Freud asked, “What does a user really want?” Ten-plus years into web development, we still don’t know. One of the biggest problems in creating and delivering a site is how to decide, specify, and communicate exactly what we’re building and why. Use cases can help answer these questions by providing a simple, fast means to decide and describe the purpose of your project. In this quick-reading article, Messieurs Carr and Meehan introduce use cases and their, uh, uses.
The use-case model can be a powerful tool for controlling scope throughout a project’s life cycle. Because a simplified use-case model can be understood by all project participants, it can also serve as a framework for ongoing collaboration and a visual map of all agreed-upon functionality. Use it to plan, to negotiate, and to prevent scope creep.
