requirement variations. For these reasons, there is a need for a testing methodology to assess the capability of enterprises to cooperate at a certain point in time. This dissertation proposes a methodology to assess that capability, with a corresponding framework to evaluate the interoperability process, applying eliminatory tests to assess the structure of the organizations, the conceptual models and their implementation. This work contributes to increase the chances enterprises have of interoperating effectively, and enables the adoption of extraordinary measures to improve their current interoperability situation.

Enterprise transformation is a dynamic process that builds upon and affects organizational processes. Organizational assessment plays critical role in planning and execution of enterprise transformation. It allows the assessment of an enterprise's current capabilities as well as for identification and prioritization of improvements needed to drive the enterprise transformation process. Despite the benefits that organizational assessment has to offer, many organizations fail to exploit them due to unfavorable organizational culture, unsatisfactory assessment processes or mismatch between assessment tool and broader transformation approach. This thesis focuses mainly on a model of organizational assessment and how it can be improved to better support enterprise transformation. We argue that the assessment process spans beyond performing the assessment itself. For the assessment to provide the expected benefit, organizations must first of all create an environment ensuring a clear understanding of the role assessment plays in the enterprise transformation process. To this end they must promote open and frequent discussion about the current state of the enterprise and future goals. The assessment process must be carefully planned to ensure it runs effectively and efficiently and that assessment results are accurate and reliable. Assessment results must be analyzed and turned into specific recommendations and action plans. At the same time, the assessment process itself must be evaluated and adjusted, if necessary, for the next assessment cycle. Based on literature review and case studies of five large aerospace companies, we recommend a five-phase assessment process model that includes mechanisms to change organizational behavior through pre-assessment phases. It also allows for adjustment of the assessment process itself based on the results and experience of participants so that it better suits the organization's needs and practices.

Data exchange between different information systems is a complex issue. Each system, designed for a specific purpose, is defined using a vocabulary of the specific business. While Web services allow interoperations and data communications between multiple systems, the clients of the services must understand the vocabulary of the targeting data resources to select services or to construct queries. In this thesis we explore an ontology-based approach to facilitate clients’ queries in the vocabulary of the clients’ own domain, and to automate the query processing. A governmental inter-department data query process has been used to illustrate the capability of the semantic approach.

It is becoming more and more common for developers to build enterprise applications on Spring framework or other other Java frameworks. While the developers are enjoying the convenient implementations of web frameworks, developers should pay attention to con- figuration deployment with metadata usage (i.e., Java annotations and XML deployment descriptors). Different formats of metadata can correspond to each other. Metadata usually exist in multiple files. Maintaining such metadata is challenging and time-consuming. Cur- rent compilers and research tools rarely inspect the XML files, not to say the corresponding relationship between Java annotations and XML files. To help developers ensure the quality of metadata, this work presents a Domain Specific Language, RSL, and its engine, MeEditor. RSL facilitates pattern definition for correct metadata usage. MeEditor can take in specified rules and check Java projects for any rule violations.
Developer can define rules with RSL considering the metadata usage. Then, developers can run RSL script with MeEditor. 9 rules were extracted from Spring specification and are written in RSL. To evaluate the effectiveness and correctness of MeEditor, we mined 180 plus 500 open-source projects from Github. To evaluate the effectiveness and usefulness of MeEditor, we conducted our evaluation by taking two steps. First, we evaluated the effec- tiveness of MeEditor by constructing a know ground truth data set. Based on experiments of ground truth data set, MeEditor can identified the metadata misuse.

Then, we applied MeEditor to the version histories of rule-adopted projects, which adopt the rule and is identified as correct project for latest version.

