"Human beings make quite reasonably decisions, but only based on the information they have." This is the concept of bounded rationality, as defined by Nobel prize Herbert Simon. If we look at Agile principles and practices from a systemic perspective, they focus on maximize rationality boundaries related to the product we are building. However, the whole organization and its teams are interacting complex systems which follow the very same principles of Systems Theory. Bounded rationality plays a subtle but fundamental role in every System, beyond just development teams. In this talk I will try to explain how Systems Theory can help organizations and why motivation is the key of success in complex Systems made by human beings.
