What framework includes five levels for measuring project management maturity?

The Operational Project Management Maturity Model (OPM3) is specifically designed to assess and enhance an organization's project management capabilities. It provides a structured framework that outlines five distinct levels of maturity, enabling organizations to evaluate their current project management practices and identify areas for improvement.

These maturity levels in OPM3 guide organizations through a progressive path, starting from an initial, ad-hoc level of project management practices to achieving optimized and standardized processes. By using OPM3, organizations can develop a strategic approach to enhance their project management processes, ensuring that they not only complete projects successfully but also align with broader organizational goals.

This model emphasizes the importance of continuous improvement and offers a roadmap for organizations to advance their project management maturity systematically. While other options offered in the question pertain to project management in various ways, OPM3 is noted for its specific focus on the maturity assessment and development in the context of operational project management.
