The Implementation Maturity Framework comprises five distinct maturity levels, each representing a stage of progression in SNOMED CT implementation. While these levels are specifically described and tailored for each stakeholder group - Members (National Release Centers), User Organizations, and Vendors; SNOMED International has also defined a set of general maturity levels that apply universally across all stakeholders. A general overview of these common maturity levels is as follows.
