Operating model
Clear scope. Sharp execution. Useful documentation.
Observe the system
Identify the actual failure mode, not just the loudest symptom.
Build the simplest working path
Prefer testable, maintainable fixes over impressive complexity.
Document what matters
Leave behind proof, context, and repeatable steps so teams can trust the result.
