It was early. Early, meaning we were the only two people on the plant floor. Emily drew a flow chart of how materials were received, then assembled and carted off to QC for inspection. She defended the competence of her workers in the assembly process.

“The issue isn’t assembly,” I said. “The issue is speed and accuracy. Have you ever counted rejects off the line?”

“Well, no,” replied Emily. “That’s what our Quality Department does.”

“So, when units leave this line, we have no idea which ones meet spec and which ones are defective?”

Emily searched in her mind for a better answer, but she couldn’t find one. “No,” she replied.

“Emily, we are talking about competence. The biggest reason for failure is incompetence. Most managers will accept all kinds of excuses. The problem is not that the line is running too fast or too slow or that it is too hot or too cold, or that we don’t have great health insurance or that the team isn’t motivated. The problem is incompetence. Most managers won’t call it incompetence, because they don’t know how to solve that problem. The problem you name is the problem you solve. The issue is speed and accuracy. The problem is incompetence.”

“So, what should I do?” Emily asked.

“Funny, you should ask. Tonight, in class, we are going to talk about control systems and feedback loops. Why don’t you come, as my guest? I will help you teach the subject.”
