Claims
- Endava uses Codex across requirements analysis, design, specifications, development, and operations—not just as a coding tool.
- Senior architects' judgment encoded into Codex enables junior developers to produce senior-quality outputs in real time.
- Endava compressed a requirements process that typically took weeks into two one-hour meetings by feeding a meeting transcript to Codex.
- Endava now describes itself as an 'agentic organization' where senior expertise is codified into agents that work alongside teams across the full client engagement lifecycle.
Key quotes
We went from producing a lot of the code ourselves to now overseeing the work that Codex can produce. The quality of output has just gone up exponentially.
What Codex has really helped us do is have small teams of people deliver massive value in a very condensed timeframe.
Codex magnifies every skill I have, and everybody who learns how to use it gets every skill they have magnified.
