31 Patterns for Writing Effective Use Cases
Use Cases are a wonderfully simple concept: describe a system's functional requirements by telling stories about how using it delivers value to its actors. Yet, for such a simple concept, good use cases can be hard to write. This tutorial is a chance for practiced use case writers to gather and ask the hard questions. How should we structure use cases? What should be the scope of a use case? What level of detail should a use case express? What expertise is required in the use case writing team? How do we provide different levels of detail for different people? How do we keep use case writers from infringing on design? Where do we put the UI design, data descriptions and all the other requirements?
Usually, the answers to these questions begin with the very unsatisfying "Well it depends...", or involves using a monolithic process that offers guidance, but creates mounds of unnecessary work.
This tutorial presents a pattern language that allows the attendees to tailor the answers to these questions to their own situation and development culture. It captures the knowledge and experience of successful use case developers in a way that it can be easily re-used by others, and serves as the basis of a vocabulary describing the properties of quality use cases.
Attendees must have written some use cases and be familiar with basic use case concepts.
The tutorial is structured as a lecture with slides, and an open question-and-answer session. The lecture introduces a set of patterns designed to help the attendees evaluate existing use cases as well as write better ones. The open question-and-answer section allows the attendees to ask questions currently plaguing them at work, and even trade answers and experiences amongst themselves.
