CMMI Details
What It Is
Capability Maturity Model Integration (CMMI) is a performance improvement framework governed by ISACA, originating from the Software Engineering Institute. It defines process maturity for software development, services, and acquisition through structured practice areas and progression levels. The core approach emphasizes institutionalization via specific practices and generic goals for repeatable, measurable outcomes.
Key Components
- 25 Practice Areas grouped into 4 Category Areas (Doing, Managing, Enabling, Improving)
- Maturity Levels 0-5 (staged) or capability levels per area (continuous)
- Generic Practices (e.g., policy, planning, monitoring) for sustainment
- SCAMPI appraisals (Class A/B/C) for validation
Why Organizations Use It
- Achieves predictability, reduces rework (up to 50% schedule gains)
- Meets defense/contractual mandates, builds procurement eligibility
- Enhances risk management, quality, customer satisfaction
- Provides competitive benchmarking and stakeholder trust
Implementation Overview
- Phased: gap analysis, pilots, training, rollout, appraisal
- Integrates with Agile/DevOps via tailored processes
- For mid-large IT/software firms globally
- Requires authorized SCAMPI Class A for ratings
IATF 16949 Details
What It Is
IATF 16949:2016 is the international quality management system (QMS) standard for automotive production and relevant service parts organizations. It builds on ISO 9001:2015 with automotive-specific requirements, focusing on defect prevention, variation reduction, and supply chain consistency via a process-based, risk-thinking approach aligned with PDCA.
Key Components
- Clauses 4-10 mirroring ISO 9001, plus supplements like core tools (APQP, FMEA, PPAP, MSA, SPC, Control Plans).
- Over 30 automotive additions covering product safety, CSRs, supplier management, warranty systems.
- Built on 7 quality principles; requires third-party certification by IATF-approved bodies with rules for audits.
Why Organizations Use It
- Contractual OEM prerequisite for supply chain access.
- Reduces COPQ, warranty costs, recalls via prevention.
- Enhances competitiveness, stakeholder trust, operational efficiency.
Implementation Overview
- Phased: gap analysis, core tool deployment, training, audits.
- Applies to automotive sites/suppliers globally; 12-18 months typical.
- Involves leadership commitment, process ownership, certification audits.
Key Differences
| Aspect | CMMI | IATF 16949 |
|---|---|---|
