CHAPTER 20The AI revolution in software development
It’s 8 a.m., and the third floor of a bank in London comes alive as the day crew—three engineers shaking off the rain—steps into their office. Screens glow with activity. Logs scroll. The soft hum of their computers lingers in the air.
The AI agent teams—nearly a hundred of them—have just finished their shift, having spent the night refining a new cross-border payment system, testing failure paths, and shipping updates at a pace no human team could match.
The humans drop their bags and begin the daily ritual: a sprint review that now happens every morning, not every two weeks. Waiting for them is a neatly organized stream of AI-generated pull requests, test evidence, and risk flags—more progress in 12 hours than a traditional team might make in a month.
The job of the engineers isn’t to code so much as to steer, apply judgment to, and adjust priorities for the AI agents working for them. The engineers’ focus is much more on structuring agent tasks into precisely defined workflows, ensuring their activities are predictable and high quality (e.g., predefining the sequence of agent activities), and structuring templates for agentic output.
Sound like sci-fi? It’s not.
An agent factory for a large G-SIB1 bank has successfully done this, including the new daily sprint cadence with humans. The results are staggering: 10x the speed at half the cost. That’s a revolution!
