UML use case diagram and use case narrative

UML use case diagram and use case narrative

This is a component of the project that each learner will complete and submit individually. The project definition will most likely be revisited and modified once teams are formed and start working together. For this component, you will identify and describe the subsystem in which you are working for your individual project and discuss how your subsystem will play a role in the overall system. You will also identify the use case or use cases for your subsystem.

Place the use cases in a table. Keep in mind that later in the course you will be required to design a prototype of one of the objects within your chosen subsystem. Be sure to provide enough detail to design this prototype later in the course. Think of use cases as actions a user will take when interacting with the system. Your use cases should show a direct relationship to the goals of your subsystem.

Create a functional model of your subsystem:

Create a UML use case diagram for each chosen use case.
Create a use case narrative for each use case that contains the following descriptors:
Use case ID.
Priority.
Source.
Primary business actor.
Other participating actors.
Interested stakeholder or stakeholders.
Description.
Precondition or preconditions.
Trigger.
Typical course events.
Alternate courses.
Conclusion.
Postcondition.
Business rules.
Implementation constraints and specifications.
Assumptions.
Open issues.
