What is a use case?

A use case is a description of how a user interacts with a system or product. Companies build use cases to establish success scenarios, failure scenarios, and any important variants or exceptions.

Many organizations leverage use case modeling tools — such as Miro, LucidChart, and SmartDraw, for some examples — to write or visually represent a use case.

Use cases are frequently employed in software development environments to simplify complicated concepts, but they can be just as important in project management for gathering requirements and defining a project’s scope.
