Abstract

This paper presents an interactive procedure with incomplete information for supporting corporate strategic information systems planning (SISP), which is based on a prescriptive group decision-making method showing how to aggregate experts' incomplete preference judgments. The system, named CoSIS, is suggested on the competency leverage concept for selecting technical or organizational enablers to attain organizational business objectives. We put the competencies between the objectives and enablers, measure the importance rates of competencies on the objectives, and derive target enablers for the company. The importance of a competency is calculated using the SISP experts' incomplete preference information regarding relationships of importance rates between competencies on each objective. The Web-based architecture of CoSIS makes it relatively easy for the SISP team to obtain this preference information from distributed experts. Using the system, we carry out the experiments for performance evaluation of our procedure.
