Harness Engineering in Practice: From Requirements to Implementation

AI assistants are getting more capable. The question is how we build effective workflows around them.

At DevDay London, Lucy Joyce, Ash Shakrani and Arun Kurian will explore harness engineering through the lens of a payment integration.

From requirements and design through to implementation, they’ll demonstrate why context alone isn’t enough for successful AI-assisted development. Drawing on real-world experience, they’ll show how engineering harnesses, reusable context, standards, and validation workflows help teams move beyond experimentation and build reliable, scalable AI-assisted development practices.

This session will unpack:

🎯 Why “more context” isn’t the answer on its own
🎯 What engineering harnesses are and how they create reliable feedback loops
🎯 How standards, workflows, and validation reduce AI-generated rework and technical debt
🎯 Practical techniques teams can adopt immediately to improve AI outcomes
