Use Case Flows

The Main Flow

An unconditional set of steps that describe how the use case goal can be achieved and all related stakeholder interests can be satisfied.  Each step is essential to achieving the use case goal (no step can be skipped), and each step succeeds.

An Alternative Flow

A conditional set of steps that are an alternative to one or more steps in another flow (the alternative flow is performed instead of the other step or steps), after which the use case continues to pursue its goal.

A Recovery Flow

A conditional set of steps that are a response to the failure of a step in another flow (the recovery flow is performed after the other step), after which the use case continues to pursue its goal

An Exception Flow

A conditional set of steps that are a response to the failure of a step in another flow (the exception flow is performed after the other step), after which the use case abandons the pursuit of its goal.

An Option Flow

A conditional set of steps that represent a nonessential option available between two steps in another flow (the option flow is performed between the two steps), after which the use case continues with the second of those steps.
