Start with the evidence
Separate missing sources, unclear purposes and approval questions. Include the reference and the person who can supply the answer instead of placing every unresolved record in a generic review bucket.
Work through the example
Three records need three different actions: retrieve a receipt, explain a project link and confirm an approval. Assigning all three to the same person may delay the one answer they cannot provide.
Make the next step clear
Review aging items at an agreed interval and record the resolution beside the question. Keep a source of truth for status so a chat reply does not leave the queue permanently out of date.
Keep the source context
These guides concern the evidence behind a business record. A receipt, a reimbursement request and a bank movement may describe related parts of one event, but they are not interchangeable documents. Keep each source and its role visible.
