SAIF and Sound: Fast Track to Standard Development

Leveraging rigorous process to accelerate standard development and approval through predictable and repeatable processes

(Draft Proposal)

issues

SAIF adoption raises challenges

    • Change management
    • Cultural changes
    • Migration of existing artifacts
  • Voluntary HDF adoption has not worked
    • “Analysis is a waste of time let’s skip it”
  • HL7 V3 change request process is fragmented
    • http://www.hl7.org/memonly/dbtracker_V3/index.cfm
    • Work groups use internal spreadsheet to track change requests
    • The ballot is sometimes the de-facto change submission process
    • The RIM and Vocabulary rely on harmonization:
    • Structured Documents is using wiki to collect CDA R3 change requests
  • Veteran HL7 developers have expressed concern that introducing new processes and introduction of project management will slow down development of standard
Issues
opportunity

Leverage HL7 expertise to migrate to SAIF

    • Evolution rather than revolution
    • Project management
    • Domain analysis
    • V3 Design
    • Well-defined ballot process (GOM)
  • Stage the SAIF models into iterative milestones
    • Leveraging project management
  • Leverage informative and “for comment” ballots to validate scope and requirements
    • Ballot Conceptual/Domain Analysis Models
    • Stage ballots for optimal engagement with HL7 members and stakeholders

SAIF Adoption

saif adoption

We need definitions of SAIF artifacts:

    • Required artifacts and models
      • Relevant view-points only
    • Optional artifacts and models
      • PSM?
      • Are they reusable?
  • We need publication/ballotable examples of SAIF artifacts
  • We need to revise the process definitions in the HDF and reference the new artifacts specified by SAIF
