A manufacturing plant was in full swing one day. The company's massive machine was humming along, taking in the raw materials at one end and churning out the finished product at the other. Suddenly, the machine stopped and ground to a halt. Workers climbed all over it like ants to get it started again. The plant's manager stormed out of his office to find out why his multi-million-dollar machine wasn't making him any money. He listened to his people saying they couldn't figure it out, and he told them to call a technician.
