The ever-increasing demand for access to the world's major commercial airports combined with capacity constraints at many of these airports have led to increasing air traffic congestion. In particular, the scarcity of airside (take-off and landing) capacity at these airports has not been appropriately priced, leading to excessive demand as in the Tragedy of the Commons. Congestion pricing, as a classical economic approach to the efficient allocation of constrained transportation infrastructure capacity, has a long history of theoretical development. However, its application in the airport setting must deal with a set of important differences from the classical urban roadway setting. These differences have eluded the attention of researchers until very recently. They stem from the following set of complications: i) the peak and off-peak periods at congested airports are often less distinguishable than in the urban transport context; ii) airlines are a dominant intermediary between an airport's capacity and passengers as the end-users of that capacity; and iii) airlines operate groups of flights, as distinct from the atomistic behaviour of individual commuters. To address these complications, an analytical model is developed to explore the impact of congestion pricing at airports and understand potential airline responses under a range of assumptions about the market's structure. Through a set of numerical experiments, carried out with the help of a probabilistic queuing model, we compare the economic benefits resulting from adopting fine versus coarse congestion tolls for the cases of markets with symmetric and asymmetric carriers. Given sustained demand for access to an airport and reasonably elastic responses in terms of frequency adjustments,
(cont.) the benefits to carriers of instituting congestion pricing generally exceed the amount of tolls collected. While a system of fine or graduated tolls is suited for all airports, systems of coarse or uniform tolls, which can be implemented more easily, are applicable only at airports with fairly symmetric carriers that hold approximately equal frequency shares. In addition to congestion pricing, slot lease auctions can also be an effective means for promoting an economically efficient use of scarce airport capacity. In practice, the impact of slot lease auctions is similar to that of coarse tolling. Slot auctions are therefore applicable, in pure form, at airports with symmetric carriers. At these airports, a market-based demand management policy can comprise both congestion pricing and slot lease auctions. With respect to implementation, simultaneously ascending auctions recently used in the context of allocating electromagnetic spectra can be appropriately adopted to airports. A lump-sum subsidy can be used to promote specific socially desirable goals in the allocation of scarce airport capacity. Several airport authorities around the world, currently using purely administrative or hybrid forms of demand management, have developed sophisticated techniques for defining and managing their constrained airport capacity. Some of these techniques can be useful in developing market-based demand management policies. As an interesting case study, the experience of New York's LaGuardia Airport (LGA) ...

Technology development is hard for management to understand and hard for practitioners to explain, however it is an essential component of innovation. While there are standard and predictable processes for product development, many of these techniques don't apply well to technology development. Are there common processes for technology development that can make it predictable, or is it unpredictable like basic research and invention? In this thesis, after building a foundation by looking at product development processes, I survey some of the literature on technology development processes and compare them to a handful of case studies from a variety of industries. I then summarize the observations from the cases and build a generic model for technology development that can be used to provide insights into how to monitor and manage technology projects. One of the observations from the product development literature is that looping and iteration is problematic for establishing accurate schedules which becomes one of the fundamental disconnects between management and engineering. Technologists rely heavily on iteration as a tool for gaining knowledge and combined with other risks, technology development may appear "out of control". To mitigate these risks, technologists have developed a variety of approaches including: building a series of prototypes of increasing fidelity and using them as a form of communication, simultaneously developing multiple technologies as a hedge against failure or predicting and developing technologies they think will be needed outside of formal channels. Finally, I use my model to provide some insights as to how management can understand technology development projects. This gives technologists and non-technical managers a common ground for communication.

Ladd, Dana Forrest. "Extending Two-Dimensional Knowledge Management System Theory with Organizational Activity Systems' Workflow Dynamics." ScholarWorks, 2016. https://scholarworks.waldenu.edu/dissertations/3305.
Full textAbstract:
Between 2005 and 2010 and across 48 countries, including the United States, an increasing positive correlation emerged between national intellectual capital and gross domestic product per capita. The problem remains organizations operating with increasingly complex knowledge networks often lose intellectual capital resulting from ineffective knowledge management practices. The purpose of this study was to provide management opportunities to reduce intellectual capital loss. The first research question addressed how an enhanced intelligent, complex, and adaptive system (ICAS) model could clarify management's understanding of organizational knowledge transfer. The second research question addressed how interdisciplinary theory could become more meaningfully infused to enhance management practices of the organization's knowledge ecosystem. The nature of this study was phenomenological to gain deeper understanding of individual experiences related to knowledge flow phenomena. Data were collected from a single historical research dataset containing 11 subject interviews and analyzed using Moustakas' heuristic framework. Original interviews were collected in 2012 during research within a military unit, included in this study based on theme alignment. Organizational, knowledge management, emergent systems, and cognition theories were synthesized to enhance understandings of emergent ICAS forces. Individuals create unique ICAS flow emergent force dynamics in relation to micro- and macro-meso sensemaking and sensegiving. Findings indicated individual knowledge work significantly shapes emergent ICAS flow dynamics. Collectively enhancing knowledge stewardship over time could foster positive social change by improving national welfare.

