Advancing organizational transformation for business innovation
In February 2025, the company launched ChatGPT Enterprise across ten core departments. In areas that require advanced analytical and evaluation techniques, DNP has significantly reduced the time traditionally needed for tasks such as operating experimental equipment for material evaluation, conducting measurements, and performing analyses by leveraging ChatGPT Enterprise. The company established clear benchmarks: each employee should use ChatGPT at least 100 times per week, and over 50% automation rate for task time reduction. > “We drove adoption by making usage visible. The time required to define the data architecture was cut by 90%.

Why it matters
Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 221 sightings filed under Software Development on Agent Sightings (number 66 by interest), and one of 145 involving ChatGPT.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into ChatGPT or any similar agent and adjust the details to your situation.
I want a coding agent to plan first, work on a branch, and show me the diff before anything is merged. The tool in the source case was ChatGPT.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
