How I work
Diagnose
Confirm scope, reproduce the failure and separate the cause from the noise.
Restore
Return the business to a safe operating state before chasing elegance.
Document
Leave clear findings, next steps and useful information for whoever follows.
Communicate
Explain the situation in plain language without talking down to anyone.
