Problem

Heiwa wanted all employees to be able to use generative AI safely for daily work such as minutes, approval documents, and code.

Approach

Heiwa built the assistant in about one month on Bedrock Claude Chat, an open-source project that runs on Amazon Bedrock, and tied it to its existing SAML sign-in. A three-month pilot with 60-70 employees from several departments followed. The tool was then opened to more than 500 employees.

Results

8割近くshare of pilot survey respondents who said generative AI was effective for their work (nearly 80%), per AWS Japan's blogVendor case study[1]

500名を超えるnumber of employees the assistant was released to after the pilot (more than 500), per AWS Japan's blogVendor case study[1]

Takeaway

Heiwa started from an open-source base and a small cross-department pilot before widening access.
