It is easy to mix up the definitions of use case and use case scenario. A use case represents the actions that are required to enable or abandon a goal. A use case has multiple “paths” that can be taken by any user at any one time. A use case scenario is a single path through the use case. This article provides an example use case and some diagrams to help visualize the concept.

Subordinate and Superordinate Use Cases
Use Cases can be built up by combining other use cases. When a use case is made up of other use cases, the component use cases are known as subordinate use cases. The “parent” use case is referred to as the superordinate use case. This is known as composition. See an example of how composition works for use cases.

Sample Use Case Examples
We talked about informal use cases a while ago in our use case series. Over a series of posts, we are demonstrating the process of defining a software product. The next step, and subject of this post, is the creation of informal use cases to support the defined goals for the software.
