is yet another method to discover new idea. To do it is very simple, think of something that’s very obvious and then reverse it. For example if you want to find new ideas to improve your restaurant, you might think “restaurant has cooks to cook food” (very obvious, every restaurant has it) then reverse it so you’ll have “restaurant that hasn’t got any cook!”. This might means your restaurant is self-service so people have to cook their own food. Boom! You’ve just got yourself a new idea! Very simple huh…
