Frequently asked questions

### What is the difference between AAMI TIR57 and TIR97?

Short answer: AAMI TIR57 vs TIR97 is a discrete deliverable inside the Secure Product Development Framework (SPDF). FDA expects it documented, traceable, and version-controlled inside your QMS. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Do I need both AAMI TIR57 and TIR97 for FDA compliance?

Short answer: Yes — under Section 524B and the February 2026 final guidance, every cyber device requires the artifact in question. Skipping it is the fastest way to an RTA hold.
