  1. SAIF and Sound: Fast Track to Standard Development Leveraging rigorous process to accelerate standard development and approval through predictable and repeatable processes (Draft Proposal)

  2. 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

  3. 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 Opportunity

  4. HDF • HL7 Development Framework • DAM • Domain Analysis Model • DIM • Design Information Model • D-MIM and R-MIM are equivalent for message designs • ITS • Implementation Technology Specification • GOM • HL7 Governance and Operations Manual • PLCPD • Project Life Cycle for Product Development • SAIF • Services Aware Interoperability Framework • CIM • Computation-Independent Model • SAIFConceptual Model • PIM • Platform-Independent Model • PSM • Platform-Specific Model • SOA • Service Oriented Architecture Glossary

  5. An example of Model Driven Architecture: Software Development Model/Artifact Role Model Driven Development www.jot.fm/issues/issue_2006_03/column4/ OMG – Object Management Group OMG Model Driven Architecture

  10. 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 SAIF Adoption
