This document discusses different levels of organizational change, including individual, organizational, and societal change. It notes that all change starts with the individual, as organizational change can only occur if people voluntarily change their own behavior and ways of coordinating. Societal change then happens as people and organizations change. The levels of change are interconnected, as organizational change requires individuals making personal decisions to join in, and social evolution is impacted as organizations and individuals transform their missions and actions. Collective action through individuals each doing what they can within their sphere of influence is key to driving major change.
