Abstract
Almost all project management software has lack of displaying the outcomes of projects as a feature. This is because there is no recognized way of calculating the actual project duration compared to the authorized project duration. Data were collected through a mixed method using a Critical Incident Technique (CIT) and a survey. The study finds that time error can occur throughout the project execution phase. Findings suggest that challenged projects could be successful or failed projects using a model of IT Project Outcomes Testing (MITPOT). Thus, this model establishes a foundation of Project End Theory (PET).
