Abstract [en]

In this paper an approach to develop and refine a functional reference model for IT-systems is presented. Such reference models form a fundament on which to evaluate the business value of IT systems. The approach involves scrutinizing the functional reference model with respect to correctness, completeness, granularity and measurability. In the particular case of this study, the functional reference model represents systems functionality needed to support asset management processes in industries such as electric energy production and distribution. It is based on the IEC 61968 standard and its Interface Reference Model, IRM, which has been refined in the process described in the paper. The refinement included a comprehensive field study, interviewing experts in the field of asset management at a large European energy company, as well as vendors of asset management systems.A general method for evaluating IT investment scenarios is outlined in the paper and the refined functional reference model is an important component in this method. Creation of this IT evaluation method is an ongoing research project, where the functional reference model forms a central part. The purpose of the IT investment evaluation method is to give decision makers a tool to evaluate potential investment scenarios with respect to the value the investment would generate to the business. The first part of the method consists of evaluating the technical quality of the system scenarios. Technical quality is divided into functional and non-functional attributes, where the functional reference model is used for the functional assessment. The second part of method consists of establishing the business value based on the evaluation of the technical qualities. This paper thus focuses on the first part, and in particular the development of the functional reference model which is a central piece in the IT investment evaluation method.

Abstract [en]

s the dependence of IS/IT has grown in modern organizations, IT investments have soared in the last couple of decades. Large amounts of money are spent with the hope that the investments will generate value for the business organizations using the systems. It is hence easy to understand the needs for methods to assess the business value of IT-investments. The investment decision is basically about selecting the best IT-system or the best combination of IT-systems, i.e. the system(s) that provides the most business value in dimensions that are important business-wise. However, a problem with many of the avail-able methods is that they often fail to concretely explain what technical characteristics the IT systems(s) should have to achieve the business value desired. A complicating aspect of IT-investment evaluations is also that the evaluations usually include a high degree of un-certainty.

In this thesis, an IT investment evaluation method is presented that indicatively assesses the differences in contribution to business value from IT-investment alternatives. The method provides, at a relatively low cost of investigation, indications of not only the technical differences between the IT-investment alternatives in a specific investment situation, but also an assessment of the differences in types and amounts of their business value. The presented method has been applied in a large case study at an electric power company. Furthermore, it also incorporates concepts found within Enterprise architecture (EA), particularly in how the information used in the evaluation is collected.

The presented thesis is a composite thesis that, besides an introduction, includes five papers (paper A-E). Paper A presents an outline of the method as well as its application in the case study. It also presents the theoretical fundaments for the criteria used for the technical evaluation and the business value assessment including the method’s applications in relation to Enterprise architecture. The following two papers primarily present necessary steps in the development of the method. First, paper B presents the process to develop a functional reference model (used for the functional assessments in the method), including its application in the case study. Second, a breakdown of the term business value into a set of IS/IT-affected value dimension is presented in paper C. The last two papers present the final steps, i.e. the technical evaluation of the investment alternatives (paper D) and the final business value assessment (paper E). The papers include the methods to perform these analyses as well as the application of the method in the case study and the results of the case study.
