Endava uses Codex to turn senior judgment into agents
Endava says it has adopted Codex across requirements, design, development, and operations, calling itself an “agentic organization.” The company says the tool helps junior staff work with senior-level guidance and has shortened some workflow steps from weeks to days.
Endava, the global software contracting firm, says it has become an “agentic organization” after early adoption of Codex. The company, which works with banks, insurers, retailers, and media firms, says the tool now helps its teams across the full client engagement lifecycle, from intake to delivery.
Joe Dunleavy, Endava’s regional CTO for Europe, said the change has shifted the company from producing much of its code itself to overseeing work Codex can generate. “The quality of output has just gone up exponentially,” he said. Dunleavy added that small teams can now “deliver massive value in a very condensed timeframe.”

This is about a software company using an AI coding tool to help with more than just writing code. Codex is a software agent that can help with tasks like requirements, design, and operations, which means it can act like a digital assistant for parts of the development process. For non-experts, the key idea is that companies are starting to use AI to spread senior workers’ knowledge across more people and more tasks.

If you run self-hosted agents, start by applying them to non-coding workflows first, just as Endava suggests: requirements notes, design docs, meeting transcripts, or internal support summaries. Capture your best senior operator’s decisions as prompts, templates, or policy files, so the agent can apply that judgment consistently across the team.
Also, test whether your agent can support live client or stakeholder sessions by turning notes into specs or diagrams in real time. That forces you to measure the agent on usefulness and clarity, not just code generation quality.
Endava describes an agentic organization as one where senior expertise is codified into agents that work alongside teams. In practice, the company says that means using Codex not just for coding, but for requirements analysis, design, specifications, development, and operations.
Mike Krolnik, Endava’s Global SVP of Agentic Architecture, said the tool changes how senior and junior engineers collaborate. Senior architects can explain what they want, and Codex can present that knowledge in a form junior staff can use while working on assignments that would normally go to more experienced engineers.
Krolnik said junior developers can ask Codex questions as they work, making it a learning tool as well as a production tool. He said the goal is to take senior experience, codify it, and have Codex help teach better software architecture and development practices to the team.
That model also changes how Endava handles delivery stages. The company says analysis, design, and build are no longer treated as separate handoffs between specialists. Instead, Codex packages those steps together as a single tool, which Krolnik said shortens work that used to take days or weeks.
Endava pointed to a legal-team project as one example. The company said its legal group needed engineering help to review thousands of pages of contracts against specific criteria. Rather than spending weeks in back-and-forth meetings, Krolnik’s team recorded a two-hour deep-dive meeting, fed the transcript to Codex, and used it to generate a working requirements specification.
According to Endava, that process cut what could have been one or two weeks of revision down to two one-hour meetings. The company said the result was a usable specification that engineering could move forward with more quickly.
Endava also said the tool is helping during client sessions. Teams now produce design documents, diagrams, and specifications live in meetings to show ideas and speed up discussion. Krolnik said Codex can draw proposed software architecture diagrams on request, which helps clients understand the approach and reduces the amount of back-and-forth.
Endava’s leadership said the biggest value comes from capturing senior judgment and using Codex to spread it across teams. Dunleavy said teams should get past the planning stage and try the tool in practice. The company’s recommendation to teams starting out is to begin with a non-coding workflow such as requirements analysis, design documentation, or client communication.
