NTT DATA Group needed to raise productivity across technical and nontechnical roles, automate repetitive analysis work, and make agentic AI safe enough for broad enterprise use rather than isolated engineering experiments.
Reported impact
NTT DATA Group reduced a complex incident analysis from three days to 30 minutes, expanded Codex to about 9,000 active users, improved weekly active usage after enablement, and lowered the barrier for nontechnical employees to automate their own work safely.
NTT DATA Group first deployed ChatGPT Enterprise companywide and wrapped it in an OpenAI Center of Excellence that handles licensing, validation, events, knowledge resources, monitoring, and internal systems so employees can develop practical AI habits. On top of that base, the company expanded Codex to roughly 9,000 employees across technical and nontechnical roles. Codex now investigates incident patterns, scripts routine work, analyzes Excel and file collections, and even automates multi-file operational tasks that previously required specialist help. One early proof point was a critical incident analysis that moved from five engineers over three days to a 30-minute Codex run. Security and governance guidance define usable data, connected systems, sandbox modes, automation boundaries, and mandatory human review so the same agentic workflows can be generalized internally under the company's Client Zero model and later adapted for customers.
Employees start with ChatGPT Enterprise for research and drafting, then hand defined tasks to Codex for investigation, file handling, data analysis, and automation. The Center of Excellence enforces data-use and sandbox rules, and validated automations such as Playwright-based routines are packaged and shared as reusable skills across departments.
"Building on that foundation, the company has expanded Codex to approximately 9,000 employees."
"Codex completed an incident analysis in 30 minutes that had previously taken five engineers 3 days"
"Creating a secure and well governed environment is essential for employees to use Codex with confidence."
"Through our Client Zero approach, we actively promote the use of AI within our own organization."
