use case is a list of actions or event steps, typically defining the interactions between a role (known in the Unified Modeling Language as an actor) and a system, to achieve a goal. The actor can be a human, an external system, or time. In systems engineering, use cases are used at a higher level than within software engineering, often representing missions or stakeholder goals. Another way to look at it is a use case describes a way in which a real-world actor interacts with the system. In a system use case you include high-level implementation decisions. System use cases can be written in both an informal manner and a formal manner
Benefits Of Use Case
Use cases have been used extensively over the past few decades. The advantages of Use cases includes:
The list of goal names provides the shortest summary of what the system will offer
It gives an overview of the roles of each and every component in the system. It will help us in defining the role of users, administrators etc.
It helps us in extensively defining the user’s need and exploring it as to how it will work.
It provides solutions and answers to many questions that might pop up if we start a project unplanned.
