What is cmmi


  • Capability Maturity Model - Integration

Cmmi appraisal types 1

CMMI Appraisal Types .1

  • Continuous

    • Pick and choose desirable process areas

    • Capability level 0-5

    • Capability level can be achieved without performing all practices

    • Not industry recognized

    • Primary appraisal method in India

    • 1 – 3 weeks to perform appraisal

Cmmi appraisal types 2

CMMI Appraisal Types .2

  • Staged

    • Maturity level

    • Level 1-5 (everyone is level 1)

    • All practices must be met for achieving the maturity level

    • Rating is for 3 years and then expires

    • Rigorous review of processes and artifacts

    • 2-4 weeks to perform appraisal

Specific versus generic

Specific versus Generic

  • Specific practices are process area dependent

    • (4 – 12 based on process area)

  • Generic practices are the same across all process areas

    • (10-12 practices based on level)

  • All SP’s and GP’s require same level of artifact coverage

Cmmi measures process maturity

CMMI Measures Process Maturity

  • 25 Process Areas in 4 general categories:

    • Process management (5 process areas)

    • Project management (8 process areas)

    • Engineering design (6 process areas)

    • Support functions (6 process areas)

The measurement is the achievement of a limited number of Specific Goals in each process area, plus Generic Goals which apply to each process area.

Generic practices

Generic Practices

  • Identify and involve relevant stakeholders

  • Monitor and control the process

  • Objectively evaluate adherence

  • Review status with higher level management

  • Establish a defined process

  • Collect improvement information

  • Organizational policy

  • Plan the process

  • Provide resources

  • Assign Responsibility

  • Train the people

  • Manage configurations

Direct versus indirect

Direct versus Indirect

  • Direct artifacts required for each SP and GP

    • Supporting artifact or resultant artifact of creating the direct artifact



  • Verbal confirmation of what the process definition

  • Interview process
