Firms Know Who Activated AI Tools — Almost None Know Who Changed How They Work

BARBRI's August research on AI adoption at scale surfaced a distinction now familiar to legal operations professionals but rarely articulated by firm leadership: technology spend is up 9.7% and KM investment is up 37.2% since 2021, yet firms that have deployed AI broadly can identify which lawyers activated tools — and almost none can identify which lawyers actually changed the way they work. The billable hour, BARBRI argues, is not just a pricing structure but the primary measurement unit for lawyer performance, and it makes behavioral change structurally invisible: a lawyer who uses AI to produce a first draft in 20 minutes instead of four hours has no incentive to record the time savings if billable hour targets remain unchanged. The report concludes that training alone cannot fix this — it requires changes to how firms measure and reward lawyer productivity, a question that touches compensation, performance review, and partnership economics simultaneously.
