About this book
Every engineering leader eventually reaches the same moment: the tools have changed, but the system hasn't. Sprint ceremonies, story points, code review queues, QA gates: frameworks built for human teams operating under human constraints. But when AI agents execute code, review pull requests, write tests, and deploy to production, those assumptions don't degrade gracefully. They fail.
REDEFINE is a complete, ground-up rethinking of the Software Development Lifecycle for a world where AI is no longer a tool beside the work, it is part of the work. Drawing on nearly two decades of hands-on engineering operations experience, David Tzemach delivers a precise diagnosis of what is broken in modern delivery, and a practical blueprint for what must replace it.
This is not a book about AI tools. It is a book about software delivery systems under autonomous execution, and the governance, roles, and judgment structures that must evolve alongside them.
What's inside
- A clear account of why Agile's seven fundamental flaws can no longer be patched, and what a rebuilt SDLC looks like from first principles
- A complete guide to agentic AI: how agents work, how to govern them, and how to integrate them into delivery without losing accountability
- Six redesigned SDLC stages, six new engineering roles, a new measurement system, and new ceremonies built for human-agent teams
- The seven mindset shifts every engineer and leader must make before any new method will hold
- Benchmarks, data, and real patterns from the teams already navigating this transition
Who this book is for: Engineering managers, CTOs, architects, senior developers, DevOps engineers, and product leaders who sense the ground shifting and want to act deliberately, before the transition chooses a shape for them.
The future of software delivery will be built by someone. This book exists to make sure it is built intentionally.
