Zusatztext

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.Inhaltsverzeichnis:Table of Contents:1.INTRODUCTION12.THEMATIC BACKGROUND32.1Information Systems32.2Evaluation82.3Value133.CRITICAL REVIEW OF EVALUATION APPROACHES173.1Antecedents to the Review173.2Effect-Assessing Approaches203.3Effect-Locating Approaches333.4Discussion of Usability of Approaches414.EVALUATION IN PRACTICE514.1Review of Empirical Studies514.2Interpretation of Empirical Studies554.3Discussion and Future Research575.CONCLUSIONS60APPENDIX61Overview of Evaluation Approaches61Literature Search Strategy64REFERENCES65
