The Standard CMMI Appraisal Method for Process Improvement (SCAMPI) is the official method to provide benchmark-quality ratings relative to 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.

• SCAMPI Class - A Appraisal
  • A SCAMPI A appraisal is typically conducted when an organization has implemented a number of significant process improvements and needs to formally benchmark its processes relative to the CMMI. A SCAMPI A is the only appraisal method that provides CMMI Maturity Level or Capability Level ratings.
• SCAMPI Class - B Appraisal
  • A SCAMPI B is called for when an organization needs to assess its progress towards a target CMMI Maturity or Capability Level, but at a lower cost than a SCAMPI A. SCAMPI B appraisals provide detailed findings and indicate the likelihood that the evaluated practices would be rated as satisfactorily implemented in a SCAMPI A appraisal. The SCAMPI B essentially serves as a readiness dry-run for the SCAMPI A Appraisal.
• SCAMPI Class - C Appraisal
  • SCAMPI C appraisals are shorter, less formal and more flexible than SCAMPI A and B appraisals and are conducted to address a variety of special needs, from a quick gap analysis to determining an organization's readiness for a SCAMPI B or A.
