One-standard-per-year Leveraging rigorous process to accelerate standard approval 1

Issues SAEAF 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 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 The HL7 veterans are concerned that introducing new processes and introduction of project management will slow down development of standard 2

Opportunity Leverage HL7 expertise to migrate to SAEAF Evolution rather than revolution Project management Domain analysis V3 Design GOM Stage the SAEAF-required models into iterative milestones Leverage ballot to validate scope and requirements Ballot Conceptual/Domain Analysis Models 3
