Problem

JFE Engineering wanted employees to use generative AI for document work while protecting confidential information and personal data.

Approach

The company released its internally developed Pla’cello xChat in September 2023. It used Azure OpenAI and Amazon Bedrock and provided usage guidelines. A dedicated portal and practical workshops helped employees apply the service to daily work.

Results

over 1,600employees regularly using Pla’cello xChat by December 2024, approximately 45% of employees, per JFECompany's own claim[1]

Takeaway

The reported result measured regular use. It did not establish an average productivity gain for each user.
