Ryan, In my experience use cases are an effective way to help define and communicate requirements and business rules. The clearer a system is understood the easier it is to model. They are simply a formal way to describe process interactions in plain language. There is no magic about them. They just help us understand who does what and why. They get mentioned a lot lately in the same sentence as object oriented programming because the UML has diagrammatic support for them and both the UML and use cases are components of popular OOP analysis and design methodologies.
