Create another record when the owner, purpose or risk is materially different. ### Use observable wording Write facts, rules and expected results that another person can inspect. Replace words such as “quick”, “complete” or “automatic” with a time, population, event or named responsibility. ### Record uncertainty Mark missing evidence and unresolved decisions openly.

Destination field Describe destination field for the exact scope being reviewed. Include the source of the information, the person responsible for keeping it current and the evidence that would show the entry is wrong or incomplete. ### 3. Transformation rule Describe transformation rule for the exact scope being reviewed.

The example is intentionally modest: it shows the quality of a useful entry without suggesting a universal answer. ### Source field The team wants one agreed record and owner for website enquiries received during working hours. Success means each valid enquiry has a source, owner and dated next action. ### Destination field Amina owns the working definition; Sam covers absence. The office team can edit the record, while managers can review exceptions and results. ### Transformation rule The team tests five ordinary examples plus a duplicate, an opt-out, missing information and an unassigned record. Every mismatch is logged for correction. ### Test and exception result A person reviews the result after two weeks. Activation or wider use proceeds only if the sample reconciles and staff can handle exceptions without a private workaround. ## Treat the template as a decision record, not a certificate A completed worksheet helps people inspect their reasoning. It does not itself establish compliance, product availability or a successful implementation. ### Check the evidence Ask whether every important statement has an identifiable source and whether that source covers the current scope. Recheck vendor capability and account configuration separately. ### Test the handover Give the record to someone who did not write it. If they cannot explain the owner, rule, exception and next action, revise the wording before relying on it. ### Set a review trigger Review after a failed test, material process change, supplier change, new channel, altered responsibility or evidence that staff are bypassing the agreed method. ## Frequently asked questions ### Can we use this field-mapping worksheet without changing it?
