The Sovereign Engineer by Russ Miles
AI is an amplifier. It magnifies whatever engineering discipline — or lack of it — already exists, which means the bottleneck was never AI's capability; it is the collaboration space you design around it. This book is a six-level progression from early AI panic to sovereign engineering: the discipline of designing the environment in which human and artificial intelligence produce work worth keeping. It moves past prompting into the practices that compound — verification, habitat engineering, specification-first development, and the platform discipline that scales the practice across teams. The habitat is yours to design. Let's build it well.

10 Steps to Flow: A Practical Novel for Software Delivery Leaders by Plamen Balkanski
David leaned forward, intrigued. "An inventor of better systems? You always say stuff like that Alex! What do you mean?""I have a theory. The reason most organisations fall back," Alex explained, "is because they fall into the trap of believing that they have 'arrived'. They find a process that works, a method they like, a 'way of working', and then they try to preserve it, to freeze it in time. They codify it, they build policies around it, and they turn it into a dogma. This approach may have worked in the past but in today’s fact paced world, a process which can’t be continuously improved, soon becomes an obstacle.”

Harness Engineering by Ian Johnson
This book teaches harness engineering as a discipline. Not magic prompts. Not vendor tricks. Engineering practice applied to a new substrate.

Micro Habits for better Teamwork by Dr. Denniz Dönmez & Dr. Rafael Huber
Good teamwork is a skill. Like any skill, it can be learned — through small, deliberate practice, repeated often enough to become second nature.Micro Habits for Better Teamwork is the practical guide teams have been missing: grounded in psychology, built for everyday use, and designed to make a real difference from day one.
