HappinessNo mockery in this world ever sounds to me so hollow as that of being told to cultivate happiness. What does such advice mean? Happiness is not a potato, to be planted in mould, and tilled with manure.
― Charlotte Brontë, Villette

Experimentation Without Risk
Branch — Question, Hypothesis, Experiment, Analyze,
Conclude
Pull Request — Gather feedback from peers and
integrate with 3rd party products to perform
automation for quality of code, build status, and
deployment

Pull Request feedback loop
Writing a Pull Request — Include the purposes and why
the work is taking place. Include any references. Be
explicit about when and what kind of feedback you want.
Use @mentions to bring people into the conversation.
Providing feedback — Make sure you understand the
context of the pull request and explain any code changes
you propose. Use positive language.
Responding to feedback — Express that you appreciate
their feedback. Ask for clarification if needed or clarify
why you made certain decisions. Try to respond to any
comment.

Steps to create happy developers
32
• Ensure quality• Implement rigorous testing and build• Short-lived branches for small features• Make deploys boring and predictable• Require documentation in the
repositories• Require mature and respectful
behavior
• Improve collaboration • Let developers share their work• Require public and focused code
reviews• Give employees the confidence to
contribute code• Put everyone in one spot with chat• Share your experiences
