Dr. John Camillus, professor of strategy and former Associate Dean at the Katz Graduates School of Business at the University of Pittsburg and author of Wicked Strategies (https://www.amazon.com/Wicked-Strategies-Complexity-Competitors-Rotman-UTP/dp/1442650559) has spent two decades studying the challenge of building strategy in fast-paced, complex, and uncertain environments and helping clients do so.
He argues that fundamentally, large companies and traditional strategy approaches are ill-equipped to deal with the uncertain that we must compete in today. Strategy today is akin to solving a "wicked problem." Wicked problems are beyond complex. And Camillus wrote in a Harvard Business Review article, "A wicked problem has innumerable causes, is tough to describe, and doesn’t have a right answer, as we will see in the next section."
So how do find strategies to win? The key is to shift your approach.
