Could another reviewer reconstruct the decision?

A useful evidence record explains what happened and why it mattered. It should support review without forcing the next person to reconstruct the entire workflow from disconnected logs. A public-sector team is evaluating an assistant that organizes guidance and prepares draft answers for staff review. Published guidance can change, and a confident answer can obscure the source, applicability conditions, or authority behind a statement.

A practical starting point

For this evaluation, reconstruct a closed case using only the retained evidence and list every assumption still required. Connect the original input, generated response, relevant sources, applicable policy, review action, and outcome. Retain version and time information where they affect interpretation. Preserve uncertainty and unsuccessful investigations as part of the record. The immediate concern is whether an answer derived from superseded guidance is presented as the current basis for a consequential decision. The review should make that possibility testable, rather than relying on the apparent fluency or completeness of the output.

Examine the boundary

Include a retired guidance document alongside its replacement and ask a question whose answer depends on the revision. Ask a reviewer who did not participate in the original workflow to follow the evidence trail. Identify which claims can be checked, which depend on an inaccessible source, and which lack an accountable decision. Use those gaps to improve the record's structure. Bring the service owner and the authority responsible for the underlying guidance into the review when the finding affects an operational or institutional decision. Their role is to connect the evidence with the authority needed to act on it.

Keep the evidence connected

Use a response record showing the applicable source version, cited passage, unresolved question, and reviewing staff role. Record the observation, source identifiers, relevant excerpts, policy version, decision authority, reasoning, and resulting action. A later reviewer should be able to see the original question, the observations that mattered, and the point at which the team moved from investigation to a decision. Preserve contradictions and unresolved questions alongside the outcome.

From evaluation to use

Use the assistant to support preparation and review. Establish how staff identify authoritative guidance and handle cases that cannot be resolved from the available record. A large log is not necessarily an adequate evidence package. Completeness depends on whether the record supports the specific decision and its stated conditions. The practical next step is a bounded review with an identified owner, a stated question, and an evidence package that supports the decision.
