What is the main purpose of using a maturity model like CMMI or PPM across projects?

• A. Provide a structured path to improve processes, capability, and performance.
• B. Eliminate governance structures.
• C. Guarantee zero defects.
• D. Force uniform project size.

Answer: (C)

The main idea is establishing a repeatable path for improving how work is done across projects. A maturity model like CMMI or PPM provides staged levels of capability with defined practices at each level, so an organization can steadily raise its process maturity, improve capability, and boost performance and quality over time. It also creates a common language, measurement, and governance that help align efforts, benchmark progress, and guide improvements across multiple initiatives rather than relying on ad hoc luck or individual teams. Eliminating governance structures isn’t what these models aim for; governance is what keeps improvements aligned with strategy and ensures consistent application across projects. Guaranteeing zero defects is unrealistic because even mature processes can produce defects; models improve predictability and quality, but cannot promise perfection. Forcing uniform project size isn’t a goal either—the value lies in standardized processes and outcomes, not in making all projects the same size.
