CMM OVERVIEW

• CMM(Capability Maturity Model )
• Developed by Software Engineering Institute
• Describes the principles and practices underlying
  software-process maturity
• Help organizations improve the maturity of their
  software processes
• Help customers to identify the strengths,weakness
  and risks associated with their software
  suppliers

3
CMM Five Level

• Five levels
• Initial
• Repeatable
• Defined
• Managed
• Optimizing
• Each level has a set of key process areas
• Each key process area comprises a set of key
  practices

4
Key process areas in the CMM
level Key Process Areas
5 Optimizing Defect prevention Technology change management Process change management
4 Managed Quantitative process management Software quality management
3 Defined Organization process focus Organization process definition Training program Integrated software management Software product engineering Intergroup coordination Peer reviews
2 Repeatable Requirements management Software quality assurance Software project tracking and oversight Software project planning Software subcontract management Software configuration management
1 Initial

5
Organization of key practices

• Common features
• Commitment to perform
• Ability to perform
• Activities performed
• Measurement and analysis
• Verifying implementation

6
CMM key practices

• Describe
• what actions must the organization take to ensure
  that the process is established and will endure
• what preconditions must exist to implement the
  software process competently
• what roles and procedures are necessary to
  implement a key process area
• what procedures are needed to measure the process
  and analyze the measurements
• what steps are needed to ensure that activities
  are performed in compliance with the established
  process

7
ISO 9000 OVERVIEW

• ISO 9000
• Developed by Intl Org. for Standardization
• Specify quality-system requirements
• ISO 9000-3 guidelines for applying ISO 9001
• Demonstrate suppliers capability to design and
  supply a product
• Ensure that the supplier conforms to specified
  requirements during several stages of development

Mapping Summary

• Every CMM key process area is at least weakly
  related to ISO 9001 in some way
• Every CMM key process area at level 2 is strongly
  related to ISO 9001
• High degree of overlap
• Rigid mapping is impractical
• Although the CMM does not adequately address some
  specific issues, in general it encompasses the
  concerns of ISO 9001, but the converse is less
  true

13
Compare Conclusion

• Common
• Similar issues
• quality and process management
• Same bottom line
• Say what you do Do what you say

14
Compare Conclusion

• Difference
• CMM
• More detailed guidance and software
  specificity
• Explicit emphasis of CMM on continuous
  process improvement
• Focuses strictly on software
• ISO 9001
• High level of abstraction
• Address only the minimum criteria for an
  acceptable quality system
• Has a much broader scope that encompasses
  hardware, software,
• processed material and services

15
Compliance Issues

• At first glance, an organization with an ISO 9001
  certificate would have to be at level 3 or 4 in
  the CMM. In reality, some level 1 organizations
  have been certified
• ISO 9001s high level of abstraction
• ISO 9001 doesnt address all the CMM
  practices.
• An auditor may not require mastery to
  satisfy the
• corresponding ISO 9001 clause
• Obtaining ISO 9001 certification should be
  relatively straightforward for a level 2 or
  higher organization.

16
CMM or ISO 9001

• Whether software process improvement should be
• based on the CMM or ISO 9001?
• CMM is the better choice for structuring a
  process- improvement program
• In order to build a competitive advantage, we
  need consider both
• continuous process improvement total
  quality management
•

This analysis is subjective,but I hope it is
objective enough to be worthwhile
