For many organisations Information Technology (IT) enabled business initiatives and IT infrastructure constitute major investments. If these investments are not managed properly or the technological initiatives are not integrated correctly within the business, the organisation’s competitive position is impaired. Currently, both management and IT professionals are concerned with design, implementation, and assessment of IT governance strategies to ensure that technology truly serves the needs of the business. These strategies aim to align IT applications with the objectives of the business. The question addressed by this research is: How does a complex organisation devise, implement, and assess its IT governance arrangements? Devising IT governance arrangements is challenging because the success of IT strategies and procedures is contingent upon a variety of internal and external factors, such as workgroup interdependency and competitive strategy. Implementing an IT governance framework can be a complex endeavour because organisations must integrate the unique expertise of diverse stakeholders and service providers. This research explores the factors influencing the IT governance structures, processes, and outcome metrics. Using data from an in-depth case study conducted in a complex energy organisation, this research provides empirical evidence that increases our understanding of IT governance arrangements. Interview responses indicated that effective IT governance performance outcomes are characterised by a shared understanding of business and IT objectives; active involvement of IT steering committees; a balance of business and IT representatives in IT decision making; and comprehensive and wellcommunicated IT strategies and policies. IT governance plays a key role in fostering project success and delivering value. Effective IT project governance outcomes are characterised by the existence of executive leaders as project champions of IT, the use of appropriate measurement techniques during a priori and interim evaluations of IT projects, and extensive post implementation evaluation.

There is an increasing needto design and implement technological solutions to span scientific advances, facilitate people’s life and increase the efficiency of daily tasks. This bringsinto the picture professionals with sufficient technical skills to bring to life these technological solutions. Considering the outreach and size of said solutions, technical knowledge is not enough to succeed, but softskills such as communication and teamwork. Engineering and technology professionals need to function effectively in teams to accomplish a common goal. Therefore, this study characterizes the strategies that teams use in order to accomplish their goals through successful team interactions.In addition, this study explores how these strategies vary during asemester-longproject and how these variations mayaffectteam interactions and different performance indicators

Efficient organization requires rigorous and systematic information management, which encompasses information processing and decision making. Within the efforts in management science and informatics invested towards advancing the knowledge on, and providing assistance to decision making, this thesis focuses on the conceptualizations and techniques intended to facilitate the identification, evaluation, and selection of decisions during the earliest stages of information systems engineering, whereby the systems of interest are deployed to partly or fully automate various organizational processes, including information processing ones. The overall motivating problem that drove to, and that unites the various contributions presented in this thesis is how to better inform decision making and guide it towards decisions that will increase the quality (as evaluated both by the engineer and the stakeholders) of the information system being engineered. Topics in two key related areas are therefore addressed. First, boundedly rational individuals cannot take engineering decisions by accounting for all information that may be, or actually is available to them. As their information processing abilities are limited and their perception biased, it is necessary to filter the available information to a manageable level, and to bring it to a format that facilitates the rigorous reasoning invested in decision making. Second, it is necessary to provide guidance on how to use the given information in decision making. The first part of this thesis therefore focuses on conceptualizations that facilitate the identification of relevant information and its organization for subsequent analysis, all in the aim of achieving high quality of the system being engineered. In particular, Part I discusses, shows deficiencies, and accordingly revises the conceptual foundations of requirements engineering, a field of information systems engineering that focuses on the identification and analysis of requirements communicated by the stakeholders to the engineer of the system. The novelty of the suggested revision lies primarily in (i) the separation between functional and nonfunctional (i.e., quality) requirements grounded in a foundational ontology, (ii) the introduction of stakeholders' communicated attitudes as important sources of information for the evaluation of alternative requirements engineering decisions, (iii) the reformulation of the so-called ``requirements problem' -- which precisely defines when the requirements engineering effort is successfully completed -- to account for attitudes and nonfunctional requirements, and (iv) the recognition of the importance of defeasible reasoning in the search for a solution to the requirements problem. Acknowledging the importance of defeasible reasoning leads -- in Part II -- to the study of how defeasible reasoning can be incorporated into established decision making processes involved in the identification and analysis of requirements. Novelty in Part II lies mainly in (i) the use of argumentation and justification processes in the modeling and analysis of requirements, (ii) the combined use of design rationale approaches with argumentation and justification, (iii) the recognition that the clarity of arguments is variable (due to ambiguity, vagueness, synonymy, and overgenerality of information going into premises and conclusions in arguments), (iv) the definition of a number of techniques for the detection of unclear information and its clarification, and (v) the use of ``clarity' as a criterion for the discrimination among arguments. Part III shows how the conceptualizations and techniques introduced in Parts I and II are applied within and are relevant to the engineering of information systems, including those that rely on heterogenous and distributed components, as in service-oriented and agent-oriented computing.

