Q. Show the Different levels of CMM?

1) Initial (maturity level 1)-At this the lowest level there are fundamentally no sound software engineering management practices in place in the organization. In its place everything is done on adhoc foundation. In maturity stage 1 organization the software process is impulsive.

2) Repeatable (maturity level 2)-At this level policies for supervision a software project as well as procedures to implement those policies are established. Planning as well as managing new projects is based on experience with alike projects. A goal in achieving level 2 is to institutionalize effectual management processes for software projects which permit organizations to repeat successful practices developed on other projects. The software process ability at level 4 organizations can be summarized as disciplined.

3) Defined (maturity level 3)- At this stage the standard process for developing as well as maintaining software across the organization is documented including both software engineering and management processes. Processes established at stage 3 are utilized to help the software managers and technical staff to carry out more effectively. The software process capability at level 4 organizations can be concise as standard and constituent.

4) Managed (maturity level 4) at this stage the organization sets quantitative quality objectives for both software products and processes. Productivity as well as quality are measured for important software process activities across each projects as part of an organizational measurement program. The software process capability at stage 4 organizations is able to be summarized as "predictable".

5) Optimizing (maturity level 5)-At this level the whole organization s focused on continuous process improvement. The organizations have denotes to identify weaknesses and strengthen the process proactively with the goal of preventing the incidence of defects. . The software process capability at stage 4 organizations can be summarized as continuously improving.
