+ | ====== The Five Ideals ====== | ||
+ | |||
+ | The Five Ideals summarized from the book "The Unicorn Project" | ||
+ | |||
+ | ---- | ||
+ | |||
+ | ====== Locality and Simplicity ====== | ||
+ | |||
+ | * Development teams should be able to make changes to their code base and deploy, without impacting or coordinating with others. | ||
+ | * Decouple applications and create abstractions to achieve locality. | ||
+ | * Simplify code bases through abstractions as well. | ||
+ | * The easier the code is to reason about, the easier changes are, and the less it breaks. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | ====== Focus, Flow, Joy ====== | ||
+ | |||
+ | * Remove distractions, | ||
+ | * With the above removed, developers will be able to focus and enjoy the work, producing better code. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | ====== Improvement of Daily Work ====== | ||
+ | |||
+ | * Build time into projects/ | ||
+ | * These are the brittle things that break in an application/ | ||
+ | * Improve anything that impedes a developer from coding. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | ====== Psychological Safety ====== | ||
+ | |||
+ | * Teams should be able to talk about bugs/ | ||
+ | * Blame-less postmortems after a production down event or major bug are critical to implementing actual fixes and preventing the same thing from happening. | ||
+ | * This should be a learning experience for everyone, not a blame session. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | ====== Customer Focus ====== | ||
+ | |||
+ | * Core focus - everything a customer is willing to pay for. | ||
+ | * Example: Web services, APIs, databases, storage. | ||
+ | * Context focus - everything else. | ||
+ | * Example: Any system that supports employees. (such as HR systems) | ||
+ | * While context is important, don't let it take over focus from core customer concerns. | ||
+ | |||
