SEI Capability Maturity Model (CMM)
Operational/quality management maturity models by R. Likert, P. Crosby; software model by R. Radice; made popular by Watts Humphrey at Software Engineering Institute (SEI)
Goal: A level 5 maturity rating, implying continuous process improvement via defect prevention, technology innovation, and process change management
Approach: Five-level process maturity model defined. Maturity level assigned based on repeated assessment of performance in key process areas. Improvement achieved by action plans for processes assessed to be deficient.
Result: A set of well-defined key processes
5 Optimizing Continuous Process Improvement
4 Managed Product & Process Quality
3 Defined Engineering Process
2 Repeatable Project Management
