Your take-away from our conversation is generally correct on how CMMi differs or can benefit from ITIL components. They can help with developing a Service mindset including
- Market Analysis
- Demand Analysis
- Focus on Customer Experience, product / service processes (e.g. Help desk) & product / service marketing
- Performance analytics and auditing (in Operations)
CMMI focuses on product development excellence not service or building customer relationships and brand loyalty.
CMMI Level 2 includes:
- Requirements Management (but not Requirements Development which is Level 3)
- Project Management lite (called project monitoring and control but not the full PMI Project Management discipline which is in Level 3)
- Supplier Agreement Management (full Supplier Management is in Level 3)
- Measurements and Analysis (Applying analytics is in Levels 3-4-5)
- Process and product Quality
- Configuration Management
Level 3 is Program Management capabilites and also includes
- Verification & Validation (but not Service as defined by ITIL)
- Training
- Risk Management
- Technical development
- Training
- Organizational Environment for Integration (which is an attempt at devops)
