OpenAI's case study describes how NTT DATA Group, a large IT services firm, has deployed ChatGPT Enterprise and Codex across roughly 9,000 employees. The stated purpose is to automate routine work and expand the internal use of AI beyond small pilot teams.
The headline claim is that incident analysis — diagnosing and responding to system problems — has been cut to 30 minutes. The source does not state what the previous turnaround was, so the size of the improvement is not independently verifiable; this is a single, vendor-published account with no external data to compare against.
The case study also presents the rollout as an exercise in secure AI adoption at scale, suggesting governance and security controls were central to the deployment. With only one source available, there is no alternative viewpoint or contradicting evidence to weigh, so the figures should be read as the vendor's own reporting.
