“Nothing matters more to a product’s success—whether it’s a software product, website, cell phone, or garbage can—than good design,” Joel Spolsky argues. “Design is something you only have to pay for once for your product. It’s a part of the fixed costs in the equation, not the variable costs. But it adds value to every unit sold. That’s what Thomas C. Gale, the famous Chrysler automobile designer who retired in 2001, meant when he said that ‘Good design adds value faster than it adds cost.’”
