Abstract [en]

Most large enterprises are facing numerous challenges concerning their information systems, IS, and information and communication technology, ICT. Today, many enterprises employ a considerable number of applications that often have redundant functionality. There is also a large diversification in the ICT products and technologies employed. Further, integration costs are a major issue in almost all acquisition projects and many enterprises experience a lack of data quality and information security. The list of IS/ICT management challenges can be made much longer. At most enterprises, IS/ICT decisions are made by autonomous business units. In order to change the situation described above and build a more cost-effective IS/ICT environment, all business units need to make consistent IS/ICT decisions. Distributed and consistent decisions can only be made if the decision maker knows which decisions to make and why he/she needs to make them. The latter can be described by the target architecture for the whole enterprise IS/ICT, the information needed to conduct the business and its relationship to the business processes and business organization together with the benefits that the target architecture provides to the business. Which decisions to make are formulated into architectural principles, i.e. rules that express how your enterprise needs to design and deploy IS/ICT.

The present thesis is a composite thesis including eight papers. The first four papers describe the reference model for IS/ICT management responsibilities that is one of the outcomes of the present research. Two different surveys have been performed in order to find out what the major IS/ICT management challenges are. The first survey was answered by 62 Swedish Chief Information Officers, CIOs, from large private enterprises as well as municipalities. The second survey was answered by twelve CIO’s from the European electric power industry. In the fifth paper, one of the IS/ICT management responsibilities, i.e. data quality, is used to illustrate how the IS/ICT manager’s responsibilities can be decomposed into measurable units. Over 70 respondents were used in order to perform an enterprise- wide measurement of the data quality at a Swedish insurance company. The last three papers are devoted to architectural principles. Architectural principles are introduced and guidelines on how to define and manage them are proposed in the sixth paper. The guidelines have been used in a review of Vattenfall’s architectural principles. In the last two papers, architectural principles and the reference model are combined in a methodology for assessing the enterprise architecture. The methodology has been used in two different case studies, one at Vattenfall and one at Scania. In both case studies multiple information systems were assessed from many different viewpoints resulting in that many respondents were interviewed.

Abstract [en]

The challenge of IT management is today considerable. In industry, the organizational role of the Chief Information Officer (CIO) has been promoted as the owner of these challenges. In spite of a general acceptance of the problems associated with the responsibilities of the CIO, very little academic research has been conducted on the issues and constraints of this role. In order to address these shortcomings, this article presents the results of a survey in which Swedish CIOs have prioritized their most important concerns. In academia, a response to the IT system management challenges has presented itself in the discipline of Enterprise Architecture. The article argues that the CIO role is the primary stakeholder of Enterprise Architecture, so his/her need for decision support should guide Enterprise Architecture research and framework development. Therefore, the article presents a brief review over how well two existing Enterprise Architecture frameworks address the surveyed concerns of the CIO. Results from the survey indicate that the three highest prioritized concerns of CIOs are to decrease the cost related to the business organization, to improve the quality of the interplay between the IT organization and the business organization and to provide new computer-aided support to the business organization. The comparison between the CIOs' prioritization and the foci of the frameworks shows some discrepancies. The largest disharmony lies in the lack of decision support for issues related to the IT organization. Furthermore, support for explicitly estimating and managing costs is lacking within the frameworks.

Abstract [en]

The electric power industry heavily depends on IT. Earlier, business operations of most large companies were supported by a number of isolated software systems performing diverse specific tasks, from real-time process control to administrative functions. Today many companies possess a highly complex enterprise-wide IT system; in large organizations several hundreds of interconnected systems may be employed. The industry is challenged by two major changes; the integration of administrative systems and operation support systems and the deregulation of the electricity market. The deregulation affects the deployment of IT in many ways; new IT support is needed for many business processes, e.g. billing. The ever changing business environment challenges contemporary organizations to constantly get most value from their IT. The Chief Information Officer, CIO, is responsible for IT management which is a significant challenge today. This paper uses the Architecture Theory Diagram (ATD) for modeling the CIO's responsibilities. The ATD spans the concerns of the CIO and is based on consolidated knowledge from existing architecture theories and frameworks. This paper presents the result from a survey where the concerns stated in the ATD were prioritized by CIOs at European electric power industries. The result can be used by CIOs for benchmarking. A prioritized set of concerns can be used for communicating to the rest of the organization what is important and be used as a basis for IT investments decisions and determining strategy. This paper is based on a survey answered by CIOs in the European electric power industry in January and February 2005. The survey was answered by twelve supreme IT chiefs at Electric Power Industries in Europe. All the respondents come from different countries and ten of the respondents are members in Cigré. The respondents consist of 75 % CIOs and 59 % of all the respondents' reports directly to their CEO. Results from the survey indicates that "Developing strategies", "IT and business alignment", and "Information security" are the three most important concerns for the European CIOs' in general. Then it is a large gap down to the fourth most important concern, which is "Project management". The paper is concluded with recommendation on how companies can use this survey to focus and communicating their prioritizations. The survey has been conducted in cooperation with the CIO-group at Vattenfall, Cigré and the Department of Industrial Information and Control Systems (ICS) at the Royal Institute of Technology (KTH), Sweden.

Abstract [en]

This reference model for IT management responsibilities covers the most important aspects when modeling, analyzing and evaluating enterprise architecture, EA. The reference model can be employed to support IT management in their quest to make well-informed decisions, e.g. to derive architectural principles in order to obtain a proper scope for EA activities, measure the status of the current EA, follow up changes committed, and evaluate alternative EA scenarios. The model is based on extensive literature studies and has been tested in a series of empirical studies
