Start with the decision, then inventory the reports
A smaller reporting estate is useful only when it preserves the decisions that matter. List recurring outputs, their owners, audiences, source systems, refresh cadence, and the action each report supports. A dashboard, an exported deck, and a scheduled spreadsheet are different units; choose a counting rule and keep it stable.
Agree the baseline before retiring anything
Record the observation window and the number of active outputs under that counting rule. Distinguish permanently retired reports from reports merged, renamed, or moved to another platform. Measure analyst preparation time separately from report count.
| Measure | Definition |
|---|---|
| Active recurring outputs | Outputs delivered and used during the same defined observation window. |
| Net retirement rate | (Baseline count minus retained count) divided by baseline count, using the same counting rule. |
| Preparation effort | Observed analyst hours on preparation, reconciliation, and correction. |
| Adoption | Named decision owners using the replacement output in the agreed review cadence. |
| Control quality | Defined metric ownership, reconciliation checks, and a route for reporting defects. |
Reconcile the metric logic
Sales and Finance need an agreed treatment of revenue, cost, rebates, currency, and timing before a shared report can become trusted. Keep a definition register with an owner, source hierarchy, calculation order, and test examples. A consolidated semantic model should make these rules inspectable.
Pilot the replacement in a real review
Run the proposed output alongside the existing review for an agreed period. Track disagreements, missing decisions, manual workarounds, and access problems. Retire an output only when its owner confirms that the replacement supports the required decision and the fallback is clear.
Keep the controls after the migration
Give each shared metric and reporting model a named owner. Review usage and defects regularly. New report requests should identify a decision and audience, explain why the existing view is insufficient, and have an agreed maintenance owner.
Report the result with its limits
Publish the baseline, counting rule, period, retained outputs, preparation effort, and adoption evidence together. A reduction percentage by itself does not establish time saved, stronger decisions, or a financial return. This article describes a method; it does not assert a verified client result.
