Project management, as a profession and area of research, continues to grow and develop. In response to project management being applied in new countries, industries and application areas, the demands on project management continue to change. During the development, the analysis of characters or variables that are subsequently identified as facilitators or barriers to project success has enjoyed support from a growing community of researchers (Baker et al., 1988; Pinto & Slevin, 1988). An understanding of those factors is important for two reasons: It provides guidelines to the screening of projects and leads to insights into the manner in which projects should be managed. Among many studies of this kind, the relative importance of success factors, adjusted by environmental attributes such as economic, social, cultural, business sectoral, etc., is found to be a critical one (Belassi & Tukel, 1996).
