The outcome is: Was the order created correctly Is inventory accurate Did the right person get notified Can we trust the system state after all this Most of the time, the code “works”. But the outcome is wrong. That is where the real work starts. We started changing how we build: Every action is tracked end to end Each step is validated before moving forward Failures are handled explicitly, not ignored State is checked across systems, not assumed Less focus on adding features. More focus on controlling what actually happens after they run. Because in real systems, users do not care what you built. They care if the result is correct.…
