Over the last decade, information technology (IT) projects have continued to fail at an alarming rate. Project managers are still battling to manage and deliver successful IT projects in organizations. The conceptual information technology project management assurance framework developed consists of project assurance processes. The conceptual framework was validated through a survey of 121 IT project managers from organizations in seven African countries. The purpose of this paper is to present research findings on how well project assurance processes are implemented and their importance in achieving a successful IT project outcome in organizations. The findings indicate that most project assurance processes are implemented better in successful IT projects than in challenged and failed IT projects. The findings also indicate that in successful, challenged, and failed IT projects, project assurance processes were perceived to be important in achieving a successful IT project outcome. This paper contributes to the body of knowledge on project auditing and assurance. Practitioners and project managers can use the conceptual information technology project management assurance framework to deliver successful IT projects in organizations.
