Codex can build the tool. Your people define “good.”
Start with a recurring handoff. Build with the people who do the work, and test the result.
What changed
OpenAI’s August 25 account describes an engineer using Codex with workflow tools to automate repetitive engineering and evaluation tasks. The example emphasizes retained context, review boundaries, decisions and lessons. Codex is an AI coding agent; its ability to help build software does not establish that the resulting business process is useful.
Where businesses stumble
A fast prototype can reproduce an awkward spreadsheet, hide an exception or depend on one enthusiastic employee. Staff may work around a tool if its designer never observed the real handoff.
The CBA response
C: map one recurring request and define the finished outcome with its users. B: curate requirements, authoritative records and acceptance examples. A: develop a small internal tool, test it with staff and review changes before release. Give the tool a maintenance owner and a route for reporting problems.
One practical takeaway
Choose one bottleneck and measure its baseline cycle time and rework. Test the prototype against real normal and exception cases; accept it only when the end-to-end work improves.
Right-sized for midsize business
A midsize firm needs coordination between operations and IT, access appropriate to the task, and time for maintenance. A bounded pilot keeps the cost and integration burden visible.
