The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.
The client moved into a new office in Pujiang, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.
