A use case is a description of how a user interacts with a system to achieve a goal. It is typically used in software engineering to document the functionality of a system. A use case describes the steps that a user takes to complete a task, such as logging into an application or making a purchase. It also outlines the expected results of each step and any potential errors that may occur.
Use cases are beneficial for project managers because they provide an organized way to document the requirements of a system. They can be used to identify potential problems before development begins, which can save time and money. Additionally, use cases can help ensure that all stakeholders understand the scope of the project and what needs to be accomplished.
Creating use cases requires careful planning and analysis. The first step is to identify the goals of the system and determine who will be using it. Then, each user’s interactions with the system should be documented in detail. Finally, any potential errors or exceptions should be noted so that they can be addressed during development.
