An influential measure of innovation developed by the Drucker Institute provides an annual ranking of companies based on the principle that innovation creates resources for building new and greater wealth. Predictors that underlie the creation of wealth include research and development spending, hiring in cutting-edge fields such as robotics and artificial intelligence, the number and value of patents, customer satisfaction, and employee engagement. Innovation requires overcoming various constraints such as insufficient funding and a lack of time to complete goals. Leaders can become amplifiers by engaging followers, possessing the kind of knowledge that fits corporate needs, and avoiding cognitive entrenchment – knowledge stability that causes experts to be inflexible in their thinking. The dynamic problem-solving model synthesizes a variety of theoretical constructs such as the types of constraints on problem solving, the distinction between a problem-first and an idea-first approach to invention, and the zigzag pathway to creativity.
