Organizations not only need to adapt themselves to fast evolving environment, but also endeavor to shape it for their survival. Executing projects is one of the important practices for handling difficulties created by changes taking place. Thus, almost all organizations, at any scale, implement a number of projects simultaneously all the time. Yet, executing projects does not ensure success. Thus, in this paper, the links between project success factors and project performance and strength of the relationships between the support factors and the success factors are studied and demonstrated to shed some light on project environment.