Full textAbstract:
A common challenge in organizations is a perception of that different languages are spoken among IT and other departments. Co-workers come from different background, have different knowledge base and sometimes even different objectives which can make an alignment more challenging. Enterprise Architecture (EA) can align IT investments with business directions and potentially solve issues regarding business-IT misalignments and bring value to organizations. Technical Debt (TD) is a well-established concept in software development and means that a solution that is “quick and dirty” is applied in order to earn time in short term and be able to provide a function in a system more quickly. This primitive implementation will at a later stage need to be corrected and rewritten, and the longer it takes, the more advanced, complex and time-consuming the correction will be. As EA has grown, major scientific and academic contributions have been developed. What is still missing is insight and ability to include a debt concept, which not only address TD but also business aspects. By adapting the TD concept in the EA domain, a new metaphor, providing a holistic perspective, has been proposed; Enterprise Architecture Debt (EAD). Up to the present debts for measuring EAD has been identified, but current research projects has not yet identified when a certain measure is to be considered of high or low quality. There is a need to develop a process for deriving such thresholds and identifying them. To be able to communicate the severity of an EAD to stakeholders, thresholds for EAD measures plays an important role. These thresholds will in the long term play a role in providing a tool for computer scientist working in organizations exploiting EA, and also contribute to current research within the field of IT-management and EA. By adopting a systematic process for defining expert driven thresholds a first version of a process for defining EAD thresholds could be presented and tested with domain experts. Five common opinions were detected, regarding the process, among the experts. The process could potentially facilitate useful communication and it was considered positive that it highlighted the context of the EAD. Also, that clearer process description and real-world EA model examples was needed, and that the moment of selecting membership function was unnecessary came up. Further, drivers for EAD thresholds and areas where it is perceived as important to have thresholds for EADs was a focus during the study. Cost and time, responsibility and engagement and context are perceived to be important drivers for EAD thresholds. While the business-it alignment and master data are seen as important areas. Also, context can play an important role when determine important areas.En vanlig utmaning inom organisationer är uppfattningen av att olika språka talas på IT-avdelningen och övriga avdelningar. Medarbetare kommer från olika bakgrund, har olika kunskapsbas och ibland till och med olika mål, vilket kan göra fastställandet av riktning mer utmanande. Enterprise Architecture (EA) kan säkerställa att IT investeringar och affärs direktiv går i samma riktning och kan därmed potentiellt lösa problem i anslutning till IT och övrig affärsverksamhet som uppstått på grund av detta och skapa värde till organisationen. Teknisk skuld är ett väletablerat koncept inom mjukvaruutveckling och syftar till att enlösning som är ”quick and dirty” tillämpas för att vinna tid på kort sikt och kunna tillämpa en funktionalitet i ett system snabbare. Denna primitiva implementation kommer vid senare tillfälle behöva korrigeras och skrivas om. Ju längre tid det tar desto mer avancerad, komplex och tidskrävande kommer ändringen att bli. I takt med att EA har vuxit har stora vetenskapliga och akademiska bidrag utvecklats. Vad som fortfarande saknas är insikt och förmåga att inkludera ett skuldkoncept som inte bara adresserar tekniks skuld utan även affärsaspekter. Genom att introducera konceptet teknisk skult i EA domänen har en ny metafor, som tillhandahåller ett helhetsperspektiv, föreslagits; Enterprise Architecture Debt (EA Debt). Fram tills idag har skulder för att mäta EA Debt blivit identifierade, men aktuella forskningsprojekt har ännu inte identifierat när en viss EA Debt är hög eller låg. Det finns ett behov av att utveckla en process för att härleda sådana gränsvärden och identifiera dem. För att kunna kommunicera all varlighetsgraden för en EA Debt till intressenter kan gränsvärden för EA Debt spela en viktig roll. Dessa gränsvärden kommer på lång sikt spela en roll när det kommer till att tillhandahålla verktyg för datavetare som arbetar i organisationer som tillämpar EA, och också bidra till aktuell forskning inom IT-förvaltning och EA. Genom att anta en systematisk process för att definiera expertdrivna gränsvärden har en första version av en process för att definiera EA Debt-gränsvärden kunnat presenteras och testas med domän-experter. Fem vanliga uppfattningar, gällande processen, kunde uppräckas bland experterna. Processens skulle också potentiellt kunna främja användbar kommunikation och det ansågs positivt att den belysta och tog hänsyn till kontext gällande EA Debt. Att tydligare processbeskrivning och verklighetstrogna EA-modeller som exempel behövdes samt att momentet där medlemsfunktion skulle väljas var onödigt kom också upp. Vidare så fokuserade studien på drivkrafter för att ta fram gränsvärden för EA Debt och områden där uppfattningen är att detta är viktigt. Kostnad och tid, ansvar och engagemang och kontext är uppfattade som viktiga drivkrafter när det kommer till gränsvärden för EA skuld, medan inriktningen för IT och övrig affärsverksamhet och basdata ses som viktiga områden. Även kontexten kan ha en viktig roll när det kommer till att avgöra vilka områden som är viktiga.

