Andorian development principles and practices

New public workshop: Architecting for fast, sustainable flow - enabling DevOps and Team Topologies thru architecture. Learn more and enroll.

A work-in-progress collection of development principles and practices that I find myself saying repeatedly.

  1. Done = released to the user
  2. Commit changes (/ merge PRs) daily
  3. Write *** tests:
    • (almost) every commit should have tests
    • when fixing a bug, first write a failing test
    • the less obvious the code, the more tests are needed
  4. Aim to write code that is obviously correct
  5. Avoid code duplication: extract methods, classes, libraries, …
  6. Understand the technology you are using:
    • Learn it, e.g. read the manual
    • Ask a team member for help
  7. Really, write *** tests:
  8. Solve problems effectively:
    • Define the problem you are solving
    • Determine whether it’s the right problem to solve or a consequence of the real problem
    • Identify possible solutions, and compare their benefits, drawbacks and issues
    • If it’s a significant problem, document why you solved the problem the way you did
  9. Leave the code better than you found it.
  10. Break a large task into a carefully ordered sequence of subtasks that deliver value incrementally
  11. Don’t break the build: run tests before pushing changes. And if you do break the build, fix it quickly.

New workshop: Architecting for fast, sustainable flow

Enabling DevOps and Team Topologies thru architecture

DevOps and Team topologies are vital for delivering the fast flow of changes that modern businesses need.

But they are insufficient. You also need an application architecture that supports fast, sustainable flow.
