At a particular manufacturing plant, a high-profit line experienced a particular breakdown about once every six months. The repair procedure required two electricians to conduct lockout/tagout, unwire a 40-hp motor, remove the motor, and wait for the mechanics to pull a complex assembly. The next set of steps took nearly three hours, after which time the electricians would re-energize the system and start the motor.