Full textAbstract:
The primary research aim of this dissertation is to identify the strategies that best meet the information retrieval needs as expressed in the "e-discovery" scenario. This task calls for a high-recall system that, in response to a request for all available relevant documents to a legal complaint, effectively prioritizes documents from an enterprise document collection in order of likelihood of relevance. High recall information retrieval strategies, such as those employed for e-discovery and patent or medical literature searches, reflect high costs when relevant documents are missed, but they also carry high document review costs.
Our approaches parallel the evaluation opportunities afforded by the TREC Legal Track. Within the ad hoc framework, we propose an approach that includes query field selection, techniques for mitigating OCR error, term weighting strategies, query language reduction, pseudo-relevance feedback using document metadata and terms extracted from documents, merging result sets, and biasing results to favor documents responsive to lawyer-negotiated queries. We conduct several experiments to identify effective parameters for each of these strategies.
Within the relevance feedback framework, we use an active learning approach informed by signals from collected prior relevance judgments and ranking data. We train a classifier to prioritize the unjudged documents retrieved using different ad hoc information retrieval techniques applied to the same topic. We demonstrate significant improvements over heuristic rank aggregation strategies when choosing from a relatively small pool of documents. With a larger pool of documents, we validate the effectiveness of the merging strategy as a means to increase recall, but that sparseness of judgment data prevents effective ranking by the classifier-based ranker.
We conclude our research by optimizing the classifier-based ranker and applying it to other high recall datasets. Our concluding experiments consider the potential benefits to be derived by modifying the merged runs using methods derived from social choice models. We find that this technique, Local Kemenization, is hampered by the large number of documents and the minimal number of contributing result sets to the ranked list. This two-stage approach to high-recall information retrieval tasks continues to offer a rich set of research questions for future research.

Full textAbstract:
In today's highly competitive, volatile and increasingly global manufacturing environment, manufacturing companies are increasingly aware of the need for agility and effectiveness at the supply-chain level, rather than simply at company level. Business Process Re-engineering and the resulting emphasis on core competence has influenced a move towards de-centralisation, flatter organisation structures and increased use of "outsourcing". It has been said that it is now supply-chain versus supply-chain and that this poses both opportunity and threat for SMEs. While some work has been done in relation to developing the concept of integrated supply-chains, relatively little has been published with respect to the concept of "Extended Enterprise (EE)", the "highest' 'level of inter-enterprise integration. This thesis provides a thorough review of literature with respect to supply-chain integration and Extended Enterprise. Current practice is evaluated on the basis of the literature review and an analysis of a questionnaire and some Case Study companies. A detailed description of Extended Enterprise is provided and a conceptual reference model is developed, with the aim of providing a strategic planning tool, which will help organisations to identify the extent to which they operate as part of an EE. The model is intended also to help organisations in their evolution towards more effective operation within EE. One of the key characteristics/enablers of EE is stated as the existence of an organisational structure, which supports the effective identification, rationalisation and deployment of core competence within an EE. An approach based upon the concept of a "Process Breakdown Structure" is introduced and is evaluated in the context of a Case Study Company.

Full textAbstract:
A Virtual Enterprise (VE) is a temporal alliance between two or more Small and Medium Enterprises (SMEs) geographically dispersed, which collaborate together in order to reach new business opportunities that would be unreachable in other ways. It is a business collaboration paradigm that aims at responding to the uncertainty and instability of the current global economy. VE requires support for electronic contract management, since electronic contracts formalize the agreements between the participating enterprises and coordinate their behavior. Although there is an abundance of previous work on electronic contracts, there is a lack of models and approaches related to VE contracts, which have an intrinsic dynamic and flexible nature, since they regulate independent behavior of diverse parties, and also aim at high automation in the formation and execution. This thesis aims at contributing to the VE contracting challenge. It includes a state of the art survey that identifies useful technologies and describes the most significant or relevant approaches. The state of the art survey identifies three main contracting issues: Contract specification, which determines the structure, content and performance of the contract; deontic logic norms, which represent the contractual interactions between the parties in terms of obligations, prohibitions and permissions; and ontology, which provides contracts with semantic meaning and allows interoperability. Furthermore, a simple XML-based VE Contract Representation Language and a Layered Contract Ontology, which provides common vocabulary to the contractual parties, are presented. Finally a VE scenario, including the associated contract, is described as an illustrative example.

Full textAbstract:
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.

This study is aimed at investigating the effect of mergers and acquisitions on the share

A sample of 79 mergers from 1999 to 2005 was used. The data was analysed using the
event study methodology and descriptive statistics. In addition, the paired t-test was also
conducted to test the significance of the results. The results were presented using graphs,
tables and charts.
The results showed that target companies obtained negative abnormal returns during the
announcement of mergers while acquiring companies on the other hand received positive
abnormal returns. The results imply that it can no longer be generalized that target
companies always win and acquiring companies lose during the merger activity.
On the other hand, the dividends for target companies increased significantly after the
merger, while the dividends for acquiring companies remained insignificantly negative
after the merger.Graduate School of Business Leadership

