High Level Use Case
If use cases are too high-level and abstract, they might lack the necessary detail for effective development. Conversely, overly detailed use cases can become unwieldy and difficult to manage. Example Let's illustrate use case granularity with an example related to a quotUser Registrationquot functionality in an e-commerce application
The first area, use case identifiers and initiators, orients the reader and contains the use case name and a unique ID the application area or system that this use case belongs to the actors involved in the use case and the stakeholders that have a high level of interest in the use case.

Instead, a proper use case diagram depicts a high-level overview of the relationship between use cases, actors, and systems. Experts recommend that use case diagrams be used to supplement a more descriptive textual use case. UML is the modeling toolkit that you can use to build your diagrams. Use cases are represented with a labeled oval shape.
UML diagrams define and organize the high-level functions and scope of a system. By modeling the basic flow of events in a use case, they help identify the goals that you need to achieve with every system-user interaction. 5 Use case diagram examples and templates that you can use
Typically, you will start by defining the high-level business use cases. As the system requirements get defined, they will be drilled down into one or more lower-level system use cases. Use Cases vs. User Stories. One related artifact is the quotbusiness scenarioquot or user story. These are similar to use cases in terms of what they seek to