Haustein, E. "Management control systems in innovation companies : a contingency theory study." Thesis, University of the West of England, Bristol, 2014. http://eprints.uwe.ac.uk/23122/.
Full textAbstract:
Past research has traditionally argued that management control systems (MCS) may present a hindrance to corporate flexibility and creativity. The study’s overall research aim is to explore the contingency factors that influence the intensity of use of MCS in innovation companies. This thesis builds upon existing management control theory, mostly focused on R&D, product development and innovation settings, extended by field observations to identify factors that may influence the intensity of use of MCS categories in innovation companies. The objects of control paradigm, distinguishing between direct and indirect categories of control, is mobilized to test the consequent theoretical model of the impact of external, organisational and innovation related contingency factors on MCS. The model predicts mixed influences on two direct control categories, results control and action control, but stresses the importance of two indirect categories, personnel control and cultural control. Empirical evidence was then collected from a cross-sectional survey of 578 German enterprises in innovation clusters. Statistical analyses, applying partial least squares structural equation modeling using SmartPLS, identify several variables as influential factors for the use of MCS in innovation companies. The most important factors are environmental uncertainty and business strategy which were shown to have an impact on all of the control types. Additionally, decentralisation, ownership dispersion and firm size are responsible for a change in three of four MCS types. Other interesting findings are that an increase in innovation capability is not associated with a reduction in results and action control intensity, and is positively related to the application of personnel and cultural control. Furthermore, important sources of finance, venture capital and public funding, are both shown to be positively associated with the application of action control; whereas, contrary to expectation, venture capital is found to be negatively correlated with personnel control. Overall, the results indicate that direct control is as important as indirect control given specific contingency factors. This study synthesises the fragmented literature of MCS contingency research in innovative settings by developing an original contingency model. The thesis adds value by inferring particular forms of management control which may be appropriate in innovative company settings. Thereby, the study contributes to both contingency research and to the knowledge and understanding of management control in innovative settings. It can assist managers by identifying MCS categories that are typically associated with particular influential factors. Further, the study is valuable from a methodological perspective by developing and testing novel constructs for three MCS categories. Beyond the relevance of the results to management control researchers, innovation company managers and policy makers, they also imply avenues for further related investigation.

Full textAbstract:
This dissertation provides fundamental conceptual building blocks for a new theory of IS implementation. The main argument presented is for a new perspective to supplement and complement the main existing perspectives on IS implementation: the technological determinist perspective, the managerial imperative perspective, and the socio-technical interactionist perspective. in this the research seeks to overcomes identified shortcomings of these existing approaches to understanding IS implementation. The research methodology emphasizes multidisciplinary theory-building, based on the resource-based approach to strategy, using autopoiesis as the key organizational epistemology. The research explores the concept of organizational climate dimensions as the shapers of organizational contexts, and relates these to information systems research in implementation. The new perspective developed emphasizes managerial action and organizational contexts as a mid-level approach, bridging the gap between top-down, rationalist methods and bottom-up, emergent approaches. Based on this conceptual framework, the context for IS corporate governance is operationalized and presented as a causal model with five independent variables - IS Intent, Discipline, Trust, Support and Structural IS-related factors and one independent variable. IS-Organizational Learning. Data collection is carried out in large Portuguese companies by means of a postal questionnaire. The empirical data is supplemented by five short case studies. The key conclusions of the thesis are: (1) The duality managerial action - organizational contexts opens up whole new possibilities for research and practice of IS implementation. (2) The use of the notion of organizational contexts dimensions as a research tool allows the analysis to go deeper than the vague generalization about organizations found in most current literature. (3) The use of quantitative methods to investigate IS-related organizational contexts is not suitable, except for descriptive purposes; semi-structured interviews and in-depth case studies are recommended. (4) Two specific dimensions of IS-related contexts are suggested as topics for further investigation: IS Intent and IS structural factors.

Full textAbstract:
Implementing effective leadership strategies in management of information systems (MIS) can positively influence overall organizational performance. This study was an exploration of the general problem of failure to lead effectively in the current knowledge-based economy and the resulting deleterious effects on organizational performance and threats to continuing organizational viability. The specific problem was the lack of understanding regarding the interaction of leadership processes with MIS functions and the impact on organizational success. Managers' and employees' lived experiences of leadership in small- to medium-sized enterprises were explored, as well as how those experiences influenced the organization's adaptive responses regarding technology and performance in the knowledge-based economy. The complexity theory of leadership was applied as the theoretical foundation for this study. A phenomenological methodology was used. Data were collected through semi-structured interviews and analyzed through open coding to identify emergent themes from the data. The themes were leaders motivate employees' positive work-related behaviors, effective communication skills ensure accessibility and efficiency of the organizational information system, and leadership practices influence business productivity. This study contributes to social change by providing insights for managers and employees regarding effective strategies for working as teams and networks via the use of nontraditional leadership theory, which promotes company sustainability by demonstrating the benefits of responding to the changing economy.

Full textAbstract:
With the rapid increase in information availability, it is nearly impossible to stay current with advances in knowledge. The overarching question that my dissertation seeks to address is how to design Web-based knowledge management systems (KMS) to alleviate this problem by providing search and analysis support for individuals to access and understand the accumulated knowledge in an effective and efficient way. Specifically, designing and implementing consistent representation of heterogeneous data, enabling efficient and user-friendly search support, and supporting advanced user-interactive analysis and visualization are important issues to address. Certain Information Systems and cognitive theories can be leveraged to guide the design and evaluation of these systems. In addition, the evaluation results can further validate and extend theory. This helps to bridge the design-science paradigm and the behavioral-science paradigm.The research studies in my dissertation involve the development of Web-based KMS based on different types of data sources. Such systems aim to support decision making and can be important for researchers, practitioners, business investors, and policy makers. Chapter 2 develops a Web-based KMS, Arizona Literature Mapper, which allows users to gain comprehensive understanding of bioterrorism research. The data source of Arizona Literature Mapper is scientific publications. The system integrates techniques for content analysis, network analysis, and information visualization. Two user studies were conducted to evaluate the performance of Arizona Literature Mapper. Guided by cognitive fit and cognitive load theories, Chapter 3 develops a Web-based KMS, Nano Mapper, to support users' search and analysis of nanotechnology developments. The data sources include patent documents from world leading patent offices and NSF grand documents. Controlled experiments were conducted to evaluate the functions of Nano Mapper. The Web-based KMS developed in Chapters 4 and 5 is the Dark Web Forum Portal (DWFP) which aims to manage user-generated multilingual social media content. In Chapter 4, theories of the mental workload, task-technology fit, and unified theory of acceptance and use of technology (UTAUT) are used to guide the design and development of the system, and a new theoretical model is proposed to extend theory. Chapter 5 conducts two evaluation studies to comprehensively evaluate the performance of the system. The first study compared its performance with the benchmark system based on efficiency, effectiveness, and all the dimensions in the D&M IS Success Model. The second study further tested and validated the D&M IS Success Model in social media context.Overall, these research studies in my dissertation contribute to the literature on system development, knowledge mapping, technology acceptance and adoption, and human cognition and decision making.

