This study examines the evolving conceptualization of project success, with a particular emphasis on the roles of power skills and organizational culture within contemporary project management frameworks. In the past, project success was typically gauged by the "iron triangle" parameters of time, cost, and scope. However, in light of the evolving business environment and mounting societal expectations, the criteria for success have expanded to encompass additional dimensions, including stakeholder satisfaction, sustainability, and strategic alignment. This research is based on an extensive literature review, a cross-industry survey, and interviews with experienced project management professionals, which together illuminate a transition toward a more comprehensive success paradigm.
