Abstract Ämnesord
  • 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.
