CMM 



10/17/08

CMM is a common sense application of software or business management and quality improvement concepts to software development and maintenance. It can also be called as a commonly developed guide for evolving towards a culture of engineering excellence, model for organization improvement. 28

Structure of CMM

Level 1 – Initial 





10/17/08

The software process is characterized as ad hoc, and occasionally even chaotic. Few processes are defined, and success depends on individual effort and heroics. The system depends on individuals.

31

Level 2 Repeatable 

Basic project management processes are established to track cost  schedule  and functionality. The necessary process discipline is in place to repeat earlier successes on projects with similar applications. 

10/17/08

32

Level 2 Repeatable Key Process Areas Requirement Management 

 



Software Project Planning  



Project Planning Estimations

Software Project Tracking and Oversight  

10/17/08

Contract User Requirement Document

Plan Vs Actual Reviewing , Analyzing and updating the Plan, if necessary 33

Level 2 - Repeatable Key Process Areas



Software Subcontract Management 

Maturity of the Subcontractors.   



Software Quality Assurance  



SQA is expected to review and verify all the activities SQAG is integral part of software engineering and management processes.

Software Configuration Management 

10/17/08

Requirement Management Project Planning Project Tracking.

To Ensure integrity of the product through out the Software development life cycle. 34

Level 3 - Defined 

  

10/17/08

The Organizational Level Process are defined both for Management and Engineering activities. Process Documents are Created. Standards are Defined All the projects use an approved , tailored version of OSSP for developing and maintaining software.

35
