Problem

The consulting group launched its own generative AI environment in 2023. Only about 30% of staff used it.

Approach

The group ran a pilot with 50 to 100 employees from August 2024. It then rolled out Google Workspace with Gemini to all employees in November 2024. It collected 50 to 60 use cases, wrote a usage guide and held department briefings. The holding company ran a 15-minute weekly session for staff to share Gemini tips. It reviewed four risks, including confidential data handling and hallucinations.
