The Capability Maturity Model Integration (CMMI) defines a Process Area as, “A cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area.” Both CMMI for Development v1.3 and CMMI for Acquisition v1.3 identify 22 process areas, whereas CMMI for Services v1.3 identifies 24 process areas. Many of the process areas are the same in these three models
Process Area Organization
In CMMI models, the process areas are organized in alphabetical order according to their acronym. However, process areas can be grouped according to maturity levels or process area categories.
Maturity Levels: CMMI for Development
There are Five maturity levels. However, maturity level ratings are awarded for levels 2 through 5. The process areas below and their maturity levels are listed for the CMMI for Development model:
Maturity Level 2 – Managed
- CM – Configuration Management
- MA – Measurement and Analysis
- PMC – Project Monitoring and Control
- PP – Project Planning
- PPQA – Process and Product Quality Assurance
- REQM – Requirements Management
- SAM – Supplier Agreement Management
Maturity Level 3 – Defined
- DAR – Decision Analysis and Resolution
- IPM – Integrated Project Management
- OPD – Organizational Process Definition
- OPF – Organizational Process Focus
- OT – Organizational Training
- PI – Product Integration
- RD – Requirements Development
- RSKM – Risk Management
- TS – Technical Solution
- VAL – Validation
- VER – Verification
Maturity Level 4 – Quantitatively Managed
- OPP – Organizational Process Performance
- QPM – Quantitative Project Management
Maturity Level 5 – Optimizing
- CAR – Causal Analysis and Resolution
- OPM – Organizational Performance Management
Maturity Levels: CMMI for Services
The process areas below and their maturity levels are listed for the CMMI for Services model:
Maturity Level 2 – Managed
- CM – Configuration Management
- MA – Measurement and Analysis
- PPQA – Process and Product Quality Assurance
- REQM – Requirements Management
- SAM – Supplier Agreement Management
- SD – Service Delivery
- WMC – Work Monitoring and Control
- WP – Work Planning
Maturity Level 3 – Defined (this includes the process areas that make up the previous levels; Maturity Level 3 is made up of the process areas in Level 2 and Level 3)
- CAM – Capacity and Availability Management
- DAR – Decision Analysis and Resolution
- IRP – Incident Resolution and Prevention
- IWM – Integrated Work Management
- OPD – Organizational Process Definition
- OPF – Organizational Process Focus
- OT – Organizational Training
- RSKM – Risk Management
- SCON – Service Continuity
- SSD – Service System Development
- SST – Service System Transition
- STSM – Strategic Service Management
Maturity Level 4 – Quantitatively Managed
- OPP – Organizational Process Performance
- QPM – Quantitative Work Management
Maturity Level 5 – Optimizing
- CAR – Causal Analysis and Resolution
- OPM – Organizational Performance Management
Maturity Levels: CMMI for Acquisition
The process areas below and their maturity levels are listed for the CMMI for Acquisition model:
Maturity Level 2 – Managed
- AM – Agreement Management
- ARD – Acquisition Requirements Development
- CM – Configuration Management
- MA – Measurement and Analysis
- PMC – Project Monitoring and Control
- PP – Project Planning
- PPQA – Process and Product Quality Assurance
- REQM – Requirements Management
- SSAD – Solicitation and Supplier Agreement Development
