Difference Between Use Cases and Scenarios

Scott Sehlhorst Syndicated feed does a good job of discussing the difference between use cases and scenarios. I think this is important for those following the Microsoft Solutions Framework (MSF), which uses scenarios. Personally, I think scenarios are too specific and don't offer the amount of flexibility you need to make your requirements easy to manage. One of the nice things about use cases is you can make them as fine- or course-grained as you want. To sum up what Scott says, a scenario is a single run thru a use case. So, while a use case may have several alternate flows, only one of those flows, from end-to-end, would make up a scenario. Pretty simple, but I feel it's an important fact to acknowledge.