Background: Since the 1980s, the pace and dollar value of acquisitions in the US have grown at an astounding rate (Hitt, Sirower). The benefits from many of these acquisitions are elusive, with 60% of recent acquisitions showing negative return for the acquiring company (Hitt et. all, 5). Expected synergies are not realized despite the valiant efforts of the integration team who struggle with implementing the plans developed prior to deal close. Correlations can be drawn to the field of systems engineering, where specific processes and tools are employed to understand the interactions of various functional areas and avoid such implementation difficulties. Enterprise Architecting (EA) is one such framework that has shown promise in analyzing complex enterprises. Results: The thesis shows that all currently analyzed aspects of a potential acquisition are evaluated if the EA framework is used. It also shows that enough information is available prior to closing to use the EA framework to understand the potential enterprise. Further, it shows that the EA framework is flexible enough to accommodate the unique aspects of an acquisition analysis. Finally, the thesis shows a definite qualitative benefit from applying the EA framework.
(cont.) Conclusions: Despite the fact that one of the aspects of the hypothesis was not met, EA is still a valid and beneficial framework to apply to the acquisition process. It provides a sound process framework that should be used to design and implement robust acquisition analysis processes. This will enable greater process efficiency, quality, and consistency.

OEMinc's new business model is a dramatic departure from that used in the past. The company has moved steadily upstream in the supply chain, leaving more and more of the manufacturing effort to suppliers. Literature shows that extraordinary productivity gains in the production network, or value chain, are possible when companies are willing to collaborate in unique ways, often achieving competitive advantage by sharing knowledge, research and assets. For its newest product, Excelsior, OEMinc has moved to an extended enterprise model involving dozens of Partners. Approximately half are Component Partners (CPs), who supply systems and components. The remainder are Assembly Partner's (APs), who integrate these components into sub-assemblies. Many components are purchased by OEMinc and drop-shipped by CPs to APs, then installed in subassemblies. For the purposes of this analysis, Critical Safety Inventory is defined as inventory held at a site that buffers against disruptions in quality or upstream delivery and is not needed for production at that time.
(cont.) More specifically, the need for CSI is driven by the following: *variability in delivery time, resulting in late parts at the AP site or at OEMinc; *part non-conformances, which result in parts being unavailable for installation; and/or *part damage upon installation. The challenge OEMinc faces, which this project attempts to address, is: "How can OEMinc mitigate supply chain risk in the context of reduced information and control?" This project focuses on inventory management as a tool for mitigating risk. Therefore, the project definition has been further defined as follows: To develop an effective safety inventory policy for OEMinc-owned, drop-shipped components within the Excelsior Supply Chain, with the goal of supporting production, reducing inventory cost, and enabling continuous improvement. As outlined above, OEMinc's move to the extended enterprise business model is a significant step towards its vision of being a large-scale systems integrator. The success of this transition is important for OEMinc's long-term future, in addition to being an enabler for the Excelsior. The following approach was used: 1) Case Studies: Components were selected based on characteristics that bracketed the types of issues that might be seen in the supply chain at OEMinc.
(cont.) It was expected that examination of these supply chains would reveal particular issues representative of a wider selection of components. 2) Simulation analysis: A generic simulation model was created for components under the Excelsior Business model. The simulation was used to determine how many shipsets of inventory should be held at the AP site for a varying lead times, expedite lead times and risks of non-conformance. 3) Benchmarking: Representatives of peer companies were interviewed and site visits were conducted to gather information on how they manage their relationships with partner suppliers, with special attention paid to inventory management, partner management, incentives and data exchange. 4) Metrics Analysis: OEMinc's existing metrics system was assessed to determine what changes might be made given the business model shift for the Excelsior program. 5) Implementation: Based on the results of the preceding steps, a set of guidelines was developed for Partners to reach the desired state with respect to CSI management. Using a Systems Dynamics framework, the supply chain was analyzed to determine what incentives should be applied to encourage the desired supplier behavior.

Full textAbstract:
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.

Full textAbstract:
Enterprises are growing in complexity due to numerous interactions within and outside the enterprise. Enterprise modeling addresses this issue of complexity by helping to structure it. A review of the literature indicates several issues in the field of enterprise modeling need to be addressed. First, the terms related to enterprise modeling have numerous definitions, each one focusing on different aspects. These definitions are analyzed and a comprehensive definition is provided. Next, enterprise modeling methodologies and enterprise modeling frameworks in the literature focus on different views when modeling an enterprise, thus making it difficult for an enterprise to choose the framework that best fits their needs. In order to resolve this, an enterprise modeling framework is designed that attempts to incorporate all of the views of an enterprise. This framework is then extended, by taking into account various models and functionalities provided in enterprise modeling software packages.

