How are breakthroughs accomplished? Does it have to be Chaos? Is it as smooth as linear steps? Either can be just as hard as running on Jupiter or jumping on the moon but both require a specific set of tools and effort. In “Modelling Product Innovation Processes, from Linear Logic to Circular Chaos” exact tools such as The Delft Model and Schon’s Model are compared and a reviewed. In combination is where the true genius is revealed.
