Silicon Valley is far removed from these worlds, yet the same basic idea is widely used in technology circles. “You’ve got to start with the customer experience and work backwards to the technology,” Steve Jobs told the audience at Apple’s 1997 Worldwide Developers Conference. “You can’t start with the technology and try to figure out how you’re going to try to sell it. I made this mistake probably more than anybody in this room, and I’ve got the scar tissue to prove it.”9 Today, “work backwards” is a mantra in Silicon Valley.
