The Infotel Six Step Troubleshooting Method: “CCLLFF“
Inspired from a US Navy repair manual, this is our customer communication and repair process to maintain “Perfect Installs, Uncommon Reliability.”
The First Three Steps Use Your Mind:
- Clarify – Witness issue first hand. Be a “Fair Witness.” Document the system in words or pictures.
- Changed – What changed in your environment at the time of the system failure? Use the principal of “Occam’s Razor.”
- List – List probable faults and agree on what is not the problem. Divide and conquer.
*** EVERYONE MUST AGREE UPON THE FIRST THREE STEPS BEFORE TAKING ACTION ***
The Last Three Steps Use Your Hands:
- Localize – Eliminate from your list. What remains is the solution to your problem.
- Fix it – Apply the above solution.
- Failure analysis – Fix for good by finding and correcting the root cause of the failures. (e.g. We replaced the blown fuse but why did it blow in the first place?)
