Il y a beaucoup de livres, de manifestes et même de livres à propos de ces manifestes ;) dont le but est de vous fournir des recettes pour être meilleurs, plus efficaces, plus efficients! Ils vous procurent des méthodes, des pratiques, des outils, pour être meilleurs en tant que personne, en tant que développeur, mais aussi en tant qu’organisation. Ils ont également un autre point commun, c’est qu’ils insistent sur l’importance de délivrer de la valeur! Dans cette présentation, j'entreprends de définir de manière concrète ce qu'est la valeur. Je livre une technique simple et efficace à mettre en place ainsi que celles à éviter, afin de se focaliser sur l'essentiel et d'apporter un maximum de valeur au sein du code et même de vos tests.

1. Does your code speak business?

« Specifica*ons themselves are incredibly difficult to get right. [...]
Specifica*ons are not wri>en in computer language. They’re wri>en 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 specifica*ons that are supposed to produce
always the same output. »
