It may seem counterintuitive, but there is a speed limit to repairs. If you exceed it, you actually increase downtime. This is especially true when repairs include modifications that are poorly, if at all, documented.
Yes, you may save time in the moment by quickly restoring operations and not worrying about wire labeling, workmanship, documentation, or other functions that take time while the operations supervisor is breathing down your neck. But the next time there’s a failure, restoring operations will take considerably longer.
If the repair isn’t done to the same rigorous standards as construction is (or at least should be), it’s not restoring the equipment to its original condition. Instead of being a true repair, it’s a degradation of the equipment.
Always document the “As Found” and “As Left” conditions. If the repair requires equipment modifications, take notes, make sketches, and photograph the system in both its “As Found” and “As Left” configuration.
And don’t take workmanship shortcuts. If the repair requires unbundling cables, rebundle them and properly support the bundle so that it’s protected and provides a neat appearance.
