This document discusses reinventing organizations by moving away from traditional hierarchical structures and toward self-managed teams. It presents several alternative organizational models that emphasize small, independent teams with high autonomy over decision-making. These new models are said to improve engagement, adaptability, communication, costs and decision-making compared to traditional top-down structures. The document also provides case studies of companies that have implemented these alternative non-hierarchical models, such as Valve, Buurtzorg, and Morning Star.
