The CMMIŽ (Capability Maturity Model Integrated) is a repeatable capability assessment method produced by Software Engineering Institute for the US Department of Defence.The CMMIŽ (the evolution of the Capability Maturity Model, or CMM) was originally created to enable the US DOD to assess the capability of supplier software organisations. It’s use has since spread to be used by organisations who just wish to be better, more consistent and therefore gain the edge on the competition. The CMMIŽ is not just an assessment method it is a capability map, describing the specific goals and practices that an organisation requires to reach a level of capability and maturity. The CMMIŽ has two representations that are essentially two different views of the same process areas.
CMMIŽ is registered in the U.S. Patent and Trademark Office by Carnegie Mellon University.
The staged representation organises process areas into maturity levels. This is the preferred method for TCP to adopt to address CMMi requirements. Each maturity level provides a grouping of process areas that have to be achieved in order to achieve that level of maturity.

Processes are progressively improved and measured against the CMMi performance measures, from an initial stage with an Adhoc application of processes.
In the continuous model, each process area is profiled individually by capability. With this representation an organisation can have a capability profile that shows each of the process areas at different levels of capability.

The logic behind the continuous model is that process areas considered important to an organisation can be improved in isolation from other process areas – although in practice this is rarely the case.
