What is in there ?
Simplicity
Everything in this book is simple, appliable and actionable. No philosophycal advices, no agilisms, no tiresome coding or infra good practices. It is a concise and straight field guide, similar to the ones we used to have to fix computers, televisions and machinery.
Scale
Everything is battle tested, based on more than 25 years of experience and 10 years advising tech companies.
Its goal is to get anyone comfortable and prepared to lead in any scenario. This is not a regular Engineering Management book. It is meant to be accessible.
Engineering
This is a book about tech leadership - leading engineering and product organizations. No cheap philosophy or snake oil. You get what you see - it helps you start managing a tech team, define a set of expectations to fulfill and how to grow doing it.
