Abstract: The purpose of this research was to define and examine the various variables that affect Decision Support Systems (DSS) usage in evaluating and selecting information system (IS) projects and defined the most severe problems that could face decision-makers when they use DSS. The unit of analysis for this research was the senior experts, head of offices, deputies, and top, middle and lower level managers in National Iranian Gas Company headquarter staff. Questionnaire developed to generate a representative sample of items and achieve content validity. After the internal consistency examined, a multiple regression analysis undertook to examine the relationship between DSS usage in evaluating or selecting the IS projects as a dependent variable and affecting variables in DSS usage as independent variables. Results showed that the variables together explained 32.8 percent of DSS usage in evaluating and selecting of IS projects and just variable “Ease of use” having a significant impact on DSS usage.
