In the typical repair scenario, production equipment unexpectedly goes down and a maintenance tech rides in on a white horse (figuratively), fixes it, and quickly returns the equipment to service.
Suppose Bill’s repair job involves making some bolted connections (for example, when he reconnects a motor.) Nobody is going to leave that equipment down until Bill’s supervisor or another electrician can come by and measure the conductance across each connection.
Suppose Bill is sloppy; he doesn’t replace the locking devices, doesn’t clean the mating surfaces, and doesn’t use a torque wrench. Nevertheless, the equipment runs, and his repair was fast, so he’s perceived as a hero. Right away, those poor connections start causing problems that ultimately result in motor failure a few months later.
It takes less time to repair something correctly than to repair it multiple times due to rushed, sloppy work. To help people keep this mindset and take pride in their work, periodically video a repair from start to finish and have the repair tech state what they are doing and why.
