This guide converts requirements into implementation-ready ownership, evidence, and review decisions. It is practical guidance, supporting implementation planning and should be validated against jurisdiction-specific legal, contractual, and policy requirements before implementation. Use the UK IDTA Addendum when you need a UK transfer tool for restricted transfers and the receiving party is relying on the EU SCCs with UK amendments; use a transfer risk assessment to check whether the transfer tool and destination country still provide appropriate safeguards before the transfer goes ahead. This page maps that workflow into a trigger, owner, deadline, required evidence, and review path so legal, privacy, security, and compliance teams can execute consistently. ## How should an IDTA addendum and transfer risk assessment workflow run under the UK GDPR? Use the workflow as UK data-protection triage: first decide whether the transfer needs the UK IDTA Addendum or the standalone IDTA as a safeguard for a restricted transfer, then complete the transfer risk assessment to check whether the safeguard is appropriate in the circumstances and the level of protection is not undermined. - Capture the request, product, role, data flow, jurisdiction, and deadline. - Check the source-linked rule and route exceptions before implementation. - Record the action taken, owner, reviewer, evidence location, and next review date. - Keep a plain-language output that support, product, legal, security, and compliance teams can all understand.

Review the workflow after ICO guidance, adequacy or transfer updates, vendor changes, new profiling, new child-user journeys, incidents, DSAR trends, or complaints. - Track recurring exception categories and update intake questions. - Remove fields that never affect the decision. - Add fields when reviews show missing source evidence or unclear ownership. - Confirm the published page and maintained template show the same source-linked transfer guidance.
