The Capability Maturity Model (CMM) was developed starting in 1984 by Watts Humphrey and the Software Engineering Institute to help the Department of Defense compare and measure its software contractors. The CMM defines 5 levels of process maturity for software development organizations: 1) Initial, 2) Repeatable, 3) Defined, 4) Managed, and 5) Optimizing. It provides a framework for organizations to assess their software processes and work to continuously improve them.

2. INTRODUCTION:
The CMM was developed from 1984 by
Watts Humphrey and the Software Engineering
Institute(SEI). The SEI is a part of Carnegie Mellon
University. The work was funded and continues to
be funded by the Department of Defense(DoD),
which was originally looking for ways to compare
and measure the various contractors that were
developing software for the DoD.

3. Meaning :
“A Capability of Maturity Model(CMM) is a formal archetype of the levels through which an
organization evolves as it defines, implements , measures, controls and improves its processes in a
particular area of operation. It thus enables the organization to consciously choose a certain target level
ofmaturityandthen toworktowardsthatlevel.”
Definition:
“The definition implies that the CMM concept is mainly applicable to
organizational processes, such as development processes or business processes. This
process orientation underlies the model described in this paper and thus with
knowledge within the framework of business processes.

6. REPEATABLE MATURITY LEVEL
This level of Software Development
Organization has a basic and consistent
project management processes to track cost,
schedule and functionality. The process is in
place to replace the earlier successes on
projects with similar applications. Program
management is a key characteristics of a level
two organization.

7. DEFINED MATURITY LEVEL
The software process for both management
and engineering activities and documented,
standardized and integrated into a standard
software process for the entire organization
and all projects across the organization use
an approved, tailored version of the
organization’s standard software process for
developing, testing and maintaining the
application.

8. MANAGED MATURITY LEVEL
Management can effectively control the
software development effort using precise
measurements. At this level, organization set
a quantitative quality goal for both software
process and software maintenance. At this
maturity level, the performance of processes
is controlled using statistical and other
quantitative techniques and is quantitatively
predictable.

9. The key characteristics of this level is focusing
on continually improving process performance
through both incremental and innovative
technological improvements. At this level
changes to the process are to improve the
process performance and at the same time
maintaining statistical probability to achieve the
established quantitative process - improvement
objectives.