Full textAbstract:
The business processes of manufacturing enterprises have to be dynamic, especially when highly customised products are manufactured or different projects run simultaneously. Another trend in contemporary manufacturing is the necessity for co-operation between geographically dispersed teams. This research presents a new method for modelling business processes enabling co-ordination of dynamic workflows. This thesis focuses first on Business Process Modelling (BPM) techniques and outlines the limitations of the existing methodologies. Similarly, an overview of Enterprise Collaborative Portals (ECP) is conducted and a method for collaborative authoring of dynamic workflows is discussed. Next, the thesis introduces the concept of business process models with feedback based on the Product/process (P/p) methodology. An extension to this methodology, validated through a case study, is developed to overcome some of its limitations. The performance of the proposed extension is analysed and compared with that of the Unified Modelling Language (UML) and its advantages are highlighted. The case study used to demonstrate the capabilities of the proposed approach involves the development of a golf training device prototype using Rapid Prototyping technology. The proposed process modelling methodology is validated in PTC Windchill EIMS, which also serves as a platform for the implementation of the enterprise collaborative portal. The thesis also proposes a benchmarking method for business processes based on the work of Spendolini and the extended P/p methodology. Benchmarking factors are identified and the proposed benchmarking methodology is validated with an example. The benefits of the proposed benchmarking methodology are outlined. Finally, a method for modelling business processes enabling co-ordination of dynamic workflows is presented. The same case study is used to illustrate the algorithm for collaborative authoring of the business process model. As a platform for the implementation of the proposed method, an object-oriented architecture is adopted.

This thesis proposes a technology strategy that is formulated to serve as the foundation for a holistic. global knowledge networking strategy for multinational enterprises (MNEs). This thesis is framed in the context of the increasing salience of knowledge for all enterprises, everywhere, today. The uncertainties of the marketplace, global e-business opportunities born of the Internet revolution, and the paradigmatic shifts in thought on organizational design have amplified the demand for the right knowledge of the right kind at the right time. The multi-dimensional nature of knowledge and the complexities of enterprise activities are compounded by the fact that enterprises today are increasingly globalized and seeking to globally expand its activities. The capabilities to acquire quality-controlled knowledge within the necessary time-horizons, and the capabilities to leverage and diffuse acquired knowledge throughout the organization have become critical. However, the mechanisms by which to perform and enable these functions are not strategically integrated across the organization, and on a global basis. This thesis focuses on the knowledge network as a mechanism and as a process by which to coordinate innovation and learning for enterprises and enterprise-value-networks on a global basis. While knowledge networks have been formed in both non-profit and for-profit sectors, this thesis will be concerned solely with knowledge networks for businesses. Knowledge networks can be analyzed into technology and human elements, but often there is no coordinating strategy that synthesizes both elements into integrative solutions that can capture the value of knowledge for the enterprise. The hypothesis . guiding this thesis is that existing models of knowledge networking are not sufficiently holistic. and proposes an integrated knowledge networking strategy that leverages both technology infrastructure and human competencies in meeting organizational knowledge requirements. The emergent nature of strategically initiated knowledge networks in business can adapt knowledge networking solutions that have been developed in the non-profit sector. One such framework for knowledge networking from the non-profit sector is the GSSD (Global System for Sustainable Development) initiative, developed in MIT with partners in academic institutions around the world, is one such methodology that aims to facilitate knowledge flows and knowledge sharing on a global scale. This thesis (a) develops a technology strategy that adapts the GSSD framework for enterprises that operate on a global scale, (b) illustrates its conceptual feasibility by proposing several designs for GSSD-E, or GSSD for the enterprise, and (c) applies the designs to a test case. The test case is a conceptual implementation of the GSSD-E design for Sony Environmental Management Systems. The thesis concludes by suggesting further possible directions in researching GSSD-E possibilities.

Full textAbstract:
Context: Enterprise Cloud Computing (or Enterprise Clouds) is using the Cloud Computing services by a large-scale organisation to migrate its existing IT services or use new Cloud based services. There are many issues and challenges that are barrier to the adoption of Enterprise Clouds. The adoption challenges have to be addressed for better assimilation of Cloud based services within the organisation. Objective: The aim of this research was to develop an assessment model for adoption of Enterprise Clouds. Method: Key challenges reported as barrier in adoption of Cloud Computing were identified from literature using the Systematic Literature Review methodology. A survey research was carried out to elicit industrial approaches and practices from Cloud Computing experts that help in overcoming the key challenges. Both key challenges and practices were used in formulating the assessment model. Results: The results have highlighted that key challenges in the adoption of Enterprise Clouds are security & reliability concerns, resistance to change, vendor lock-in issues, data privacy and difficulties in application and service migration. The industrial practices to overcome these challenges are: planning and executing pilot project, assessment of IT needs, use of open source APIs, involvement of legal team in vendor selection, identification of the processes to change, involvement of senior executive as change champion, using vendor partners to support application/service migration to Cloud Computing and creating employee awareness about Cloud Computing services. Conclusion: Using the key challenges and practices, the assessment model was developed that assesses an organisation’s readiness to adopt Enterprise Clouds. The model measures the readiness in four dimensions: technical, legal & compliance, IT capabilities and end user readiness for the adoption of Enterprise Clouds. The model’s result can help the organisation in overcoming the adoption challenges for successful assimilation of newly deployed or migrated IT services on Enterprise Clouds.

