There is an expansion in the project management field as increased number of companies are becoming more “project-oriented” and are following and using technical knowledge in building the business models to help them their chances of success. In practice, many factors contribute to the success of project implementation. However, it is necessary to define the critical ones. Critical success factors (CSF) are extremely crucial as any organization is obliged to know which critical factors are utmost accountable and are the driver towards project success. Therefore, this research provides an overview of the requisite success elements of a project in order for it to be profitable and to dispose of the chance of failure. The study concentrates in the construction related project in the Sultanate of Oman. It reviewed the existing literature and hence, we identified nine critical success factors clusters that were critically analyzed via an online survey that was distributed to 120 different practitioners working at different companies in Oman with a respondent rate of 47.5%. Further, the survey asked respondents to rank specific sets of factors that leads to project failure. By the response, it is revealed that factors related to defining a project scope clearly (clear project definition) and team motivation to achieve project goals (competent project team members) are critical factors for a project to achieve its success among the other defined CSF. Further, the results show that inadequate planning is the most commonly encountered factor leading to failure in construction related projects in Oman.
