When measuring process capability, the CMMI "continuous representation" is used. In the continuous representation, each process area is assigned a capability level as follows :
Capability Level 0: Incomplete
Capability Level 1: Performed
Capability Level 2: Managed
Capability Level 3: Defined
Capability Level 4: Quantitatively Managed
Capability Level 5: Optimizing
In the CMMI continuous representation, capability level profiles are used to depict the list of process areas and their corresponding capability levels. Achievement profiles represent the current state and target profiles represent the desired state. The SCAMPI assessment method is also used for formal determination of an organization's achievement capability level profile.
