Use Case

Definition. A Use Case describes how a user uses a system to accomplish a particular goal.

1. A use case in software is a description of a specific interaction between a user and the software system. It outlines the steps that a user takes to accomplish a specific task or goal using the software. Use cases help software developers to understand how users will interact with the software and how the system should respond to user actions.

2. A use case is a concept used in software development, product design, and other fields to describe how a system can be used to achieve specific goals or tasks. It outlines the interactions between users or actors and the system to achieve a specific outcome.

Each use case typically includes

  • a goal or objective,

  • a list of preconditions that must be met before the use case can be executed,

  • a list of steps that the user takes to accomplish the goal,

  • and a list of post-conditions that describe the expected results of the use case.

Use cases may also include alternative scenarios or error conditions that can occur during the use case execution.

Use cases are an important part of the software development process, as they provide a clear understanding of the software's functionality and how it should be designed and developed to meet user needs. They are often used in agile software development methodologies to guide iterative development and ensure that the software meets user requirements.
