05 At the bench
Deployment isn’t the finish line.
The first successful request proves the happy path. The real work starts after that: watching how the system behaves, tracing failures, replacing weak assumptions, and making the next fix easier than the last one.
01Trace
Follow the problem across application, data, network, and hardware boundaries.
02Repair
Fix the cause, document what mattered, and avoid hiding the failure behind retries.
03Improve
Use what broke to simplify the system and make its next failure easier to understand.
