IssuesIssues

SAEAF 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 fragmentedhttp://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 The HL7 veterans are concerned that introducing new

processes and introduction of project management will slow down development of standard
