Implementation playbook

Turn a source change into controlled action

A practical regulatory-change playbook

Reviewed 1 November 2026Suggested workflow

Start with scope

Suggested implementation workflow. Verify the source, legal status, applicability and actual deadlines before deciding the response.

01

Establish what changed and when

Capture the official source, the exact provision or guidance and the publication date. Separate enactment, commencement, transitional arrangements and consultation deadlines.

Record what remains uncertain rather than assuming an announcement is already an applicable obligation.

Working output: A dated source and legal-status record.

02

Decide who and what is affected

Map the change to the legal entity, activity, jurisdiction, thresholds and exclusions. Obtain suitable advice where applicability requires it.

Identify affected policies, systems, suppliers, contracts, notices, training and records.

Working output: An applicability decision and a practical impact map.

03

Implement with accountable ownership

Assign specific changes, owners and resources. Distinguish verified external deadlines from internal planning targets.

Keep a record of the approved versions, communication, training and testing needed for the change to operate.

Working output: Owned actions with evidence of implementation.

04

Check the change in use

Review a proportionate sample of the new process or records. Confirm whether the change achieved the intended outcome and what remains untested.

Bring unresolved gaps to the accountable owner and define the next monitoring or review trigger.

Working output: A post-implementation review and updated obligations record.
