iPhone

The iPhone didn't work when they demonstrated it for the first time, but Steve Jobs made it look like it did by doing things in the right order. The iPhone could play a section of a song or a video, but it couldn’t play an entire clip reliably without crashing. It worked fine if you sent an e-mail and then surfed the Web. If you did those things in reverse, however, it might not. Hours of trial and error had helped the iPhone team develop what engineers called “the golden path,” a specific set of tasks, performed in a specific way and order that made the phone look as if it worked.'