Full textAbstract:
The main aim of this thesis is an investigation into Destination Management Systems (DMS) website effectiveness and evaluation in the tourism domain from both academic and industry (destination management) perspectives. This thesis begins with a comprehensive review of the literature about theories, concepts and methods used for DMS website effectiveness evaluation. The future direction of DMS website evaluation in tourism and a conceptual framework that defines the contemporary theory versus practice of the DMS websites evaluation is elaborated. The research employed first three rounds of Delphi study to generate an up-to-date definition and aims of DMS. The Delphi study also generated an up-to-date comprehensive set of dimensions and criteria for evaluating the effectiveness of DMS websites. The research then employed structured interviews as well as online survey sent to forty-six official destination websites to review how industry is evaluating their DMS websites. What approaches they use in addition to the criteria and dimensions when evaluating the effectiveness of their DMS websites is explored. This thesis also reviews additional aspects related to the in destination evaluation. The findings of the Delphi study indicated that there is a rising emergence of social media as a new important component related to DMS. The findings also suggested additional aims to previously identified aims of the DMS. The new additional aims of DMS found in this research are: support sustainable destination management; empower and support tourism firms; enable collaboration at the destination; increase consumer satisfaction level and capture consumer data. Further findings also indicated compared with these established by previous researchers there are new additions to the evaluation dimensions of DMS websites proposed which are: sustainability, marketing, collaboration issues, and goals of the website. The findings of this thesis indicated that there is a congruence and consensus between academic experts and industry in terms of the most dimensions that are crucial for DMS websites evaluation. The findings, however, indicated that there is limited parallel between criteria identified with the Delphi study and those found and used by destination management practitioners. This thesis calls for additional research to develop a support system to ensure a focused involvement between academia and industry in the area of DMS website evaluation. This thesis contributes to knowledge by generating an up-to-date and comprehensive set of dimensions and criteria for evaluating the effectiveness of a DMS website. This thesis also contributes to knowledge through the identification of the current dimensions, criteria, and evaluation approaches used by industry practitioners. This research adopted a strategy in presenting the literature review that enhanced the understanding of the DMS websites and their comprehensive evaluation in tourism. This research is one of the first studies in the tourism field that reviews and sheds light on and compares and contracts contemporary thinking on both academia and industry evaluation of DMS websites.

Burgess, Scott S. "A Systems Theory Approach for Studying Safety Management Systems for Operations of Small Helicopter Organizations." Thesis, Northcentral University, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10169559.
Full textAbstract:
Implementation of safety management systems (SMS) in small helicopter entities is not widespread and the variation in different types of missions (segments) in the helicopter industry make this situation very complex. In 2005, industry, government and manufacturers identified as the International Helicopter Safety Team (IHST) set out to reduce the global helicopter accident rates, and SMS implementation was one strategy. What was missing was measuring the effectiveness of SMS as related to incident or accidents (IA), or the relationship of these on operational effectiveness (OE). Small helicopter entities are the most numerous organizations but experience the most IA in this high-risk sector of aviation, and the existence of SMS in these entities is not regulated. Implementing SMS could have a positive effect on OE and IA and this non-experimental study contained a systems theory framework using structural equation modeling (SEM) in a partially mediated model to determine the relationships between three variables. Further, these results support industry initiatives to target the small helicopter segment. This model could also be useful in promoting SMS implementation by justifying the positive effects of SMS integration, and to address the influence of SMS across the industry. Participants included crewmembers of small helicopter entities in the United States. A total of 205 participants were gathered to participate in the study. The findings of the study indicated that (a) safety management systems can predict incidents and accidents; (b) incidents and accidents mediate the relationship between SMS and OE; and (c) incidents and accidents predict operational effectiveness. Future researchers may expand the results of this study by performing aviation-safety-specific research and by identifying operational benefits of the systems approach.

Full textAbstract:
This thesis develops a conceptual framework for relating Social Capital theory to large IT outsourcing projects. It uses this to explore how social factors that arise in outsourcing situations can influence organisations’ competence in IT innovation. It finds that social capital principles provide a valuable alternative perspective to established practices in managing IT outsourcing. Social capital can be applied both in the analysis of IT outsourcing results and in planning outsourcing transitions that lead to improved longer term knowledge creation and innovation capability. Research was carried out in two large and established users of IT outsourcing, a UK government agency and a major bank. Based on this, two detailed case studies were prepared and an interpretive methodology used to understand how the respective outsourcing projects had developed. A conceptual model of the interacting organisational factors that lead to IT competence is derived from existing literature and tested against the case study data. This model sets out the new concept of an ‘outsourcing enclave’ as a unique structure in which knowledge resources of outsourcing client and vendor are combined, supported by social capital that is distinct from that in either feeding organisation. The thesis uses the model to observes how, in the cases studied, effective management of social capital in outsourcing enclaves has created situations conducive to knowledge creation and innovation and the barriers to this that were encountered. This reveals that social capital management in these organisations called for time after outsourcing transition during which social capital can stabilise in the enclave, for learning from the achievement of short term objectives and for application of relational governance alongside the outsourcing contract. The main contributions of the thesis are the conceptual framework of the outsourcing enclave and the use of this to apply social capital theory to specific situations of IT outsourcing. It also demonstrates how theorised dimensions of social capital can be used to interpret outcomes in real outsourcing situations. The cases provide further empirical support for social capital theory and their interpretation a basis for further research in the specific area of outsourcing and IT outsourcing in particular.

