There are many books and manifestos or even books about those manifestos :-) the aim of which is to teach you how to be more efficient. They provide you with diverse recipes and tools to be more efficient as a person, as a developer but also as organizations. All those writing also have another important thing in common; they all say that in order to be more efficient you constantly need to focus on delivering value or even steadily adding value. In this presentation I try to define what exactly value is and the kind of things you could put in place (and things to avoid!) to bring it down to your code or even within your tests.

- 26. “Specifications themselves are incredibly difficult to get right. [...] Specifications are not written in computer language. They’re written in a horrible, horrible, language to describe something explicitly, and that would be… English! Or any other language that humans use to communicate. If you can write poetry and have two people feel different things when they read your poetry then it’s obviously not the right language to write specifications that are supposed to produce always the same output!” Theo Schlossnagle from “Responsibly maximizing craftsmanship in software engineering”
