Principles
All design principlesOptimize for the next engineer
Make dependencies, ownership, and failure behavior easy to understand. The next engineer should be able to build on a decision without reverse-engineering it.
Prefer practical simplicity
Choose the least complex architecture the team can confidently operate. Add machinery when the business problem justifies the cost of owning it.
