has become one of the hottest topics in management, with practitioners and researchers demonstrating keen interest in the field (Ika, 2009). Thus, project management is emerging as a true scientific discipline in its own right, with its own academic journals, conferences, language, associations, periodicals, and its claim to a particular scientific status (Packendorff, 1995; Shenhar & Dvir, 2007). Yet, in a paradoxical way, despite such scientific activity, an ever-increasing number of bodies of knowledge and their periodic updates, the tireless efforts of practitioners, delays, cost overruns, underperformance in terms of quality, user satisfaction, and achievement of strategic or business objectives, as well as disappointment on the parts of project stakeholders, all seem to have become the rule and not the exception in the contemporary reality of projects (Cicmil & Hodgson, 2006a; Ika, 2009; Shenhar & Dvir, 2007). Consequently, "from a research perspective, there is a great opportunity to close this gap (between practice and research)," and as such, the project management field is promising and rich with challenges (Shenhar & Dvir, 2007, parentheses added, p. 93). Ironically, such promise closely matches the rising criticism of the research in the field (Söderlund, 2004a). In this respect, some authors have singled out certain scant or fragmented theoretical background and, not surprisingly, one of the responses to this criticism has been to investigate the theoretical underpinnings of the project management field (
