In the previous lesson, you reviewed the requirements and
learned the difference between functional and nonfunctional requirements.
This lesson contains a short video showing the use cases in the starting
point project and their relationships. Analysis of the use cases gives
you information about both the structure and the behavior of the system.
The spa temperature control system consists of two logical
structural blocks: a system under control and a control system. Since
the use cases reflect the functional requirements, you can map the
requirements to the use cases using SysML trace dependencies.
Open
the UseCaseDiagramsPkg to examine the use-case diagrams and the list
of use cases it contains.
Watch
the "Use cases with requirements video" in the Related information section
to see the use-case diagrams and the requirements that are linked
to the use cases.
