I know that some companies practice this ivory tower architecture and things like that. But there are also aspects where some teams, most likely in the startups, they don't actually capture those design decisions. So getting back to code for teams who haven't reported design rationale, who haven't kind of written down really any documentation at all,. That's what we end up seeing a lot of, right? You can recreate the structure, you can see the fence, but you have no idea why it's there or how it's safe to change.
“An ADR is a simple text file describing the context, the decision, and the consequences of a single architectural decision stored in the version control repository."
Michael Keeling is an experienced software engineer, architect, and the author of “Design It!: From Programmer to Software Architect”. In this episode, Michael shared in-depth about ADR. He first shared his story of discovering ADR before describing what an ADR is. Michael then shared the objectives and benefits of using ADR to record architecture decisions and explained the key behavior changes happening when we practise ADR. Towards the end, Michael shared a few practical tips on creating and updating ADR, some patterns and anti-patterns he observed from his experience, and suggestions on how we can practise ADR effectively as a team.
