Competing On The Basis Of Speed
“When Toyota designs cars, they use a process called set based design: a Prius is designed in 15 months. For the first 4 months of the cycle they maintain 10 active engines under active development, in detail. They then decide which one of those ten is the best. They don’t just make one, and keep making it better. Toyota defers commitment as late as they can so they have the most information available to them when the decision needs to be made.”
