This document summarizes key points from the book "The Design of Business" by Roger Martin. It discusses three approaches to business - the school of strategy, the school of creativity/innovation, and the school of design thinking. Design thinking balances analytical and intuitive thinking, and sees business as something that is continuously redesigned. It also discusses the knowledge funnel process, abductive thinking, and how design thinking can help organizations balance exploration and exploitation to continuously solve mysteries and drive business innovation.
