Before redesigning a review process, distinguish a missing source from a poor draft and a changed requirement.
Sort the causes of revision in a fictional room-preparation note before deciding which part of the workflow needs attention.

Ask whether the necessary information existed
Imagine a fictional draft describing how to prepare a shared room for a workshop. The reviewer returns it because the required seating arrangement is missing. Before changing the drafting instruction, ask whether that arrangement was available in the source material. If nobody had decided it, the draft could not legitimately resolve the question by inventing a convenient answer.
Record the missing input and the decision needed to supply it. A source gap calls for clarification from the appropriate owner; it is not the same problem as wording that is hard to read. In this example, the useful next step is to preserve the unanswered seating question and keep the preparation note pending on that point. The rest of the note can still be reviewed within its known limits.
Separate a draft error from a changed requirement
Now suppose the approved arrangement was present in the source, but the draft described a different layout. That is a mismatch between the output and the available instruction. The reviewer can point to the relevant source and explain the correction. Keeping this case separate from a missing input makes the proposed remedy more specific: the problem concerns how the draft represented information that already existed.
A third case is different again. The draft may have accurately reflected the arrangement at the time it was written, and the workshop plan may have changed afterwards. The note needs revision, but the revision is not evidence that the earlier draft misread its source. Preserve the sequence of the change so that a later discussion does not treat every returned item as the same kind of failure.
Choose an improvement that addresses the cause
The categories help frame a next decision. A recurring source gap may suggest a clearer preparation checklist. A repeated mismatch may justify revisiting the drafting and review instructions. A changing requirement may call for a better way to identify which version a note follows. Each proposal addresses a different cause and should be examined against a corresponding fictional example.
Leave room for uncertainty when the reason for a revision is not clear. Do not force an ambiguous case into a category merely to produce a tidy count. Record the evidence needed to distinguish the possibilities and keep the underlying work visible. This exercise is a way to investigate rework; it supplies no estimate of lost time and no claim that a particular intervention will improve productivity.
