Approaches to the Ex-arte Evaluation of Information Systems (PDF)

Inhaltsangabe:Summary:
This paper critically reviews approaches for the evaluation of investments in information systems prior to their implementation. First, the ground for the review is prepared by examining characteristics of evaluation, information systems and value. A classification of 54 evaluation approaches identified in English and German literature is then presented. Examples of each class are reviewed and their advantages and drawbacks are discussed. Their use in evaluation practice is analysed through the examination of empirical studies and directions for future research are given. A complete overview of state-of-the-art evaluation approaches is given at the end of the paper.
