Capability maturity model

Software engineering

1. OVERVIEW OF SEI - CMM

2. Cmm  Capability Maturity Model: Its created by the SEI(Software Engineering Institute), a research center founded by Congress in 1984. A structure designed to direct IT organizations through improvement. Philosophy of “ Continuous Process Improvement”.

3. What is CMM?: CMM is a method of assessment used to develop and refine the software development process used by organizations. Based on: - Management styles using quantitative methods. - Five level Capability Model.

4. Evolution of cmm : Original release of software engineering CMM in 1993 . After this more variants were developed. Tailored to fit a particular organization ->System Engineering CMM (SE-CMM). ->Trusted CMM (T-CMM). ->Security System Engineering CMM (SSE-CMM). ->People CMM (P-CMM ). ->Integrated Product Development CMM (IPD-CMM).

5. GOALS OF CMM: Provide an organization with the framework for improving its processes and its ability to manage the development ,acquisition and maintenance of products or services. This provided through appraisals and assessments of the organizations processes based on CMM criteria. Provide ” Clients ” with a maturity scale rating for potential vendors. The more mature an organization (Higher CMM Rating) , the more likely its processes and development are to succeed.

6. Motivation to cmm / cmmi : In the 1980’s military projects ran over budget. United states Air Force funded SEI study. The model CMM was being used for software development ,but problems were found when multiple instances of CMM were being used. CMMI was created to address this issue . CMMI is Capability Maturity Model Integrated .

7. CMM – Designed with software in Mind: DESIGN GOALS These do not focus on the customer. ORGANIZATION IMPROVEMENT  Improve methods and process. KEY PROCESS AREAS  Initial, Repeatable, Defined, Managed, Optimizing. Planning and management oriented.

8. Cmm vs iso : CMM :  Continuous process improvement.  Scope – Software.  Customer satisfaction is not part of CMM.  Concept – Best practices derived from industry leaders and a rating system.

9. Iso :  Acceptable quality system.  Scope – Hardware , Software , Processed Materials and Services.  Customer satisfaction is important in ISO requirements.  Concept – Certification tool.

10. Levels of cmm :

11. Focus areas and key process areas:

12. Summary: CMM allows process improvement in organizations. Can have huge benefits if level 5 is achieved. Should be used as a tool that is adapted to an organization.
