CAPABILTY MATURITY MODEL(CMM)

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.

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 of maturity and then to work towards that level.”

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.

REPEATABLE MATURITY LEVELThis 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.

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.

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.

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.
