Start with a defined collection, such as internal procedures or approved technical guidance. Appoint a source owner so obsolete documents can be replaced and competing versions resolved.
Test questions the material can answer and questions it cannot. Source references help a person inspect the response; they do not remove the need to review it.
Illustrative task: A team member asks which internal checklist applies to a project stage. The assistant identifies the relevant guidance and reference. The team member checks that it applies to their situation.
