Project Scope Statement (PSS)

The UTG PSS was approved by all co-sponsors at the San Antonio WGM the week of January 16, 2017. It was forwarded to FTSD for approval on January 20, 2017. The document may be directly downloaded from UTG PSS V1

Project Overview

HL7 currently maintains multiple terminologies - v2, v3, CDA value sets and FHIR, but does not currently have a uniform vocabulary governance process or strategy across all the HL7 product lines.  Ongoing maintenance of these terminologies is resource intensive and is also quite opaque to much of the community.  As FHIR and associated implementation guides become more popular and as HL7 continues to grow, this is becoming a greater problem.  There is a need to maintain the terminologies that support all of HL7’s products (v2, v3, FHIR, CDA, etc.) in a way that is responsive and improves quality while reducing the resources that both HL7 and its volunteers must put into the process.  As well, there’s a need for the process to align with the community’s expectations for a more modern, continuous peer-feedback related process.

The UTG project will replace existing vocabulary maintenance processes (including harmonization) for HL7-maintained terminology across all HL7 project lines.
