We are constantly challenging ourselves to questions our assumptions about our users, our products, the way that we do things. How can PMs optimize their professional development? How can organizations understand how to better support their people? The way we learn originates in the way we play. For decades cognitive scientists have studied how play develops our minds and the way we interact with the world. Understanding the origins our learning process can help us understand how to continue the process as adults. This talk will cover the concept of play as cognitive developer, examine how great minds have used playful thinking to innovate new concepts and offer thoughts on how organizations can apply these lessons to their team cultures to create space.
