This document discusses why management is becoming dispensable and how organizations will become more agile and decentralized. It argues that under the right conditions, people enjoy and are motivated by work, seek responsibility, and have creativity that is underused. Traditional hierarchical management structures are described as mechanical and dividing work from thinking. Alternative structures are proposed that integrate thinking and doing, are alive, and work with an outside-in perspective. The document advocates reinventing work for the current century by establishing principles like freedom to act, responsibility through connected cells rather than departments, leadership instead of management, and purpose-driven resource usage over status-oriented practices.
