The Standard CMMI Appraisal Method for Process Improvement (SCAMPI) is the official Software Engineering Institute (SEI) method to provide benchmark-quality ratings relative to Capability Maturity Model Integration (CMMI) 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, the most formal, is required to achieve a rating (Level 1 (lowest) to Level 5 (highest)), using the Staged Representation, for public record or for response to U.S. Department of Defense requirements.
