Project managers’ behavior has been found to positively influence project outcomes we explore the issue through the development of a two-stage model incorporating agency theory that examines the relationship between PM behavior and IS project success. We measure project success by delivery on time, within budget, and adhering to specification. A web-based survey was used to collect data and test the model using SEM. The two-stage model was supported, however, further analysis suggests that a combination of three factors commitment, willingness, and motivation would significantly improve the model fit by forming a higher-order factor we call drive. We found that PM’s participation level is the most important factor influencing project success and is directly influenced by incentives and drive.
