CMMI Details
What It Is
Capability Maturity Model Integration (CMMI) is a globally recognized process improvement framework developed by Carnegie Mellon’s SEI and now governed by ISACA. Its primary purpose is to help organizations institutionalize effective processes for predictable, high-quality delivery in development, services, and acquisition. CMMI uses a maturity-based approach with staged or continuous representations to benchmark and advance capability.
Key Components
- 25 Practice Areas in v2.0, grouped into 4 Category Areas: Doing, Managing, Enabling, Improving.
- 6 Maturity Levels (0-5) from incomplete to optimizing.
- Generic practices for institutionalization (policy, planning, measurement).
- SCAMPI appraisals (A/B/C) for certification and benchmarking.
Why Organizations Use It
- Drives predictability, quality, and ROI (e.g., reduced rework, 4:1 ROI).
- Meets contractual requirements in defense, regulated sectors.
- Mitigates risks via measurement and continuous improvement.
- Builds competitive advantage and stakeholder trust through published ratings.
Implementation Overview
Phased approach: gap analysis, piloting, rollout, appraisal. Suited for mid-to-large orgs in IT/software/services globally. Involves training, tooling, change management; SCAMPI A for official maturity ratings. (178 words)
