What model defines five levels of project management maturity?

The Project Management Maturity Model (OPM3) is the correct answer because it specifically outlines five levels of maturity in project management practices, which are essential for organizations seeking to improve their project management capabilities. These levels—initial, structured, managed, measurable, and optimizing—allow organizations to assess their current project management practices and identify areas for improvement. The model serves as a roadmap for enhancing project management processes and integrating them into the organization’s strategic goals.

This structured approach aids organizations in understanding where they currently stand in their project management practices and guides them in progressing toward higher maturity levels, which can lead to improved project outcomes, better resource management, and more effective achievement of business objectives. By focusing on these maturity levels, organizations can implement targeted improvements and ultimately enhance their overall project management competency.
