Accenture deploys Microsoft 365 Copilot to 743k employees, setting a corporate enterprise deployment scale record

AIMPACT message, April 28 (UTC+8): Accenture has deployed Microsoft 365 Copilot to about 743k employees—currently the largest known enterprise-level Copilot deployment. According to a 2025 survey of 200k users, 97% of employees said that after using Copilot, the speed at which they complete routine tasks increased by 15 times, and 53% reported a significant improvement in productivity and efficiency. Accenture CIO Tony Leraris described Copilot as a “personal digital colleague.”

The rollout began after Microsoft released Copilot in August 2023, gradually expanding from pilot programs involving hundreds of executives to 20k people, and ultimately covering all employees. The company optimized its data strategy, governance, and access controls, and adopted a customized change-management plan. Data shows that among users of about 200k licenses, the monthly active usage rate reached 89%, and 84% of users said they would miss Copilot a lot if they lost it. In the marketing department, Copilot helps address information consistency issues and simplifies collaboration. (Source: InFoQ)
