Libraries are made of up people who must coordinate their work in order to use resources and manage tasks efficiently. Like all organizations, libraries use coordination tools to get this done. Coordination tools include policies, budgets, organizational culture and participation rules. As a library’s outcomes are not directly connected to resources, processes are not directly related, and user interactions vary greatly, libraries operate as loosely-coupled systems. As loosely-coupled systems, libraries enjoy a flexibility and an ability to innovate, but also must account for weaknesses such as inefficiencies and a difficulty in instituting change.