La plupart des projets de développement logiciel actuel dépendent de l'utilisation des solutions existantes pour gagner du temps et réduire les coûts de développement. Pour atteindre cet objectif, les entreprises doivent tirer parti des fonctionnalités offertes par les services techniques ou les interfaces de programmation applicatives exposées par les solutions existantes. La collecte et la qualification de ces composants ou services techniques permet de les réutiliser directement ou par orchestration. L'objectif de ce travail est double. Tout d'abord, nous visons la conception d'un conteneur de capacités logicielles qui offre une vision plus large des solutions applicatives internes ou externes d'une organisation. Le deuxième objectif est de définir un modèle d'exploitation de ces profils de capacités logicielles en adéquation avec l'ingénierie des besoins et l'architecture d'entreprise, afin de combler l'écart entre les objectifs des parties prenantes et ce qui peut être fourni comme solution pratique. Cependant, pour atteindre les objectifs susmentionnés, il y a de nombreux défis à relever pour gérer la complexité de l'exploitation des profils de capacités logicielles internes ou externes, afin de sélectionner les meilleurs composants candidats pour servir d'éléments constitutifs dans un nouveau système. Parmi ces défis, on peut citer l'identification des connaissances architecturales pour l'évaluation et la réutilisation des composants techniques, ou l'alignement des besoins et des artefacts d'architecture dans un cycle d'ingénierie pour la consolidation et le raffinement des exigences, afin de faciliter la découverte et la réutilisation des solutions applicatives existantes. A cet effet, nous définissons un Framework offrant un processus de qualification qui permet de recueillir les exigences initiales utilisées pour guider le développement des applications existantes et des services techniques exposés. Le processus de qualification est4basé sur un profil de capacité d'architecture d'entreprise proposé et de son ontologie associée. Cette dernière est utile pour spécifier formellement le profil de capacité produit qui offre une qualification couvrant les aspects organisationnels, opérationnels et techniques des applications orientées services. De plus, une méthodologie d'exploitation du conteneur conçu pour agréger ces profiles est proposée avec le Framework et basée sur l'alignement du processus d'ingénierie des besoins avec une méthode de développement d'architecture. Ces derniers évoluent ensemble pour étudier la plus grande compatibilité fonctionnelle et technique des fonctionnalités souhaitées et des contraintes associées, pour répondre aux besoins des utilisateurs finaux et réutiliser efficacement les solutions qualifiées.Notre contribution vise à améliorer l'évaluation, la découverte et la réutilisation des applications et des services techniques associés. Par ailleurs, l'originalité de ce travail de recherche consiste à mettre à niveau la recherche sur la consommation et l'orchestration des services au niveau des besoins des utilisateurs finaux, afin d'accélérer et de faciliter le développement d'applications métier futures. Une implémentation du Framework ainsi qu'une étude de cas industriels sont proposés pour valider et démontrer l'efficacité de cette approcheMost of today's software development projects depend on the usage of existing solutions to save time and development cost. To achieve this goal, companies should take advantage of the features provided by services or application programming interfaces exposed by existing solutions. Collecting and qualifying IT components and services helps to reuse them directly or via orchestration. The goal of this work is twofold. First, we target the design of a software capability container that provides a broader view of an organization’s internal and external software. The second objective is to define an exploitation model of the software capability profiles in line with requirements engineering and enterprise architecture, to fill the gap between the goals of the stakeholders and what can be delivered as a practical solution. However, to achieve the above-stated objectives, there are many challenges to manage the complexity of the exploitation of internal or external’s software capability profiles, to select the best candidate components to act as a building blocks in a new system. Among those challenges, one can mention the identification of architectural artifacts for the evaluation and reuse of software components. Adding to this challenge, the alignment of requirements and architectural artifacts in engineering cycle for requirements consolidation and refinement to facilitate the discovery and reuse of existing solutions.For this purpose, we define a Framework offering a qualification process that helps to retrieve and gather initial requirements used to guide the development of existing software and related services. The qualification process is based on a proposed Enterprise Architecture Capability Profile and its associated ontology. This latter is useful to formally specify and encode the produced capability2profile that offers a qualification and covers business, operational and technical aspects for service-oriented software. Furthermore, an exploitation methodology of the designed container is proposed along with the Framework and based on the alignment of requirements engineering process with an architecture development method. These latter evolve together to investigate the highest functional and technical compatibility of the desired functionalities and related constraints, to respond to end-user’s requirements and efficiently reuse the qualified solutions.Our contribution aims to improve the evaluation, discovery, and reuse of existing software and related services. Besides, the originality of this research work consists in upgrading research on services consumption and orchestration to the level of end-users’ requirements, mapped with advanced service assets as an enabler for accelerating business application development. An implementation of the Framework along with an industrial case study are proposed to validate and demonstrate the effectiveness of this approach

