The objective of this study is to identify the adherence of the Information Systems (IS) to the variables of an experiment based on business games. This relation was measured by means of the companies financial performance indicator ROE - Return on Equity. A multi-case study method was adopted to compare seven companies. Six out of seven developed an ISs - Information System. A strong adherence of the IS to the variables of the experiment and the performance reached by the companies was observed. The results reinforce the Fritzsche, Rodich and Cotter's (1987) research discoveries, pointing to a direct relation between the use of Information Systems and the financial performance measured by ROE.
