It is possible to define the emergent behavior of an object as it is perceived by its environment, as well as its internal behavior in response to external requests.

A behavior can also define the method used to implement an object feature.

A behavior can be specified in several ways, state machine, collaboration between objects, interaction sequence, control flow of an activity, etc.

When a behavior is invoked, it receives input parameters values and returns output parameter values.

The observable effects of a behavior execution may include changes of values of various objects involved in the execution, creation and destruction of objects, generation of communications between objects, etc.