Full textAbstract:
The group decision making literature defines three methods of decision making used by and within groups: consensus, negotiation, and voting. Group support systems (GSS) research, with the creation of its enabling technologies, has focused on issues that support consensus-building and negotiation, thus relegating voting to the relatively limited role of prioritization. Surprisingly, the technology of aggregating opinions in GSS has received little research attention, and the procedures for it that have been implemented in even the most sophisticated groupware systems are relatively unsophisticated. Influence allocation processes (IAP) are voting and opinion aggregating methods that allow members to distribute some or all of their decision making influence to others in the group in order to exploit not only the group's knowledge of the alternatives, but its knowledge of itself. Only with the common use of GSS has their use become practical. Two families of influence allocation processes are reconsidered and expanded in this dissertation: SPAN, introduced by MacKinnon (1966a) and a technique based on a proposal by Morris DeGroot (1974) called Rational Consensus by Lehrer and Wagner (1981), who developed it and explicated it as a normative standard for combining opinion. This dissertation first considers the development and implementation of a set of IAP voting tools within GroupSystemsᵀᴹ. Second, a series of empirical studies is used to show how decision groups use voting tools for the selection of a correct solution. Third, simulation studies are used to develop guidelines for the allocation of influence in an alternative forced-choice problem. Finally, a case study of a real group using IAP for an authentic decisional problem is described. Influence allocation processes help reconcile differences in opinion, knowledge, and judgment. As such, they show much potential for improving the efficiency and effectiveness of group decision-making.

Full textAbstract:
Knowledge has become one of the most important assets for companies nowadays. Knowledge Management (KM) uses organizational knowledge as a resource to make companies more competitive. Knowledge Management Systems (KMS) are gaining popularity, however, the failure rate remains high, with many projects not achieving their goals or being shut down early. KMS are often underestimated and treated as normal systems. IS practices do not cover certain aspects specific to KMS, aspects that do not show in other IS (e.g. socio-cultural issues). There are many studies concerning the KMS failures but they just focus on the symptoms and do not provide a solution to the problem. The goal of this master’s dissertation is to generate a preventive tool that will help the KM field. With The experience gained by working in a real KMS project within a textile agency in Sweden and relevant literature, an Information Systems Design Theory (ISDT) for KMS was developed. As some authors suggest, KM needs an ISDT of it’s own. An ISDT will guide practitioners through the process by restricting practices and features of the system to a more effective set. It will also encourage the academia to work on this theory for its improvement, completion, and validation

Full textAbstract:
Systems thinking. Systems theory. The systems approach. All these concepts have in various guises been claimed as central to logistics management, since its dawning in the mid twentieth century. Such claims are the starting point of this dissertation, the purpose of which is to contribute to an increased understanding of systems thinking in logistics management research, both present and for future advances. The primary unit of analysis in this dissertation is thus logistics management research. The purpose is pursued through a strategy of triangulation of research approaches, via two research objectives: To describe the nature of systems thinking in logistics management research. To explore the merits for logistics management research of an interpretive approach to actors’ systems thinking. The term systems thinking in this dissertation denotes any somewhat ‘organised’ bodies of thought with aspirations to be ‘holistic’ in the sense of aiming for comprehensiveness. This part relates mostly to the systems part of the term. With regard to the other part, systems thinking is also regarded as a term that encompasses thinking about, and in terms of, systems; either that of researchers or that of actors in logistics practices. Systems thinking can sometimes be theorised on in such a way that it seems fair to label it as systems theory. Another term that is also frequently employed is systems approach. This denotes any approach to intervene in and/or conduct research on enterprises, with a holistic ambition. Such approaches can or cannot be informed by systems theory. By approach is meant the fundamental assumptions of the effort, such as ontological and epistemological positions, views on human nature, and methodologies. This dissertation employs an approach informed by a strand of systems theory labelled Critical Systems Thinking (CST). This builds on a pluralist strategy, which entails an awareness of the strengths and weaknesses of all types of systems approaches, and thus strives towards putting them to work under such circumstances in which they are best suited. The first objective is pursued by means of a combined inductive-deductive approach presented mainly through two peer-reviewed, published journal articles. The first is an extensive literature review of academic publications in logistics management; the second is a survey of logistics management academics. Results show that the systems thinking within the discipline most often is not informed by systems theory, and is oriented towards a narrow section of the available systems approaches. This is an approach that builds on an objective world-view (realist ontology), and which seeks knowledge in terms of different kinds of law-like regularities. There are variations to the kinds of knowledge that are sought, in the sense that some search for deeper, underlying generative mechanisms (structuralist epistemology), some seek causal relationships among observable phenomena (positivist epistemology). The common view on human nature is determinist, and methodologies are often quantitative. It is concluded that logistics management employs a functionalist systems approach, which implicitly assumes homogeneity in actors’ systems thinking in mutual contexts (i.e. shared logistics practices). The second objective is pursued by adopting an interpretive systems approach, thus embracing a nominalist ontology and interpretivist epistemology, in order to explore what benefits such a perspective can lend to logistics management. Informed by the pluralist commitment of CST, theoretical constructs and methods grounded in cognitive psychology are employed to study logistics management practitioners’ systems thinking through cognitive mapping. If this reveals heterogeneities in systems thinking among actors of a mutual context, in which a high degree of homogeneity can be expected, the rationale is that the dominant homogeneity assumption is insufficient. The study, presented through an unpublished working paper, concludes that actors’ systems thinking can differ in ways that render the assumptions of the functionalist systems approach inadequate. More thought, debate, and research on an interpretive systems approach within logistics management is called for. With constant expansions in the scope of ambition for logistics management in mind – towards larger enterprise systems in the spirit of supply chain management, towards more goals for enterprises than the traditional financial ones, and towards new application areas (e.g. healthcare) – it is recognised that more and more actors become stakeholders in the practices that logistics management research seeks to incorporate within its domain of normative ambitions. This leads to an expanding scope of voices that ought to be heard in order to legitimise efforts to improve logistics management practices. This in turn motivates that we should seek to accommodate not only interpretive systems approaches, but also emancipatory, in order to ensure normative prescriptions that are legitimate from the perspectives of as many stakeholders as possible, not only from the common a priori efficiency perspectives of functionalist logistics management research.

