For organizations pursuing CMMI certification, including CMMI Level 3 or Level 5 appraisal, understanding these changes can help support process standardization, risk management, quality improvement, and organizational performance.
CMMI defines five maturity levels that describe an evolutionary path of increasingly organized and systematically mature processes:
Level 1: Initial – Processes are unpredictable, poorly controlled, and reactive.
Level 2: Managed – Projects have ensured that processes are planned and executed in accordance with policy.
Level 3: Defined – Processes are well characterized and understood, and are described in standards, procedures, tools, and methods.
Level 4: Quantitatively Managed – The organization and projects establish quantitative objectives for quality and process performance and use them as criteria in managing processes.
Level 5: Optimizing – An organization continually improves its processes based on a quantitative understanding of its business objectives and performance needs.
