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. In order to analyze all factors simultaneously, a project environment model is proposed. To test the research model, a questionnaire survey is conducted in 2012 summer and structural equation modeling (SEM) is used at analyzing
stage. Analyzes showed that there four main factors which are forming project environment; these are Strategic Support (1), Operational Support (2), Project Performance (3), and Organizational Success (4). As a result of the
analysis, strategic support enables more effective operational support. With effective operational support, project performance increases. Organizational success is affected by both project performance and strategic support directly, whereas the effect of operational support is indirect.
