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.
