Scoring Specific and Generic Practices

The way Specific and Generic Practices are scored is defined in TAMAR.

Using all the information that has been gathered, including interviews with corroborated documentary or other evidence, the Specific and Generic Practices are scored using the following criteria.

  • Fully Achieved – (F) – Greater than 85%
    • The associated interview findings and reviews of supporting artefacts indicate the Specific or Generic Practice is implemented and institutionalised either:
      • as defined by TMMi with no significant weaknesses or
      • a fully adequate alternative practice is implemented
        such that it fully satisfies the requirements of the Specific or Generic Practice.
  • Largely Achieved – (L) – Greater than 50% up to 85%
    • The associated interview findings and reviews of supporting artefacts indicate that:
      • there are some, but no significant weaknesses in the implementation and institutionalisation of the Specific or Generic Practice as defined by TMMi or
      • a largely adequate alternative practice is implementedsuch that it satisfies a large majority of the requirements of the Specific or Generic Practice
  • Partially Achieved – (P) – Greater than 15% up to 50%
    • The associated interview findings and reviews of supporting artefacts indicate that:
      • there are significant weaknesses in the implementation and institutionalisation of the Specific or Generic Practice as defined by TMMi or
      • a limited alternative practice is implemented
  • Not Achieved – (N) – 0% up to 15%
    • The associated interview findings and reviews of supporting artefacts indicate that:
      • there are substantial weaknesses in the implementation and institutionalisation of the Specific or Generic Practice as defined by TMMi and that
      • no adequate alternative practice is implemented
        such that it does not satisfy the requirements of the Specific or Generic Practice.
  • Not Rated – (NR)
    • ‘Not Rated’ is to be used if:
      • The Practice cannot be scored due to insufficient or inconsistent evidence or
      • The assessors cannot reach consensus on the rating
    • Note: More information may be required to make an assessment of the Specific Practice or Generic Practice and assessment methods must define a process by which issues are resolved where Practices are given a rating of NR to ensure that Process Area and Maturity Level ratings can be determined.
  • Not Applicable – NA
    • This cannot be used in scoring Specific or Generic Practices

It is up to the assessment team to decide which of the five ratings (F, L, P, N or NR) fit the Practice. If it is felt that there is a significant weakness then the Practice is unlikely to score an F or an L.

Remember, if an interview statement can not be verified through other evidence then it must score ‘N’ in a formal assessment.
