Book excerpt: Thinking to stay ahead of change In a complex business climate, people need to make informed decisions and learn how to think flexibly. A leader's most important asset is the ability to sense changes in the environment and adapt to them quickly. The Prepared Mind of a Leader presents an original and effective way to think more flexibly about innovation, strategy, change, and problem solving. It helps leaders anticipate challenges and prepare for both the intended and unintended consequences of change by laying out a program for developing, maintaining, and mobilizing eight key skills: Observing, Challenging, Reflecting, Reasoning, Imagining, Deciding, Learning, and Teaching. These skills provide a framework that the thoughtful leader or manager can use to approach issues of strategy, innovation, and more. Chapters feature interactive tools that will help readers develop each of the key skills.
