A demo is not an evaluation
A successful example can prove that a tool can generate an answer. It does not show whether it performs acceptably across the cases that matter in daily work. An evaluation route makes the difference visible by defining what is tested and how a reviewer judges the result.
Create a small review set
Begin with representative cases: an ordinary request, an incomplete request, an ambiguous request, and a request that should be handed to a human. Pair each with an approved answer shape or a review instruction. This gives the team a practical way to discuss quality without relying on impressions.
Keep the record usable
Store the source used, the task instruction, the output, the review decision, and the reason for any correction. Over time this becomes a learning asset for both the workflow and the people who govern it.
