Name the daily owner and the definition owner
The person who checks a report each day may not be the person authorized to change its calculation. Record both responsibilities. Also identify the source owner and the person or team responsible for technical changes.
Avoid placing all responsibility under “the business” or “IT.” A handover needs a practical contact route and a fallback when the usual person is unavailable. Any response hours or support commitments should be agreed explicitly, rather than inferred from a dashboard's availability.
Explain what current looks like
Document the expected refresh pattern, the timestamp a reader should inspect, and the source delay that is normal. State whether the last successful result remains visible after a failed update. A view that still loads can contain stale information.
Include the normal row-count range or a simple reconciliation expectation where useful, but do not treat it as a guarantee. A genuine operational change can move the count. The check should initiate a review, not silently delete unexpected records.
Write down the common recovery paths
Describe what to do when a source is missing, a field changes, an identifier stops matching, or an export contains duplicate rows. Separate safe reader actions from changes that require the technical owner.
A recovery note should say how to recognize success and where to record what changed. Avoid instructions that encourage someone to overwrite history or bypass an access rule simply to make the next refresh appear successful.
Keep definition changes traceable
Store metric definitions where the next maintainer can find them. When a calculation changes, record the reason, approval, effective date, and treatment of historical values. Update the interface explanation as well as the implementation.
Keep a small set of worked examples for important calculations. They provide a reusable check when a source or reporting tool changes. Review them when the operational rules evolve so an old test does not preserve an outdated definition.
Package the handover for use
A concise package can contain a system map, source register, metric definitions, refresh instructions, access responsibilities, known limitations, recovery notes, and a change log. Link the documents rather than duplicating definitions in many places.
Finish with a walkthrough in which the receiving person follows the instructions. Ask them to locate the last refresh, explain one metric, and describe how they would report a broken source. Those ordinary tasks reveal whether the handover is usable.
