The document discusses the organizational life cycle, which includes four main stages: birth, growth, decline, and death. It describes several models that explain how organizations progress through these stages and the typical challenges organizations face at each phase. For example, organizational birth involves founding a new organization and overcoming the liability of newness. The population ecology model views organizational birthrates over time as influenced by environmental factors. Organizational growth involves developing skills to acquire more resources but can lead to isomorphism. Decline results from inability to adapt to changes and may occur through several stages from unrecognized problems to crisis and dissolution.
