  1. 1. Kittitouch Suteeca Ref. Panit Watcharawitch, PhD (cantab)
  2. 2. Standard CMMI Appraisal Method for Process Improvement (SCAMPI)  SCAMPI is designed to provide benchmark quality ratings relative to Capability Maturity Model® Integration (CMMISM) models. It is applicable to a wide range of appraisal usage modes, including both internal process improvement and external capability determinations. SCAMPI satisfies all of the Appraisal Requirements for CMMI (ARC) requirements for a Class A appraisal method and supports the conduct of ISO/IEC 15504 assessments.  SCAMPI Appraisal System (SAS)  Method Definition Document (MDD)  Appraisal Requirements for CMMI (ARC)  Appraisal Team Member (ATM)  Appraisal Disclosure Statement (ADS) 2
  3. 3. SCAMPI class A, B, C 3
  4. 4. Objective SCAMPI class A  Understand the current implemented process.  Identify process weakness (and strengths) in the organization unit.  Determine degree of satisfaction of CMMI process area goal investigated.  Assign rating ,if request by appraisal sponsor. 4
  5. 5. Rating process attributes  Process attribute rating values: The ordinal rating scale defined below shall be used to express the levels of achievement of the process attributes.  N Not achieved: There is little or no evidence of achievement of the defined attribute in the assessed process.  P Partially achieved: There is some evidence of an approach to, and some achievement of, the defined attribute in the assessed process. Some aspects of achievement of the attribute may be unpredictable. 5
  6. 6. Rating process attributes  L Largely achieved: There is evidence of a systematic approach to, and significant achievement of, the defined attribute in the assessed process. Some weakness related to this attribute may exist in the assessed process.  F Fully achieved: There is evidence of a complete and systematic approach to, and full achievement of, the defined attribute in the assessed process. No significant weaknesses related to this attribute exist in the assessed process. 6
  7. 7. Rating process attributes  The corresponding values shall be:  N Not achieved 0 to 15% achievement  P Partially achieved >15% to 50% achievement  L Largely achieved >50% to 85% achievement  F Fully achieved >85% to 100% achievement. 7

  17. 17. Appraisal keys  Appraisal Considerations  Direct Artifact  Indirect Artifact 17
  18. 18. Example:REQM ML2  15 Key practices  5 Specific Practices  10 Generic Practices  SP 1.1-1 Obtain an Understanding of Requirements  Develop an understanding with the requirements providers on the meaning of the requirements  Appraisal Considerations  Consider existence of requirements at multiple levels (e.g., product and product component requirements.). 18
  19. 19. Example:REQM ML2  Direct Artifact  Allocated Requirements Document  Allocated Requirements Database  Review Report of Requirements  Commitments from affected groups on allocated requirements  Defined criteria for evaluation and acceptance of requirements 19
  20. 20. Example:REQM ML2  Indirect Artifact  Evidence of early (before committing to develop the corresponding software) system requirement allocated to software review (e.g. meeting minutes, reports…)  A list or characterization of requirements providers authorized to provide direction 20
