What is IEEE UL 2933?
IEEE UL 2933 is a sociotechnical data governance architecture standard for clinical AI. It defines the TIPPSS framework and a five-level governance maturity model that D&O carriers, bond counsel, and rating agencies use to assess institutional AI governance posture.
IEEE UL 2933 is a sociotechnical data governance architecture standard for healthcare AI. It defines the governance architecture that health systems must implement to make AI deployment in clinical environments defensible, auditable, and trustworthy.
The standard defines the TIPPSS framework (Trust, Identity, Privacy, Protection, Safety, Security) and a five-level maturity model that describes the governance journey from ad-hoc controls to adaptive institutional leadership. Level 3 is the minimum fundable, defensible, and insurable threshold.
Sherri Douville, CEO of Medigram, serves as Co-Chair of the Trust and Identity Subgroup within IEEE UL 2933. IEEE UL 2933 is cited in CHIME AI Principles and incorporated into HSCC model contract language. It is a governance architecture standard.
Level 3 is the minimum fundable,
defensible, and insurable threshold.
The IEEE UL 2933 Maturity Model describes five levels of governance maturity. D&O carriers require Level 3 evidence at renewal. Bond counsel requires Level 3 for defensible AI traceability answers in covenant review. Rating agencies treat below-Level-3 governance as a credit risk factor.
Darwin by Medigram is built to IEEE UL 2933 and its TIPPSS architecture. Darwin assesses AI vendors against all six TIPPSS dimensions, creates sealed governance records at the moment of every governed decision, and aligns to the maturity model so organizations know which level their governance posture achieves.
Darwin achieved RAISE 4.0 Strong on Praxen, the highest Praxen behavioral verification score recorded to date, confirming that it acts the way its IEEE UL 2933 governance documentation claims it acts.
