Critical success factors are those limited areas where “things must go right” for a business or organization to survive. They are described as performance measures which are crucial in making certain that a successful project is implemented and closed out in organizations. Various authors in literature have highlighted what they deem as the most important success factors for project execution, and these have been filtered out to capture the most relevant ones to the built environment industry, being: time, cost, quality, and scope and risk management. Quality is not only one of the three dimensions of the project management triangle, but also considered the ultimate, for every delivery depends on it. Project stakeholders are those individuals that have a direct or indirect effect on the success or failure of a project and have varying opinions of what constitutes as a successful project. The listed success factors above will be discussed on this paper in accordance to how the most important construction project stakeholders view those specified factors. The purpose of this research article is to investigate, assess and determine the critical success factors in construction projects and to validate their impact on the views of construction project stakeholders.
