What happened recently at Mr. Polk’s factory?

W: Hi, Mr.Polk. Thanks for meeting with me.
M: Sure. It’s a pleasure. So, you’re writing an article for Forge Ahead Magazine?
W: Yes, the piece is about how your car manufacturing plant dramatically changed the way it produces cars. Could you tell me about what you did?
M: Certainly. Many factory employees are told to never stop the production line—no matter what. Recently I took the opposite approach. Whenever we found a defect, anyone could stop the assembly line and address the problem immediately.
W: And this transition improved your quality control?
M: Exactly. In fact, look at this production chart. You’ll see that, compared to other factories, cars from this one have far fewer defects.
