If it could save a person's life, would you find a way to make it faster? "If it could save a person's life, would you find a way to shave ten seconds off the boot time?" [Jobs] asked. Kenyon allowed that he probably could. Jobs went to a whiteboard and showed that if there were five million people using the Max, and it took ten seconds extra to turn it on every day, that added up to three hundred million or so hours per year that people would save, which was the equivalent of at least one hundred lifetimes saved per year. "Larry was suitably impressed, and a few weeks later he came back and it booted up twenty-eight seconds faster," Atkinson recalled. "Steve had a way of motivating by looking at the bigger picture."

The situation talks back As the designer shapes the situation in accordance with his initial presentation of it, the situation “talks back” and he responds to the situation’s back-talk. In a good process of design, this conversation with the situation is reflexive. In answer to the situation’s back-talk, the designer reflects-in-action on the construction of the problem, the strategies of action, or the model of the phenomena, which have been implicit in his moves.