Joseph Tainter's theory of societal collapse is applied in an examination of the U.S. Air Force's aircraft acquisition system in order to gain insight into the enterprise's lagging performance. Theories of collapse at both the societal level and the organizational level are reviewed. Tainter's interrelationship between increasing system complexity and diminishing marginal returns is highlighted as especially relevant to the performance of the Air Force aircraft acquisition enterprise. Using Tainter's theory as a framework, evidence is gathered leading to the conclusions that the Air Force aircraft acquisition enterprise is highly complex and as a result is experiencing diminishing marginal returns. Tainter's framework is then also used to explain why past attempts to reform the enterprise have fallen short of their goals. Previous reform efforts, in the form of reorganizations and senior leader initiatives, have been ineffectual beyond the short term because they fail to reduce the underlying level of complexity within the enterprise. The use of workarounds by stakeholders within the enterprise are shown to be efforts to increase marginal returns and avoid overcomplexity. The primary implication of viewing the Air Force aircraft acquisition enterprise through the lens of Tainter's theory of collapse is that in order to be effective, any effort undertaken to improve the performance of the enterprise must reduce the overall level of complexity within the system. Additional insights include the use of current workarounds as leading indicators of complexity or overly burdensome processes. Lastly, senior acquisition leaders should be prepared should a collapse of the enterprise occur. A vision of a much less complex enterprise should be advocated.

If we are to manage cyber security risks more effectively in today's complex and dynamic Web 2.0 environment, then a new way of thinking is needed to complement traditional approaches. According to Symantec's 2014 Internet Security Threat Report, in 2012 more than ten million identities that included real names, dates of birth, and social security were exposed by a single breach. In 2013 there were eight breaches that each exposed over ten million identities. These breaches were recorded despite the fact that significant resources are expended, on managing cyber security risks each year by businesses and governments. The objective of this thesis was twofold. The first objective was to understand why traditional approaches for managing cyber security risks were not yielding desired results. Second, propose a new method for managing cyber security risks more effectively. The thesis investigated widely used approaches and standards, and puts forward a method based on the premise that traditional technology centric approaches have become ineffective on their own. This lack of efficacy can be attributed primarily to the fact that, Web 2.0 is a dynamic and a complex socio-technical system that is continuously evolving. This thesis proposes a new method for managing cyber security risks based on a model for accident or incident analysis, used in Systems Safety field. The model is called System-Theoretic Accident Model and Processes (STAMP). It is rooted in Systems Thinking and Systems Theory. Based on a case study specifically written for this thesis, the largest cyber-attack reported in 2007 on a major US based retailer, is analyzed using the STAMP model. The STAMP based analysis revealed insights both at systemic and detailed level, which otherwise would not be available, if traditional approaches were used for analysis. Further, STAMP generated specific recommendations for managing cyber security risks more effectively.

Full textAbstract:
The purpose of this research is to develop a comprehensive, IS assessment framework using existing IS assessment theory as a base and incorporating suggestions from other disciplines. To validate the framework and to begin the investigation of current IS assessment practice, a survey instrument was developed. A small group of subject matter experts evaluated and improved the instrument. The instrument was further evaluated using a small sample of IS representatives. Results of this research include a reexamination of the IS function measurement problem using new frameworks of analyses yielding (a) guidance for the IS manager or executive on which IS measures might best fit their organization, (b) a further verification of the important measures most widely used by IS executives, (c) a comprehensive, theoretically-derived, IS assessment framework, and by (d) the enhancement of IS assessment theory by incorporating ideas from actual practice. The body of knowledge gains a comprehensive, IS assessment framework that can be further tested for usefulness and applicability. Future research is recommended to substantiate and improve on these findings. Chapter 2 is a complete survey of prior research, subdivided by relevant literature divisions, such as organizational effectiveness, quality management, and IS assessment. Chapter 3 includes development of and support for the research questions, IS assessment framework, and the research model. Chapter 4 describes how the research was conducted. It includes a brief justification for the research approach, a description of how the framework was evaluated, a description of how the survey instrument was developed and evaluated, a description of the participants and how they were selected, a synopsis of the data collection procedures, a brief description of follow-up procedures, and a summary.

Full textAbstract:
Despite the existence of extensive literature regarding risk management, there still seems to be lack of knowledge in identification of Critical Success Factors (CSFs) in this area. In this research Grounded Theory is implemented to identify CSFs in Risk Management Systems (RMS). Factor analysis and one-sample t-test are then used to refine and rank the CSFs based on the results of a survey which has been performed among Risk Management practitioners in various types of Swedish corporations. CSFs are defined from three different perspectives: (a) the factors that have influence on the inclination and readiness of corporation for implementing RMS. (b) the factors that are important during the design and implementation of RMS in corporation and can significantly affect the success of RMS design and implementation and (c) the factors that are crucially important to successfully run, maintain and administrate RMS after the closure of the project of RMS design and Implementation.
This systematic approach towards understanding the taxonomy of the success dimension in RMS is important for re-enforcing effective risk management practices.

