The document discusses the difference between "clock building" and "time telling" in organizations. Clock building means building an organization that can prosper far beyond any single leader or idea by focusing on shared vision, values, and processes. In contrast, time telling refers to relying on a great idea or charismatic leader. The document advocates that leaders should focus on clock building by getting the right people in place, driving towards shared objectives, and allowing the organization to evolve and adapt over time. Examples are given showing that clock building organizations like 3M have thrived even after key leaders departed.
