Design thinking, as a concept, has been slowly evolving and coalescing over the past decade. One popular definition is that design thinking means thinking as a designer would, which is about as circular as a definition can be. More concretely, Tim Brown of IDEO has written that design thinking is “a discipline that uses the designer’s sensibility and methods to match people’s needs with what is technologically feasible and what a viable business strategy can convert into customer value and market opportunity.”
A person or organization instilled with that discipline is constantly seeking a fruitful balance between reliability and validity, between art and science, between intuition and analytics, and between exploration and exploitation. The design-thinking organization applies the designer’s most crucial tool to the problems of business. That tool is abductive reasoning.
