In this ever changing business structure, Intelligent Business System (IBS) is one of the survivals of a company, and the functions of information technology (IT) are becoming increasingly important. Evaluating the appropriate IBS for required conditions is the critical strategic decisions in formulating a business strategy. Although a number of factors were found to be influential in the choice of IBS. IBS evaluation is an inherently uncertain activity. To deal with the uncertainty in decision making, a fuzzy multi criteria decision making (FMCDM) method is adopted. This study presents an empirical approach of BIS evaluation and a real life evaluation process is presented to illustrate the effectiveness of the approach.
