    Incorporate 11.2.2 SupportLevel (enumeration) (p52) in a coherent way into merged SACM metamodel

  • Disposition: Closed; No Change — SACM 2.0
  • Disposition Summary:

    Addressed by harmonization to create SACM 2.0.

    SupportLevel enumeration has been removed. In redefining SACM 2 it was recognized that there was no established approach (accepted by even a small group of industry) as to how to represent confidence and uncertainty on SACM artefact and argumentation elements. Consequently, SACM 2 deliberately pulled back from standardising in these areas. Confidence information could be added to any model element (if required) using TaggedValue (which could use a community consensus vocabulary established using the Terminology package). In addition, SACM 2 recognises that substantiative assertions about artefacts / evidence should be documented as Claims. It also recognizes the potential (which may be particularly relevant when discussing confidence) to attach metaclaims to any Assertion (see metaClaim association on Assertion).
