  1. SEI White Paper: Process Maturity Model Present by Hui Huang November 16, 2000 ® CMM is Registered in the US Patent and Trademark Office

  2. Overview of the article(CMM for Software) • Overview of CMM • Background discussion: Why CMM is crucial • Developing History • Detailed Summary • Description of Uses for • Process Improvement • Evaluation of software supplier • Pros and Cons • State of Practices and Future Directions

  3. Clarification of Terms • Software process • Software process capability • Expected results • Software process performance • Actual results • Software process maturity

  4. What is CMM ? • A SEI Patent • A Five-Level Hierarchical Model • A set of known GMPs and an improvement strategy for building consistent and predictable software products

  5. Why CMM is crucial • Determine the current process maturity level • Identify a vital few issues • Focus on limited set of activities • Enable steady, continual and lasting gains

  6. Maturity Levels in CMM

  7. Key Process Areas (KPAs) • Each KPA identifies a cluster of related activities that achieve a set of goals considered important for process capability • The path of a key process may differ

  8. The IDEAL approach to using the CMM • The five phase of the IDEAL approach • I: Initiating (the groundwork) • D: Diagnosing (the distance to the goal) • E: Establishing ( the plan) • A: Acting (doing the work) • L: Learning (from the experience) • CMM is part of the IDEAL approach

  9. Cons: • CMM is Not comprehensive • non-software disciplines are not addressed • Counter-argument: CMM is deliberately focused on software process • CMM is Difficult to Understand • The solution is for Large organization • The maturity levels oversimplifies issues • The KPAs are static

  10. Pros • Normative components are short: 18 KPAs and 52 Goals organized in hierarchical model • CMM has been reviewed by many software developers and has many successful applications • Training available from SEI and authorized distribution partners

  11. State of the Practices • In 1989, 90% of the organization assessed are at level one and only 1 at level 5 • In 1999, >70 of the organization assessed are at level 4 or 5 • Commercial Users: 60% • Government/Military Users: 40%

  12. Suggested Reading • Paulk Mark et al. 1995 The Capability Maturity Model: Guidance for Improving the Software Process Questions ?
