A Use Case is a list of steps, typically defining interactions between a role (actor) and a system, to achieve a goal. Use Cases are becoming a common tool for describing functional requirements for software systems and for documenting business processes. The technique itself seems simple, however those unfamiliar with Use Cases are usually confronted with questions about what they are supposed to write – how much and at what level of detail?
This concise course provides the guidelines for Use Case writing and will include many examples of good Use Cases. The course is a mix of instructor lecture and exercises. It begins with an introduction to what Use Cases are and how they add value to the process. This is followed by a comprehensive explanation of the Use Case segments including actors, goals, exceptions, scenarios, alternate paths, preconditions and success guarantees.
This course is intended for people who are involved with documenting project requirements and want to learn how to prepare effective Use Cases for their projects. Project personnel including Business Analysts, Project Managers, project and resource managers, clients involved on projects, and others with project responsibilities will find this course relevant to their project work.
