Mapping the Unified Process to CMMI

The (Rational) Unified Process (RUP or UP) is an iterative software development process. It was originally developed by the creators of UML at Rational Rose (now IBM).

CMMI (Capability Maturity Model and Integration) is a model that identifies the characteristics for a good software process within an organisation and defines metrics to be used to measure and improve the maturity of this process. CMMI is developed and governed by the SEI at Carnegie Mellon University. CMMI identifies 5 maturity levels:

1. Initial
2. Managed (reactive process)
3. Defined (proactive process)
4. Quantitatively managed (measured & controlled)
5. Optimizing

The table below how well the Unified Process implements the CMMI constellation for Development (CMMI-DEV). The table below groups the CMMI-DEV process areas by category. The higher the maturity level associated with a process area, the darker blue the background color is. For each process area we show how well UP covers this project area, using a crude High-Medium-Low classification. The table is based on data from SEI and from IBM.

CMMI Category	Process Area		Maturity level	UP support	UP remarks
Project Management	PP	Project Planning	2	High	only software aspects no data management
	PMC	Project Monitoring and Control	2	High	no data management
	SAM	Supplier Agreement Management	2	Low
	IPM	Integrated Project Management	3	Medium	weak integration of plans and managing dependencies between them
	RSKM	Risk Management	3	High	should add risk parameters
	QPM	Qunatitiative Project Management	4	Low	no process decomposition no statistical analysis
Engineering	REQM	Requirements Management	2	High
	RD	Requirements Development	3	High	should add allocating component requirements
	TS	Technical Solution	3	High	no alternative solutions no reuse/build/buy analysis
	PI	Product Integration	3	High
	VER	Verification	3	High	should add recording mechanism for reviews
	VAL	Validation	3	High
Support	CM	Configuration Management	2	High
	PPQA	Process and Product Quality Assurance	2	High
	MA	Measurement and Analysis	2	High	should add quantitative metrics and analysis
	DAR	Decision Analysis and Resolution	3	Low
	CAR	Causal Analysis and Resolution	5	Low	support for actions on defects and evaluation
Process Management	OPF	Organizational Process Focus	3	Low	basic support
	OPD	Organisational Process Defintion	3	Medium	basic support
	OT	Organizational Training	3	Low
	OPP	Oprganisational Process Performance	4	Low
	OPM	Organizational Performance Management	5	Low