The purpose of this single case study was to explore enterprise risk management strategies that nonprofit business leaders used to maintain and improve organizational sustainability. The study population included 3 executive leaders from a rehabilitation and social services nonprofit agency located in the northeastern United States. The Committee of Sponsoring Organizations integrated enterprise risk management framework was the conceptual lens used in this study. Data were collected through semistructured interviews with the 3 executive leaders of the client organization and review of internal, external, and publicly available documents. Data and information from documents and interviews were manually coded. Findings were validated through data triangulation and member checking to help ensure accuracy, consistency, and credibility. Several overarching themes emerged from data analysis related to managing risk for sustainability: a commitment to culture and the mission, vision and values; operational efficiencies to build a financially strong organization; engagement of executive staff and board members; and addressing staffing needs for ongoing operations to meet client needs. Findings from this study might contribute to positive social change by providing nonprofit leaders with enterprise risk management strategies and processes to maintain and improve organizational performance, thereby helping to ensure leaders’ ability to serve and improve their communities.

Full textAbstract:
Access control (AC) is a necessary defense against a large variety of security attacks on the resources of distributed enterprise applications. However, to be effective, AC in some application domains has to be fine-grain, support the use of application-specific factors in authorization decisions, as well as consistently and reliably enforce organization-wide authorization policies across enterprise applications. Because the existing middleware technologies do not provide a complete solution, application developers resort to embedding AC functionality in application systems. This coupling of AC functionality with application logic causes significant problems including tremendously difficult, costly and error prone development, integration, and overall ownership of application software. The way AC for application systems is engineered needs to be changed.
In this dissertation, we propose an architectural approach for engineering AC mechanisms to address the above problems. First, we develop a framework for implementing the role-based access control (RBAC) model using AC mechanisms provided by CORBA Security. For those application domains where the granularity of CORBA controls and the expressiveness of RBAC model suffice, our framework addresses the stated problem.
In the second and main part of our approach, we propose an architecture for an authorization service, RAD, to address the problem of controlling access to distributed application resources, when the granularity and support for complex policies by middleware AC mechanisms are inadequate. Applying this architecture, we developed a CORBA-based application authorization service (CAAS). Using CAAS, we studied the main properties of the architecture and showed how they can be substantiated by employing CORBA and Java technologies. Our approach enables a wide-ranging solution for controlling the resources of distributed enterprise applications.

Dissertation presented at Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa to obtain the Master degree in Electrical Engineering and Computer ScienceIn the actual competitive world, doing business globally has become critical to the survival of most enterprises. It is becoming each day more and more difficult for small enterprises to grow by operating alone in the market. Hence, most companies started feeling the need for joining collaborative environments becoming easier to manage their products and services, and where they can offer better products with low production costs. To achieve this, enterprises require the establishment of cooperation agreements among each other with the idea of expanding their business networks. Consequently there is a demand for intelligent solutions capable of reinforcing partnerships and collaborations between enterprises, organised groups or singular people. However, due to the worldwide diversity of communities, a high number of knowledge representation elements, such as ontologies, which are not semantically coincident, have appeared representing the same segment of reality. Even operating in the same domain, enterprises do not understand each other, making the communication among various systems parties more difficult and sometimes impracticable. This dissertation responds to the needs identified above, proposing a collaborative methodology for ontology building, enriched with qualitative information collection methods, to effectively improve the approach to elicit knowledge from business domain experts, towards interoperable intelligent systems. This methodology allows different individuals from enterprises or organisations working on the same field or area, to join a collaborative environment for building a common ontology specific to their ―Domain of Discourse‖. To accomplish this, several steps are taken including terms and definitions gathering, glossary and thesaurus building, and ontology mappings

In Scotland, current policy aims to produce work ready young people with relevant enterprise and employment skills. However, many are caught in a repetitive cycle of short term work placements with large numbers of young people still not at work or in education. Accordingly, this study was concerned with social capital in respect of young people’s outcomes from engaging with a youth work project, that was designed to encourage enterprise and employability skills. Using qualitative data drawn from a single site case study, this research develops an understanding of the extent to which different forms of social capital influenced young people’s outcomes. The thesis sets out a theoretical position that draws from Archer’s understanding of critical realism and social capital theory based on the works of Putnam, Coleman and Bourdieu. This approach suggests that the complex interactions between social structures, identities, material resources and cultural forms, enable or inhibit the emergence of social capital practices. An action research approach was applied and empirical work was based on observations and reflections of young people participating in an enterprise challenge. Data were collected via questionnaires, professional discussions and the observations and analysis of relevant documents. Overall findings illustrate the emergence of bonding, bridging and linking social capital in addition to identity, economic and cultural capital developments. However, changes within social structure were the hardest to detect. Whilst there are indicators of young people’s improved outcomes, findings suggest that conditioned socio-cultural stereotypes in respect of gender and class may be limiting opportunities. Shared reflexive practices and linking social capital may however provide opportunities to disrupt, and create new pathways, but should be treated with caution. Youth workers can develop and extend the reach of young people’s social capital practices and the thesis concludes by presenting a set of general recommendations that might serve to facilitate change.

