Professional services: internal knowledge assistant pilot

Situation

Junior staff kept asking seniors the same questions, and answers lived across PDFs, wikis, and chat history. The organisation needed grounded help without turning internal search into guesswork.

What we focused on

• Corpus design: Authoritative sources only; explicit “not found” behaviour.
• Evaluation set: Regression tests on answers before each model or prompt change.
• Access control: Sensitive practice areas segmented, no cross-leakage.

Outcome

Faster onboarding and fewer interruptions, without pretending legal advice could be automated.
