Characteristics of Open Systems

• Input from outside- Open systems are self adjusting and self regulating. When functioning properly open system reaches a steady state or equilibrium. 

• Entropy- Dynamic systems run down over time resulting in loss of energy or entropy. Open systems resist entropy by seeking new input or modifying the processes to return to a steady state

• Process, output and cycles- Open system produce useful output and operate in cycles, following a continuous flow path. 

• Differentiation- They have a tendency toward an increasing specialization of functions and a greater differentiation of their components. For example the role of machines and people tend toward greater specialization and greater interaction. 

• Equifinality- Goals are achieved through differing courses of action and a variety of paths.