Full textAbstract:
Enterprise Resource Planning (ERP) systems are software programs designed to integrate the functional requirements, and operational information needs of a business. Pressures of competition and entry standards for participation in major manufacturing supply chains are creating greater demand for small business ERP systems. The proliferation of new offerings of ERP systems introduces complexity to the selection process to identify the right ERP business software for a small and medium-sized enterprise (SME). The selection of an ERP system is a process in which a faulty conclusion poses a significant risk of failure to SME’s. The literature reveals that there are still very high failure rates in ERP implementation, and that faulty selection processes contribute to this failure rate. However, the literature is devoid of a systematic methodology for the selection process for an ERP system by SME’s. This study provides a methodological approach to selecting the right ERP system for a small or medium-sized enterprise. The study employs Thomann’s meta-methodology for methodology development; a survey of SME’s is conducted to inform the development of the methodology, and a case study is employed to test, and revise the new methodology. The study shows that a rigorously developed, effective methodology that includes benchmarking experiences has been developed and successfully employed. It is verified that the methodology may be applied to the domain of users it was developed to serve, and that the test results are validated by expert users and stakeholders. Future research should investigate in greater detail the application of meta-methodologies to supplier selection and evaluation processes for services and software; additional research into the purchasing practices of small firms is clearly needed.

Full textAbstract:
People around the world who are working in companies and organisations need to collaborate, and in their collaboration use information managed by different information systems. The requirements of information systems to be interoperable are therefore apparant. While the technical problems, of communicating or sharing information between different information systems, have become less difficult to solve, the attention has turned to other aspects of interoperability. Such aspects concern the bussiness processes, the knowledge, the syntax and the semantics that involves the information managed by information systems. Enterprise modelling is widely used to achieve integration solutions within enterprises and is a research area both for the integration wihin an enterprise (company or organisation) and the integration between several different enterprises. Enterprise modelling takes into account several of the aspects, mentioned as important for interoperability, in the models that are created. This thesis describes a research which has resulted in the connector view concept. The main contribution with this framework comprises a model structure and an approach, for performing the modelling of the collaboration between several partners in an extended enterprise. The purpose of the enterprise models thus created, by using the connector view concept, is to find solutions to interoperability problems, that exist in the collaboration between several enterprises.

B2B eBusiness model is viewed as one of the most promising business strategies in 21st century. The essence of B2B eBusiness is enterprise integration which is in turn dependent on the integration of business processes, application systems and information among enterprises. The development of a flexible and dynamic framework for enterprise application integration to enhance enterprise integration has therefore become one of the most important tasks in industry. Due to the complicated relationships and heavy interactions with partners, the B2B eBusiness model will bring conglomerate enterprises opportunities as well as challenges in developing an enterprise application integration framework. The objective of this research is to design an enterprise application integration framework to facilitate the integration of a conglomerate enterprise and thus realize its B2B eBusiness operations. To achieve the objective, the focus of this research is three-fold: 1) design of a B2B business model for conglomerate enterprises through analyzing its organizational structure and inter and intra-enterprise interactions, 2) design of a functional framework for enterprise application integration based on the proposed B2B business model, and 3) design of an architecture of a service-based enterprise integration platform based on the proposed framework using web-service technology. This research provides the blueprint of conglomerate enterprises’ information integration architecture that can help achieve the dynamic enterprise alliance and obtain closer enterprise partnership so as to promote business effectiveness of conglomerate enterprise and its entire supply chain.

Enterprise Information Portal（EIP） is the basic indicator of e-enterprise level, it can distribute information and attract customers via internet. In 2005, a survey of the construction e-enterprise shows that construction EIPs were still not enough. Therefore, assisting construction small and medium enterprises（SMEs） to build their own EIP has become to an important action. In this research, the main information items with construction EIP is found, then the web-based construction EIP assistant system （CEIPA） is developed by using ASP.NET. This system is planning for three kinds of users, there are system administrator, EIP manager and EIP viewer. Construction SME can use this system to build their own EIP and setup the configuration, Theme and Information Items of EIP. CEIPA also can be the asistant tool for government to pushing e-construction policy.