Full textAbstract:
The core essence of a marketing transaction is the exchange of value between two parties. Quite often, the exchange of value describes a customer purchasing a product from a company. When purchasing products, the exchange of value can often fail due to product defects or customer dissatisfaction. When the marketing exchange fails, customers often desire an avenue for recourse to right the exchange imbalance. Accepting and quickly processing product returns represents a strategic tool companies can leverage to maintain healthy relationships with customers, despite an exchange failure. Effectively managing product returns also benefits companies financially, by reducing inventory levels, costs, and the risk of product obsolescence. Despite providing both relationship management and financial benefits, numerous companies struggle to manage product returns effectively. In a time when companies are facing a growing number of product returns due to omni-channel retailing and online shopping, implementing an effective system to manage product returns has become a vital strategic tool necessary to maintain competitiveness.
First, the current research answers the question of why do companies struggle with product returns? by identifying the important components of an effective product returns system. Informed by complex adaptive systems theory and based on a qualitative, grounded theory analysis, the current research finds that the hidden complex nature of managing product returns prevents numerous companies from implementing an effective system to mange returns. Managing product returns requires five important components (firm capabilities, employees, the returns management information system, organizational climate, and the customer service boundary), which interact with each other multiple times to process a product return. After identifying the important components and interactions within a product returns system, Essay I integrates the information together to form a substantive theory of the complexity of product returns management. The substantive theory implies that companies looking to improve their management of product returns need to understand and invest in multiple components within the product returns system.
Second, the current research answers the question of how do the employees, returns management information system, and climate for creativity components of a product returns system relate to a firm’s flexibility, adaptability, and performance? To answer this research question, this dissertation empirically evaluates the role these three components play in shaping a firm’s flexibility, adaptability, subjective performance and relationship quality by analyzing data collected through an online survey with 102 US managers with experience in product returns. The empirical analysis indicates that employee decision-making resources show a statistically significant negative relationship with firm adaptability, while the firm’s climate for creativity and flexibility show a statistically significant positive relationship with firm adaptability. Firm adaptability shows statistically significant positive relationships with subjective performance and relationship quality. Firm adaptability acts as a partial or full mediator in all of these relationships.
The combined findings of Essay I and Essay II point to the importance of product returns as a strategic relationship management tool. Firms that can effectively manage product returns give employees more flexibility to respond to problems, are better able to make structural changes, have higher subjective performance ratings, and better quality relationships with customers.

University of Technology, Sydney. School of Management, Faculty of Business.This study investigated how selected Australian universities evaluated and adopted various learning management systems in their teaching and learning programs, given claims of uncritical evaluation, problems and cautions in the Australian (1998: 13; Brabazon, 2002; Yetton, Forster, Hewson, Hughes, Johnston, Nightingale, Page-Hanify, Vitale and Wills, 1997) and North American (Berg, 2002; Noble, 1998b) higher education literatures. Ironically, universities charge large amounts of money teaching their students to develop competence in critical analysis, yet some studies have claimed that they were deficient in critically analysing their own decisions (Brabazon, 2002; Yetton et al., 1997). This important question has received little attention in the higher education literature, despite the high visibility and costs of these decisions. Although limited theoretical explanations have been proposed by various researchers, such as Yetton et al. (1997) and Brabazon (2002), these matters have not been the subject of published empirical research to date. A grounded theory methodological framework, validated by the insights of institutional theory, was employed throughout to promote broader sociological explanations than other studies constrained by functionalist theoretical frameworks (Yetton et al., 1997). Qualitative case studies utilising semi-structured interviews and document analysis were conducted at three Australian universities. The findings of this analysis were written up in three case study narratives and an analytic cross-case analysis. Semi-structured interviews and document analysis at the field level were undertaken as an additional source of data to verify emergent grounded theory. A grounded theory of uncritical decision making (Figure 57) was ultimately developed in response to this study’s research problem. The core category around which this model was developed (‘falling behind’) appeared in all three cases, in interviews with experts from the Australian higher education sector, and was also found in both the Australian and overseas higher education literatures. This grounded theory also represents a minor contribution to the institutional theory literature as a new institutional change process model which links the activities of key individuals with broader field developments, and integrates the constructive and reproductive assumptions of old and new institutional theory.

Full textAbstract:
Though knowledge has become an increasingly important resource for modern businesses, it was not until the mid-1990's that the 'knowledge management' research stream emerged in the business and information systems literature. Initial research on how to manage knowledge came from an objectivist epistemology of knowledge that viewed it as something that was capable of captured, stored and transferred via information to increase organisational efficiency. This study is grounded in a more recent and alternative perspective that takes a practice based epistemology seeing knowledge as embedded in and inseparable from practice. The practices of interest relate to how knowledge work is performed in environments where there is heavy reliance on information systems. Using an interpretive case study this research analyses the practices of a product support centre of a US multinational. Data was collected through semi-structured interviews and internal documentation, including access to the firms „knowledge management‟ repository. Two central practices were examined: how product support engineers made sense of problems to develop fix procedures and how these were subsequently documented. Even within a work environment where client fixes were verifiable, suggesting an objectivist epistemology, this research found that the practice based perspective could be used to provide a different perspective and develop alternative and useful insights. The study contributes to the practice based perspective on knowledge management by providing an analysis of context specific knowledge work practices by analysing how even in procedural repetitive work agency can be exhibited as actors enact practices. It also helps develop the application of Structuration Theory by aiding an understanding of how meanings, norms and resources are developed, drawn upon, conflict, and are changed as everyday work is accomplished. The study is of relevance by providing an understanding of informal knowledge work practices rather than their formal description.

