Start with the evidence
Review the unresolved-items list and identify where time was spent finding sources, clarifying ownership or repeating checks. Separate occasional exceptions from recurring patterns.
Work through the example
Four delays came from receipts without project references. Adding a project question to the collection routine addresses that pattern more directly than renaming every folder.
Make the next step clear
Choose one practical change, name its owner and check the result next period. Keep the existing useful parts of the process so improvement does not become another source of review work.
Keep the source context
Keep the review period, source set and unresolved questions explicit. A checklist records work performed; it does not by itself establish that financial statements are complete or compliant. Use the appropriate reviewer for decisions about accounting treatment.
