Standard CMMI Appraisal Method for Process Improvement


The Standard CMMI Appraisal Method for Process Improvement is the official Software Engineering Institute method to provide benchmark-quality ratings relative to Capability Maturity Model Integration models. SCAMPI appraisals are used to identify strengths and weaknesses of current processes, reveal development/acquisition risks, and determine capability and maturity level ratings. They are mostly used either as part of a process improvement program or for rating prospective suppliers. The method defines the appraisal process as consisting of preparation; on-site activities; preliminary observations, findings, and ratings; final reporting; and follow-on activities.

Class A, B, and C Appraisals

The suite of documents associated with a particular version of the CMMI includes a requirements specification called the Appraisal Requirements for CMMI, which specifies three levels of formality for appraisals: Class A, B, and C. Formal SCAMPIs are conducted by SEI-authorized Lead Appraisers who use the SCAMPI A Method Definition Document to conduct the appraisals.
Class A, the most formal, is required to achieve a rating to Level 5 ), using the Staged Representation, for public record or for response to U.S. Department of Defense requirements.
