## When to use it

Use when a vendor notifies a model change, the client proposes a new use, or the contract changes subprocessors or location. It points back to the inventory, the risk table and the test record. It does not replace them.

## Used for these tasks

- [Draft a privacy-impact or algorithmic-impact assessment for the system](https://ailawframework.com/obligations/ai-decision-systems/draft-a-privacy-impact-or-algorithmic-impact-assessment-for-the-system.md)
- [Build a legal-risk table for a client's AI system](https://ailawframework.com/obligations/ai-decision-systems/build-a-legal-risk-table-for-a-client-s-ai-system.md)

## How AI may be used

AI may set out what the vendor's notice says has changed, quoted from that notice. The principal decides which earlier conclusions are no longer reliable.

**AI may:**

- Quote the vendor's notice into the change row, with the date of the notice
- List the earlier inventory, risk table and test record on the file

**AI must not:**

- Must not decide that an earlier approval still stands
- Must not treat a vendor's statement that the change is minor as a legal conclusion
- Must not update the privacy policy

**The lawyer checks:**

- The change is taken from the notice or the new contract, not from a newsletter summary
- The principal has said which of APP 1.7, APP 6, APP 8 and the earlier test must be looked at again
- Any privacy-policy wording is changed only by the principal, and only if the classification still requires it
