This document discusses organizational boundaries and the open and closed nature of organizations. It states that boundaries separate organizations from their environments and provide control, while competencies and power allow organizations to achieve goals through their inputs, throughputs and outputs. Organizations can be open or closed - open organizations are totally open to the environment for survival, while closed organizations are more autonomous and insulated with thicker boundaries. The document also notes that organizations can be partially open or closed depending on their environment, and the contingency approach means an organization must be able to open, close, or adjust depending on external events to perform well.
