3. INTRODUCTION TO CMM :-
CMM : Capability Maturity Model
CMM was developed by software engineering institute in
1986.
Framework that describes the key elements of an
effective software process.
4. What are the levels of CMM?
Initial
Repeatable
Defined
Managed
Optimising
5.
6. Level 1:- Initial
Team tackles projects in different ways each time.
Can have strong successes, but may not repeat.
Success comes from smart people doing the right things.
Hard to recover from good people leaving
Most S/W development organizations are Level 1.
7. Level 2 :- Repeatable
Realistic project commitments based on results
observed on previous projects.
Software project standards are defined and faithfully
followed
Processes may differ between projects.
earlier successes can be repeated
8. Level 3 :- Defined
The software process for both management and engineering
activities is documented, standardized, and integrated into a
standard software process for the organization.
All projects use an approved, tailored version of the organization’s
standard software process for developing an maintaining software.
9. Level 4 :- Managed
Detailed measures of the software process and product
quality are collected.
Narrowing the variation in process performance to fall within
acceptable quantitative bounds
When known limits are exceeded, corrective action can be
taken.
Quantifiable and predictable
10. Level 5:- Optimising
Continuous process improvement is enabled by quantitative
feedback from the process and from piloting innovative ideas
and technologies.
Goal is to prevent the occurrence of defects.
Data on process effectiveness used for cost benefit analysis of
new technologies and proposed process changes
11. It is a goal, not a method.
Being used just as stamp of approval.
Doesn’t say anything about software.
Doesn’t help in a crisis.
