An integrated Information Technology/Information System (IT/IS) Investment Evaluation Framework

This paper presents an integrated IT/IS investment evaluation framework based on IT/IS investment evaluation and business values and IS Success factors. The proposed framework involves different parts of organization or stakeholders whom are influenced by IT/IS investment decisions. It uses Delphi technique for selecting and grouping IT/IS investment criteria. Then, selected criteria are weighted by Analytical Hierarchy Process (AHP) technique. Finally, Data Envelopment Analysis (DEA) technique is used for determining the efficient and inefficient alternatives or decision making units (DMUs). This framework is more advanced, practical and reliable than current techniques for IT/IS investments. The framework is applied to a large gas refinery and the results showed its ease of use and applicability
