Why Factory THE CAR ISN'T THE HARD PART. THE FACTORY IS. Most people still treat factories as a cost center. That's the wrong model. @elonmusk: "I love factories. Honestly. A lot of people these days don't love factories or haven't even been to one, but I've walked the line in every factory and I'm a big fan." "This is a great place to be. You make things that have good utility. People love the product. Building a product people love, that's great." That's why the factory matters. • N cost centers — plants treated as overhead • 1 factory-as-product — designed like the car • Walk the line — utility people love • Software scales on servers — hardware scales on a line The car isn't the hard part. The machine that makes the machine is.
