Your teams have the tools. The models. The budget. But when leadership asks "What measurably changed because of any of this?" — nobody has a clean answer. Intent-Driven Engineering is the first complete standard for solving that problem. It replaces informal prompt workflows with compiled, versioned, governed production systems that engineering organizations can own, measure, and improve continuously — the same way they manage every other critical system in their stack. This book is the complete implementation guide. Forty chapters that take you from the root causes of AI initiative failure all the way through to a fully operational enterprise AI engineering practice. Every concept is grounded in real deployments. Every example is runnable. Every metric is measured, not projected. Feature cycle time down 57%. Pull request review time down 83%. Incident mean time to resolution down 38%. These outcomes came from the same organizations that were struggling six months earlier — not because they changed their models or increased their budgets, but because they changed their discipline. The book is structured like the standard it describes. Part I names the problem without softening it. Part II establishes the conceptual shift from prompts to intent. Parts III through VII build the complete technical specification — the intent file, the compiler, the agentic platform, the measurement model, and the feedback loop. Parts VIII through X validate the standard against anti-patterns, real deployments, and the broader professional context. By Chapter 16 you will have written, compiled, and deployed your first production-grade intent file. By Chapter 40 you will have the complete architecture for an enterprise AI engineering practice that produces measurable outcomes and improves without manual intervention. This is not a book about what AI can do. It is a book about how engineering organizations use what AI can do to produce outcomes that matter. That distinction is the one that separates the AI initiatives that survive executive scrutiny from the ones that get quietly wound down. The field has been waiting for a standard.
