Use Case Structure
Its most fundamental structure supports the “design-by-contract” pattern:zDescription/Goal: A short description and/or goal of the use case. The goal being what one wishes to achieve (thank
you Mr. Cockbrun).
zPrecondition:
The state of the universe before activity can begin.
zActivity: The
things that happen (The “time-ordered sequence of events”.
zPostcondition:
The state of the universe after things happen.
The
above is a simplification. If you want to find out how poorly understood this is, try to get agreement on
a format.
