NTT DATA Cuts Incident Analysis to 30 Minutes with OpenAI Codex, Deploys AI to 9,000 Employees

Japanese IT services giant NTT DATA Group has shared new details on its enterprise-wide AI deployment, revealing that 9,000 employees are now using ChatGPT Enterprise and OpenAI Codex to automate workflows with measurable results.

The most striking outcome is in incident analysis. NTT DATA reported that Codex's code generation and analysis capabilities have reduced system incident analysis and troubleshooting from several hours to roughly 30 minutes. For a company managing massive IT infrastructure, this represents a step-change in operational response speed and team productivity.

NTT DATA's deployment goes beyond simple tool rollout. The company established an internal AI governance framework to ensure security and compliance while maximizing the benefits of AI automation. This structured approach provides a blueprint for other large organizations navigating the complexities of enterprise AI adoption.

Codex plays a central role in the deployment. NTT DATA engineering teams use it to auto-generate code, write test cases, analyze log files, and accelerate internal tool development, freeing developers to focus on higher-value tasks.

With over 150,000 employees globally, NTT DATA is one of Japan's largest IT services providers. Its aggressive embrace of AI tools signals that traditional IT services giants are moving quickly to integrate AI into their operations. The case also demonstrates the viability of OpenAI's enterprise products in large, complex organizations and may accelerate AI adoption decisions across Japan and the broader Asia-Pacific region.
