How Use Case 2.0 Works
What is Use Case 2.0, what are the advantages offered by the concept and how can it be used in practice?
A Use Case describes the visible behaviour of a system from the user’s view point.
Every Use Case has a basic flow. Use Case 2.0 follows a sequence of steps that lead directly to the conclusion.
There are always alternatives if the straight path doesn’t work out. Use Case 2.0 refers to these as alternative flows.
There is no limit to the number of alternatives possible. Every alternative that stretches from start to finish is described as a Use Case story.
During the slicing process several Use Case stories gets summarized into one unit – a Use Case slice.
The slicing takes place along a vertical axis from the first to the last step – not horizontally across Use Cases.
