Designers don’t know why a small change to an interface results in a massive drop in a core business metric, product managers don’t know what should go into the backlog and what not, developers don’t know how to estimate the delivery time of the fancy new feature. The whole team behind the product is so clueless that they don’t even know if the new feature brings any value to the users.
“If I had asked people what they wanted, they would have said faster horses” is a quote attributed to Henry Ford. It’s a quote that many people use as an excuse not to do user testing. Because designers and product managers are supposed to be these geniuses that pull ideas out of thin air. Steve Jobs was one of those design/product gurus. All the designer and product manager wannabes have a quote or two from Steve that they hold close to their heart so they feel more secure about themselves. But neither Steve or Henry became famous for their ideas because they would be original. They weren’t. Steve didn’t make the first computer and Henry didn’t make the first car (he made the first car assembly line).
