A use case is commonly defined as a description of how a user interacts with a system to achieve a particular goal. However, there are several synonyms for use case that can be used interchangeably. For example, scenario, user story, use scenario, and use case scenario are all commonly used terms that refer to the same concept. User narratives, usage situations, and usage scenarios are also frequently used to describe the same idea. Each of these synonyms highlights the importance of understanding how users interact with a system to ensure that it meets their needs and expectations. Regardless of the terminology used, the ultimate goal is to create a system that is functional, user-friendly, and efficient.
