  2. SEI Maturity Model for Software Process • A maturity level is a well-defined evolutionary plateau towards achieving a mature process. • Each maturity level provides a layer in the foundation for continuous process improvement. • Each level comprises a set of process goals that stabilize an important component of the software process. • Achieving each level of the maturity framework establishes a component in the process, resulting in an increase in the process capability of the organization.

  3. Organization maturity levels (stages) Optimizing Continuously (5) improving process Managed Predictable (4) process Defined Standard, Progreff (3) consistent process Repeatable Disciplined (2) process Initial (1)

  4. Driving force: Quality Improvement

  5. Visibility improve for each level 5 In Out 4 In Out 3 In Out 2 In Out 1 Out In

  6. Performance continuously improves in Level 5 organizations Based on quantitative understanding of process and product, performance continues to improve in Level 4 organizations With well-defined processes, performance improves in Level 3 organizations Plans based on past performance are more realistic in Level 2 organizations Schedule and cost targets are typically overrun by Level 1 organizations. Predictability increases 5 Time/$/... 4 Time/$/... 3 Time/$/... 2 Time/$/... 1 Time/$/...

  7. Maturity Model Hierarchy Maturity Levels contain Key Process Areas contain Common Features contain Key Practices
