When to Use a Use Case Diagram - Cooling System Example

This example explains when to use a SysML use case diagram and provides a simple fan example to walk through.

Use case diagrams will help you frame the problem space and detemrine what it is you're trying to build. This would be helpful at the beginning of a IRAD project where everything is very undefined and abstract.

Use cases have verb phrases such as "Provide White Noise" and "Cool Target".

This video was created within Cameo Enterprise Architecture 2021x. The other versions including Cameo Systems Modeler, MagicDraw, 19.0, and 2022x will behave in a similar fashion. This example will provide information regarding Digital Engineering (DE), Model Based Systems Engineering (MBSE), and SysML.
