Alternative: Scenarios
|
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. Because of the less
strict structure they are often quicker to develop thereby eliminating the
boredom factor. (10) Usually scenarios are used in
conjunction with use cases. 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. |
