Use case diagrams depict: Use cases. A use case describes a sequence of actions that provide something of measurable value to an actor and is drawn as a horizontal ellipse.
Actors. An actor is a person, organization, or external system that plays a role in one or more interactions with your system. Actors are drawn as stick figures. In the example depicted in Figure 1 students are enrolling in courses with the potential help of registrars. Figure 1. Figure 2. Figure 3. Creating Use Case Diagrams I like to start by identifying as many actors as possible.
The preceding paragraph describes my general use case modeling style, an "actors first" approach. Reuse Opportunities Figure 4 shows the three types of relationships between use cases -- extends, includes, and inheritance -- as well as inheritance between actors. Figure 4. Remaining Agile So how can you keep use case modeling agile?

Use cases: requirements in context - Daryl Kulak, Eamonn Guiney. This book describes how to gather and define software requirements using a process based on use cases. It shows systems analysts and designers how use cases can provide solutions to the most challenging requirements issues, resulting in effective, quality systems that meet the needs of users. Use Cases, Second Edition: Requirements in Context describes a three-step method for establishing requirements—an iterative process that produces increasingly refined requirements. Drawing on their extensive, real-world experience, the authors offer a wealth of advice on use-case driven lifecycles, planning for change, and keeping on track.
In addition, they include numerous detailed examples to illustrate practical applications. This second edition incorporates the many advancements in use case methodology that have occurred over the past few years. The book opens with a brief introduction to use cases and the Unified Modeling Language (UML). The book shows you how to: Reports, Articles, and Papers from Constantine & Lockwood, Ltd.
