NTT DATA

NTT DATA employees reported about 30 minutes of weekly savings from its AI chat service

WorkingCompany's own claimOfficial ↗

Problem

Employees needed help with routine writing and information searches. Internal manuals and rules were scattered across separate company sites.

Approach

NTT DATA began early use of its chat service in July 2023 and deployed it company-wide in October. It built the service with open-source applications and Microsoft Azure. Internal knowledge search followed in April 2024, combining retrieval-based generation with its LITRON crawler.

Results

~30 minutesaverage perceived weekly time savings among surveyed chat-service users, per NTT DATACompany's own claim[1]

Takeaway

The time-saving figure reflected employees' perceptions after the chat rollout. It did not establish measured savings from the later knowledge-search service.
