What is the business cost of poor thinking? It is a question Jan De Visch and Otto Laske answer in their book 'Dynamic Collaboration'. They make a distinction between downwardly and upwardly divided teams. Downwardly divided teams create unnecessary distraction, and degrade the team culture, causing huge costs to the company. In their book they offer practical tools to raise the quality of decision making and to keep ego's in check. Their book 'Dynamic Collaboration. Strenghtening Self-Organization and Collaborative Intelligence in Teams' will be available from May 31st 2018.