Full textAbstract:
Thesis (PhD)--Stellenbosch University, 2005.ENGLISH ABSTRACT: To maximise the throughput of a production system the capacity constrained resource needs to be protected from variation and uncertainty. In the Theory of Constraints philosophy such protection is provided by means of time buffers and protective capacity. Time buffers are protective time that is allowed in the production schedule to buffer against disruptions, whereas protective capacity is defined as a given amount of extra capacity at non-constraints above the system constraint's capacity. In this research an analytical procedure was developed to more accurately determine the required time buffer lengths. This procedure uses an open queuing network modelling approach where workstations are modelled as GIIG/m queues. A simulation experiment was performed to evaluate the time buffer estimation procedure on the operations of an actual fifteen station flow shop. The results from the study suggest that the analytical procedure is sufficiently accurate to provide an initial quick estimate of the needed time buffer lengths at the design stage of the line. This dissertation also investigated the effect of protective capacity levels at a secondary constraint resource as well as at the other non-constraint resources on the mean flow time, the bottleneck probability of the primary constraint resource, as well as the output of flow production systems using simulation models and ANOV A. Two different types of flow production systems were investigated: (1) a flow shop with a fixed number of stations and unlimited queue or buffer space between stations, and (2) an assembly line where a total work content is distributed among stations in a certain fashion and the number of stations are not fixed. The experimental studies show that flow shop performance in the form of flow time and line output is not that much influenced by low protective capacity levels at the secondary constraint resource. Low protective capacity levels at a single station however can significantly reduce the bottleneck probability for the primary constraint resource when it is located before and relatively close or near to the primary constraint in the process flow, or after but relatively far from the primary constraint. An after-far secondary constraint location also causes slightly longer job flow times, and should therefore be avoided if possible. The research further shows that quite high protective capacity levels at the nonconstraint resources are needed to ensure a more stable and therefore manageable primary constraint. However low average levels of protective capacity at non-constraint resources are sufficient to ensure that the maximum designed output level as determined by the utilisation of the primary constraint resource is obtained. The results for the assembly line experiment showed that an unbalanced line configuration where less work is assigned to the non-constraint stations than to the primary constraint station (but nonconstraint stations have an equal work content) can lead to significant reductions in the mean flow time while maintaining the same line output, without resulting in too many additional stations. Low protective capacity levels in the range of 2% to 5% are sufficient to cause substantial improvements in flow time without resulting in too many additional stations in the line.
AFRIKAANSE OPSOMMING: Om die finale uitset van 'n produksiestelsel te maksimeer is dit noodsaaklik dat die bottelnek beskerm word teen fluktuasies en onderbrekings. In die "Theory of Constraints" filosofie word van twee soorte beskermingsmeganismes gebruik gemaak: tydbuffers en beskermende kapasiteit. Tydbuffers is beskermende tyd wat in die produksieskedule gevoeg word om sodoende die bottelnek teen onderbrekings te beskerm, terwyl beskermende kapasiteit ekstra produksiekapasiteit relatief tot die bottelnek se kapasiteit is wat by nie-bottelnekke gevoeg word. In hierdie navorsing IS 'n analitiese prosedure ontwikkel om meer akkurate berekenings van tydbuffergroottes te verkry in produksiestelsels wat volgens 'n "Theory of Constraints" filosofie bestuur word. Die prosedure maak gebruik van oop toustaan netwerk modellering waar werkstasies gemodelleer word as GIIG/m toue. Die analitiese prosedure is ge-evalueer met 'n simulasie eksperiment op 'n werklike vyftien stasie vloeiwinkel. Die resultate dui aan dat die analitiese prosedure akkuraat genoeg is om vinnig aanvanklike beramings vir die benodigde tydbuffergroottes tydens die ontwerpsfase van die produksiestelsel te verskaf. Verder is ook ondersoek ingestel na die effek van beskermende kapasiteitsvlakke by die sekondêre bottelnek asook die ander nie-bottelnekke op die gemiddelde deurvloeityd, die totale uitset, asook die bottelnek waarskynlikheid vir die primêre bottelnek in vloei produksiestelsels deur gebruik te maak van simulasie modelle en ANOVA. Twee verskillende tipes vloei produksiestelsels is ondersoek: (1) 'n vloeiwinkel met 'n vaste aantal stasies en 'n onbeperkte buffer spasie tussen stasies, en (2) 'n monteerlyn waar 'n totale werksinhoud op 'n bepaalde wyse onder stasies verdeel moet word en die aantal stasies nie vas is nie. Die eksperimentele studies dui aan dat die deurvloeitye en totale uitset van 'n vloeiwinkel me noemenswaardig beïnvloed word deur lae beskermende kapasiteitsvlakke by die sekondêre bottelnek nie. Hierdie maatstawwe word meer beïnvloed word deur die gemiddelde beskermende kapasiteitsvlakke by al die nie-bottelnekke. Lae beskermende kapasiteit by 'n enkele werkstasie kan egter die bottelnek waarskynlikheid vir die primêre bottelnek aansienlik verlaag indien dit voor en relatief na aan die primêre bottelnek in die prosesvloei geleë is, of na, maar relatief ver, vanaf die primêre bottelnek. 'n Sekondêre bottelnek ligging na maar relatief ver vanaf die primêre bottelnek in die prosesvloei veroorsaak ook langer deurvloeitye, en moet dus vermy word. Verder dui die navorsing aan dat redelike hoë gemiddelde beskermende kapasiteit by nie-bottelnekke benodig word om 'n meer stabiele primêre bottelnek te verseker. In vloeiwinkels met lae vlakke van variasie en onderbrekings is egter lae gemiddelde vlakke van beskermende kapasiteit by nie-bottelnekke voldoende om te verseker dat die maksimum ontwerpte uitset soos bepaal deur die benutting van die primêre bottelnek behaal word. Die resultate vir die monteerlyn eksperiment dui aan dat 'n ongebalanseerde lynkonfigurasie waar minder werk aan die nie-bottelnek stasies as aan die primêre bottelnek stasie toegeken word (maar niebottelnek stasies het 'n gelyke werksinhoud), aansienlike verlagings in deurvloeityd teweeg kan bring terwyl dieselfde lyn uitset behou word. Dit is moontlik sonder te veel addisionele stasies in die lyn. Die eksperimentele resultate dui aan dat lae beskermende kapasiteitsvlakke van tussen 2% tot 5% voldoende is om beduidende verlagings in deurvloeityd teweeg te bring sonder te veel addisionele stasies.

