Requirement Diagram

A Requirement Diagram is a diagram specially used in SysML in which requirements and the relations between them and their relationship to other model elements are shown as discussed in the following paragraphs.

## Derive Requirement Relationship

If a requirement is derived from an other requirement, their relation is named "Derive Requirement Relationship".

## Namespace Containment

If a requirement is contained in another requirement, their relation is named "Namespace Containment".

## Satisfy Relationship

If a requirement is satisfied by a design element, their relation is named "Satisfy Relationship".

## Copy Relationship

If a requirement is a copy of another requirement, their relation is named "Copy Relationship".

## Verify Relationship

If there exists a relation between a requirement and a test case verifying this requirement, their relation is named "Verify Relationship".

## Test Case

A Test Case is defined by a flow checking whether the system under consideration satisfies a requirement.

## Refine Relationship

If a requirement is refined by other requirements / model elements, the relation is named "Refine Relationship".

## Trace Relationship

If there exists a relation between a requirement and an arbitrary model element traced by this requirement, their relation is named "Trace Relationship".
