1.1 Conformance

The Open Group has developed and maintains conformance criteria, assessment procedures, and a Certification Policy and Program for the O-TTPS as a useful tool for all constituents with an interest in supply chain security. The conformance requirements and assessment procedures are available in the O-TTPS, Part 2: Assessment Procedures for the O-TTPS. Certification provides formal recognition of conformance to the O-TTPS, which allows:

• — Providers and practitioners to make and substantiate clear claims of conformance to the O-TTPS
• — Acquirers to specify and successfully procure from providers who conform to the O-TTPS
