Requirements Diagram

A Requirements diagram is a custom diagram used to describe a system's requirements or features as a visual model.

Requirements are defined using Requirement elements (Custom elements of type Requirement). To view the detailed description of a Requirement, double-click on the element to display its properties.

Requirements can have relationships with other elements such as other Requirements and Use Cases. To view the traceability of a requirement, use the Traceability window.
