McKinsey Replaces Junior Analyst Drudgery with Generative AI

The shift centers on Lilli, an internal engine that draws from the firm’s vast repository of proprietary research and past client engagements. Since its launch in July 2023, the system has processed over 500,000 prompts monthly, effectively handling tasks previously relegated to junior analysts. Kate Smaje, McKinsey’s global leader for technology and AI, suggests that the need for armies of analysts to build PowerPoint decks is waning, as the technology now generates outlines and charts in mere minutes.

This automation has yielded significant efficiency, with McKinsey reporting 1.5 million hours of human work saved over the past year. By offloading the mechanical production of proposals and data synthesis to AI, the firm claims it is freeing consultants to focus on high-level strategy and client-facing judgment. CEO Bob Sternfels maintains that the technology serves as a collaborator rather than a replacement, emphasizing that human creativity and orthogonal thinking remain the core value proposition of the business. Despite this AI-driven surge in productivity, the firm has seen its headcount contract to approximately 40,000 employees globally, down from over 45,000 at the end of 2023.
