There are a few alternatives to use cases. One of the most widely used is the scenario. Scenarios are very similar to use cases except they describe situational details making them more specific. Because a scenario describes a specialized situation there are no disagreements over whether all possible enactments are covered. By focusing on particular situations scenarios spotlight problems investigate stress points and suggest solutions. There is not a strict structure to scenarios giving the participants a little more freedom to develop them.

They are a useful tool for exploring refining and challenging the specifications in use cases. But there is nothing that does not allow for them to be used on their own.
