Narrow an ambiguous field failure
- Situation
- A customer symptom may originate in RF conditions, gateway state, Wi-Fi, Ethernet, provisioning, cloud services, a downstream client, or the test itself.
- What I do
- Correlate telemetry, device state, logs, timing, and controlled reproduction. Rule out explanations that the available data does not support.
- What changes
- The owning team gets a narrower problem statement, the leading explanation clearly marked as provisional, and the next test or owner.
