SAIF and Sound: Fast Track to Standard Development Leveraging rigorous process to accelerate standard development and approval through predictable and repeatable processes (Draft Proposal) 1
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 lets 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 2
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 3

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 10
