REVERSE engineering softwareCOMPUTER softwareThe Use Case Diagram (UCD) is a visual form of system design that helps software developers comprehend the system behavior. Maintaining and updating the system can be a difficult task when it has no visualization of a system behavior or software ...
Examining a Use Case Example There are several benefits of utilizing a use case methodology. Use cases can help a company identify and resolve problems in a product or system. A use case may also show a designer or developer uses that they had not thought of. This could help them get a...
A use case is a description ofhow a person who actually uses that process or system will accomplish a goal. It's typically associated with software systems, but can be used in reference to any process. For example, imagine you're a cook who has a goal of preparing a grilled cheese sand...
Use cases must also specify post conditions that are observable results and a description of the final state of the system after the use case has been executed successfully. The ATM PIN example is shown below in Figure 4.3. We show successful and unsuccessful scenarios. In this diagram we can...
For example, “As a user, I want to log in to my account so I can view my orders.” That’s a simple user story. Business analysts and developers often use both tools together. While the use case digs into the details, user stories keep things simple. Together, they help teams under...

For use case testing, we would have a test of the success scenario and one testing for each extension. In this example, we may give extension 4b a higher priority than 4a from a security point of view. System requirements can also be specified as a set of use cases. This approach can...
