CMMI Appraisal

The CMMI Appraisal is an examination of one or more processes by a trained team of professionals using an appraisal reference model as the basis for determining strengths and weaknesses of an organization.

CMMI assessments:

  1. Appraisal Requirements for CMMI (ARC) contains the requirements for three classes of appraisal methods Class A, Class B, and Class C. These requirements are the rules for defining each class of appraisal method.
  2. Standard CMMI Appraisal Method for Process Improvement (SCAMPI) Method Description Document (MDD): currently the only approved Class A appraisal method.

There are three classes of CMMI Appraisal Methods: Class A, Class B, and Class C.

SCAMPI Class A Appraisal

SCAMPI A is the most rigorous method and the only method that can result in a rating.You can expect following outcomes from a SCAMPI A:

  1. A Maturity Level rating or Capability Level ratings.
  2. Findings that describe the strengths and weaknesses of your organization’s process relative to the CMMI.
  3. Consensus regarding the organization’s key process issues.
  4. An appraisal database that the organization can continue to use to monitor process improvement progress and to support future appraisals.

SCAMPI Class B Appraisal

SCAMPI B provides options in model scope, but the characterization of practices is fixed to one scale and is performed on implemented practices.You can expect following outcomes from a SCAMPI B:

  1. Detailed findings that describe the strengths and weaknesses of your organization’s process relative to the CMMI.
  2. Practice characterizations indicating the likelihood that the examined practices would satisfy the goals and meet the intent of the CMMI.
  3. Consensus regarding the organization’s key process issues.
  4. A FIDO database that the organization can continue to use to monitor process improvement progress and to support future appraisals.

SCAMPI Class C Appraisal

SCAMPI C provides a wide range of options, including characterization of planned approaches to process implementation according to a scale defined by the user.SCAMPI C appraisals are often performed for reasons such as:

  1. Provide a quick gap analysis of an organization’s process relative to the CMMI.
  2. Assess the adequacy of a new process before it is implemented.
  3. Monitor the implementation of a process.
  4. Determine an organization’s readiness for a SCAMPI A.
  5. Support the selection of a supplier.
  1. Findings that describe the strengths and weaknesses of the assessed processes. Depending on the appraisal scope and strategy, findings may be mapped to the relevant CMMI components.
  2. Characterizations that summarize the adequacy of the assessed processes vis-?-vis the CMMI.
  3. Recommended process improvement actions.
  4. A FIDO database that the organization can continue to use to monitor process improvement progress and to support future appraisals.
