A use case is a description of how a user might use an application to complete a specific task and can vary in the application-specific detail from simple "pseudo-code" descriptions to click-level interaction. I've also heard them described as the "correct answer" for a task. They are used in software engineering as a way of describing, documenting, and testing system functionality. Use scenarios describe the greater context of a task including the conditions, motivation, and environment of the task for a particular user group. These usually include all the details interaction designers need to understand what the user is trying to do and what they need. Most developers have never heard of a use scenario, but will adapt use cases to include this rich, contexual user information. I've noticed that some IxDers tend to use both cases and scenarios when they actually mean use scenarios, usually the ones who have the most developer-designer experience. I've noticed myself slip when I talk to developers; since they usually aren't aware of use scenarios or the difference between cases and scenarios, they use both interchangably. I guess I unconciously switch my language so they know what I'm talking about. -- Celeste 'seele' Paul www.obso1337.org ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
