Difficulty is a poor dividing line between software and people. A machine may handle a technically difficult reconciliation well. A simple-looking exception may still require professional accountability.
A more useful question is: who must answer for the result if it is challenged?
Preparation and decision
Retrieval, extraction, normalization, arithmetic, search, formatting, and draft writing prepare a case for review. Software can often help with these tasks, provided the output remains traceable and easy to correct.
A determination carries a different responsibility. When a regulator, institution, client, or affected person may ask for the reasoning, the qualified reviewer needs to own that reasoning.
This boundary turns the design question into something concrete: what should be in front of the reviewer at the moment of decision?
Sources, gaps, and drafts
Judgment and sign-off
Give the reviewer a strong starting point
- The complete record. Documents, correspondence, applicable policy, and relevant precedent in one place.
- A visible basis. Every important statement links back to its source.
- Honest uncertainty. Missing or conflicting information is shown clearly and routed for attention.
- An editable draft. The reviewer can see the proposed answer, inspect its basis, and change it quickly.
- A captured correction. Reviewer changes become useful examples for quality improvement.
Watch for automation bias
Strong drafts create their own risk. When they are usually right, thorough review can slowly turn into a quick scan. The sign-off remains, while the attention behind it weakens.
Good interfaces make review easy and skipping expensive. They show reasoning in context, highlight departures from normal patterns, and direct more attention to uncertain cases. Independent sampling helps confirm that review remains meaningful.
A reviewer should be able to challenge the work without first reconstructing it.
Clear accountability allows a team to use technology confidently across the preparation layer. The reviewer receives a better file, the record becomes easier to defend, and responsibility remains in the right place.
