One of the best treatments of use cases I've seen is this presentation
by Dr. Janice (Ginny) Redish. It's a few years old, but not at all out
of date.

Storytelling: The Power of Scenarios
http://www.redish.net/content/handouts/redish_Goldsmith_Oct2001.pdf
---------------------------

A small caveat that makes no difference to the process that you use to
elicit use cases but may impact how you document them is...

Though very related, scenarios are thought to be different from use
cases. A use case is like a boilerplate outline of some specific
business activity. A scenario is an instance or a specific
implementation of a use case with hypothetical variables that tend to
test the use case.

An overly simplified example,

Use Case (step): User enters pass code into the ATM.
Scenario: User enters wrong pass code into the ATM after 2 failed
attempts.
