NTT DATA cuts incident analysis to 30 minutes using Codex across 9,000 employees
OpenAI Blog·medium signal
OpenAI published a case study on NTT DATA Group deploying ChatGPT Enterprise and Codex to 9,000 employees, reporting incident analysis time cut to 30 minutes. It is one of the more concrete enterprise agentic-coding deployment numbers to surface with a named headcount attached rather than a vague productivity percentage. Worth reading skeptically — it's vendor-published — but the operational detail is more specific than most.