This research examines the application of the ISO 9000 model for quality management in healthcare. Exploratory case study is made of three healthcare provider organisations: community health service; independent practitioner association; Maori health network. Three research models are developed to examine identified gaps and areas of interest in healthcare quality management literature. The first model relates to differences between generic standards and specification standards. The second model relates to the fit of healthcare service delivery systems and ISO 9000. The third model relates to exploration of the linkages and co-ordination of an integrated care delivery network. One proposition and two hypotheses are developed in relation to the models, and are closely associated with gaps in healthcare service quality knowledge. Strong support is found for the first hypothesis though not the second hypothesis, and there are also some unexpected results. There is strong support that the process of implementing the ISO 9000 model will enhance healthcare management performance, even though the outcomes are unpredictable. There are indications supporting the notion that implementation of the ISO 9000 model will increase effective linkages and co-ordination within integrated care delivery networks. The body of evidence accumulated during the study did not, however, permit a valid conclusion regarding the hypothesis. The findings of the study can be extended to other healthcare service areas and through interpretation and extrapolation they add value to healthcare service quality research in general. In particular, the findings of the three case studies in this research suggest that future models for healthcare service quality should include a comprehensive generic model for quality management of individual and integrated healthcare service organisations.

As organisations strive toward this end, researchers are attempting to better understand the alignment phenomenon. Empirical research into business-IT alignment is dominated by studies examining the relationship between business strategy, information technology and performance. Investigations into the factors enabling or inhibiting alignment are emerging. This research has traditionally taken a behavioural perspective. There is evidence of little research that examines the issue through a cognitive lens. This thesis builds on and extends the study of business-IT alignment by investigating the cognition of the key stakeholders of the alignment process - business and IS executives. Drawing on Personal Construct Theory (Kelly, 1955), this study uses a cognitive mapping methodology known as the repertory grid technique to investigate two questions: i) is there a positive relationship between business-IT alignment and shared understanding between business and IS executives?; and ii) are there differences in the cognitive maps of business and IS executives in companies that report high business-IT alignment and those that report low business-IT alignment? Shared understanding is defined as cognition that is held in common between and that which is distributed amongst business and IS executives. It is portrayed in the form of a cognitive map for each company. The study proposes that business-IT alignment is directly related to the shared understanding between business and IS executives and that the cognitive maps of these executive groups are less diverse in companies that report a high level of alignment. Eighty business and IS executives from six companies were interviewed. Cognitive maps were elicited from the research participants from which diversity between cognitive maps of business and IS executives are measured. A collective cognitive map was produced to illustrate the quality of the shared understanding in each company. The state of business-IT alignment in each company was also measured. The results of the study suggest that there is a strong positive link between business-IT alignment and shared understanding between business and IS executives. As expected, companies with a high-level of business-IT alignment demonstrate high quality shared understanding between its business and IS executives as measured and portrayed by their collective cognitive maps. The investigation further finds significant diversity in the structure and content of the cognitive maps of these executive groups in companies reporting a low-level of alignment. This study concludes that shared understanding, between business and IS executives, is important to business-IT alignment. Reconciling the diversity in the cognitive maps of business and IS executives is a step toward achieving and sustaining alignment. Practical approaches to developing shared understanding are proposed. A methodology to aid organisations in assessing shared understanding between their business and IS executives is also outlined. Finally research on business-IT alignment continues to be a fruitful and important field of IS research. This study suggests that the most interesting issues are at the interface between cognition and behaviour. The process of business-IT alignment in organisations is characterised by the individuality and commonality in the cognition of key stakeholders, its influence on the behaviour of these members and hence the organisational action taken.

Although there is a high risk of failure in the implementation of ICT projects (which appears to extend to health ICT projects), we continue to implement health information systems in order to deliver quality, cost-effective healthcare. The purpose of the research was to participate in and study the change management as a critical success factor in health ICT projects, and to examine people’s responses to change so as to develop understanding and theory that could be used in future change management programmes. The research was conducted within the context of a large infrastructure project that resulted from the emergence of a shared services organisation (from two participating District Health Boards in Auckland, New Zealand). Action research (AR) formed the basis of the methodology used, and provided the foundation for a change management programme: the AR intervention. Grounded theory (GT) was used for some of the data analysis, the generation of themes by means of constant comparison and the deeper examination of the change process using theoretical sampling. AR and GT together supported the development of theory regarding the change process associated with health ICT projects. Health ICT projects were revealed in the findings as exhibiting the properties of complex adaptive systems. This complexity highlighted the art of change management as a critical success factor for such projects. The fabric of change emerged as a composite of processes linked to project processes and organisational processes. The turning point in the change process from the before state to the after state is marked by a capability crisis which requires effective patterns of leadership, sensitive targeting of communication, effective learning, and management of increased workload and diminishing resources during the course of health ICT projects. A well managed capability crisis period as a component of change management can substantially contribute to health ICT project success.
