Start with one valuable question.
A focused pilot should prove useful work, not just produce an impressive answer.
Choose the work
Select one team and one repeatable task: a policy answer, an operational briefing or a document review. Name the person who will judge whether the output is useful.
Choose the evidence
Identify the source documents, their owners and the permissions the pilot must preserve. Include deliberately inaccessible material to test the boundary.
Agree success before starting
Measure answer correctness, citation quality, task completion and human review effort against a baseline. Record failures as carefully as successes.
Decide whether to expand
Review the evidence with users, IT and security. Expand the scope only after provider connections, operating costs and failure handling are understood.