The use of Web-Based-Collaboration-Systems (WBCS) continues to grow as part
of information technology development in the Architecture-Engineering-Construction
(AEC) industry. WBCS provide different media channels to support collaboration across
geographical distributed teams. However, many companies are still hesitant to integrate
WBCS.
This research provides an understanding of how WBCS are used in practice.
Most distinctively, it obtained practice data from several major US architecture firms
and examined about 30,000 transactions produced during actual design and planning
projects as practicing architects, engineers and consultants used WBCS. The study investigated
what information was used and exchanged among participants during the different
design stages. This was related to the different media channels of WBCS.
The raw project data has been coded and transformed into secondary data
through computer-supported content analysis. Based upon categories from previous literature,
such as communication, coordination and design theories, the data has been analyzed
for sender, receiver, channel and content of information transmitted. The content has been characterized into work tasks, information handling behavior and design activities.
Additional interviews with industry professionals produced information that had
not been documented through WBCS and that corroborated the analytical findings. The
combination of theory, quantitative, and qualitative analysis has been synthesized into a
portrait of WBCS usage that was validated through triangulation.
The analysis of digital records of design communication from practice through
content analysis is a new research methodology in AEC. The evidence supporting design
methods theory shows the changes in tasks and information handling in regards to the
project phases. It indicates that the most frequent loops of design activity are Evaluation-
Analysis-Synthesis and Evaluation-Synthesis-Evaluation. It documents the actual usage
of WBCS based on descriptive statistics and Markov models. WBCS was used primarily
as a document repository and calendaring tool. The remote team members used it more
frequently than centrally located participants. The study shows the limitations of WBCS:
none of the verbal communication was captured. More significant, the entire email exchange
took place outside the WBCS. WBCS was used very extensively, if the implementation
of the system supported the organizational structure and vice versa.

This dissertation presents a theoretical model of information systems (IS) project management that aims to improve the rate of project success, estimated at time of writing to be less than 50% despite over thirty years of experience. The inquiry into IS managementand the development of the CED Model of IS Project Management presented in this dissertation were informed by critical social theory and pragmatics. IS projects are conceptualised as a collaborative undertaking by everyone affected by the project : the constituents. The model identifies the central role of constituents' expectations and their critical examination of the intended, desired and feared outcomes. By being based in the political, economic, technical and social dimensions of IS projects, this dissertation makes a theoretical contribution to the IS discipline. Furthermore, by establishing a set of prescriptions for how a project should be conducted by identifying who should take part (the constituents), how they should interact(engaging in the project discourse) and how the processes should be managed(driven by the constituents' expectations), the model provides guidance for IS practitioners to increase the likelihood of successfully implementing the project. From a research perspective, this dissertation presents an example of empirically grounded IS research, informed by critical-pragmatic theoretic concerns, that is highly relevant for IS practice.Doctor of Philosophy (PhD)

Full textAbstract:
Strategic decision-making is a fundamental process in business management as strategic decisions affect the long-term health of the organisation. However, a constantly and unpredictably changing business environment, becoming progressively more complex as time passes makes strategy formulation increasingly difficult. Shock events such as terrorist attacks, rapidly spreading communicable diseases, and unexpected business failures of large and well-established companies greatly affect organisations by making it difficult to effectively plan for the future. This thesis contributes to the strategic decision-making literature by investigating the role of shock events in a complex system, namely strategic decision-making. Using chaos/complexity theory as an intellectual platform this thesis argues that strategic decision-making is a complex, open, dynamic and non-linear system and that shock events can represent an opportunity in strategic decision-making. A number of contemporary writers are calling for more integrated models. In response this research proposes a generic and integrative framework that highlights the complexity of strategic decision-making and its processes. The research is qualitative and a single-case study approach was chosen, examining the decision-making processes in a large Australian regional airport. Data collection was triangulated, consisting mainly of in-depth interviews with executives but also included questionnaires, and quantitative and qualitative archival data. It was found that shock events influenced strategic decision-making by causing evolutionary changes in the strategic decision-making processes. In addition it was found that shock events impacted on internal drivers such as cognition and organisational culture. The shock event was perceived as an opportunity, which resulted in changing decision-making processes a change in business strategy. It was concluded that environmental perception, intuition and an opportunity-seeking culture can play an important part in strategic decision-making following a shock event.

Autonomic computing aims at making computing systems self-managing by using autonomic managers in order to reduce obstacles caused by management complexity. This thesis presents results of research on self-management for large-scale distributed systems. This research was motivated by the increasing complexity of computing systems and their management. In the first part, we present our platform, called Niche, for programming self-managing component-based distributed applications. In our work on Niche, we have faced and addressed the following four challenges in achieving self-management in a dynamic environment characterized by volatile resources and high churn: resource discovery, robust and efficient sensing and actuation, management bottleneck, and scale. We present results of our research on addressing the above challenges. Niche implements the autonomic computing architecture, proposed by IBM, in a fully decentralized way. Niche supports a network-transparent view of the system architecture simplifying the design of distributed self-management. Niche provides a concise and expressive API for self-management. The implementation of the platform relies on the scalability and robustness of structured overlay networks. We proceed by presenting a methodology for designing the management part of a distributed self-managing application. We define design steps that include partitioning of management functions and orchestration of multiple autonomic managers. In the second part, we discuss robustness of management and data consistency, which are necessary in a distributed system. Dealing with the effect of churn on management increases the complexity of the management logic and thus makes its development time consuming and error prone. We propose the abstraction of Robust Management Elements, which are able to heal themselves under continuous churn. Our approach is based on replicating a management element using finite state machine replication with a reconfigurable replica set. Our algorithm automates the reconfiguration (migration) of the replica set in order to tolerate continuous churn. For data consistency, we propose a majority-based distributed key-value store supporting multiple consistency levels that is based on a peer-to-peer network. The store enables the tradeoff between high availability and data consistency. Using majority allows avoiding potential drawbacks of a master-based consistency control, namely, a single-point of failure and a potential performance bottleneck. In the third part, we investigate self-management for Cloud-based storage systems with the focus on elasticity control using elements of control theory and machine learning. We have conducted research on a number of different designs of an elasticity controller, including a State-Space feedback controller and a controller that combines feedback and feedforward control. We describe our experience in designing an elasticity controller for a Cloud-based key-value store using state-space model that enables to trade-off performance for cost. We describe the steps in designing an elasticity controller. We continue by presenting the design and evaluation of ElastMan, an elasticity controller for Cloud-based elastic key-value stores that combines feedforward and feedback control.QC 20120831
