1. Research acceleration — the biggest, safest win
Research acceleration is where AI delivers the largest and lowest-risk gain for consultants. A retrieval system pointed at a defined corpus — a data room, a set of transcripts, a body of regulation — can summarise and cross-reference in hours what used to take an analyst days. The safety comes from the boundary: the model retrieves from a known source set, so every summary can be checked against the document it came from.
The failure mode appears the moment the source set is the open web instead of a curated corpus. Open-web retrieval invites confident fabrication, so the discipline is to constrain the model to material the engagement team has actually vetted.
