What early readers are saying

Quotes translated from the Spanish edition.

In an industry that rewards doing, Edu has spent years practicing and teaching the equally difficult art of not doing: not building what doesn't add value, not accumulating what isn't needed. This book is, among other things, a manual for that intelligent restraint.
— Andoni Eguíluz Morán, Dean of the School of Engineering, University of Deusto
I had read many books and articles on Lean and Agile, but I had never seen such a radical and deep application of their principles.
— Borja Cadenato, Director of Product
A book written from the wisdom of knowledge and experience that helps build awareness of the Basal Cost of software, a concept coined by the author himself. It is said that what has no name does not exist. And if it does not exist, nothing will be done to manage it.
— Raquel M. Carmena, Software Engineer
This book captures something I've been seeing for years in what Edu writes: a constant pursuit of simplifying without falling into oversimplification. The result is a very solid guide, grounded in real experience with Lean, XP, and the original concept of Basal Cost, for anyone who wants to build software with more impact and less noise.
— Julio César Pérez Arqués, Engineering Manager
An essential book for developers and teams that want to rethink the way they relate to code. Edu has written a book that shows, with real cases, that applying Lean, XP, and Basal Cost is a win-win.
— Javier Vela, Software and Platform Engineer
