Lesson 2.3: View traceabilty

In this lesson you will view traceability relationships between requirements and proxy requirements.

Requirement traceability is a relationship between two requirements that implies the source, derivation, or dependencies between the artifacts. Trace to and trace from indicators help identify the source, derivation, or dependency clearly; for example, design elements, such as use cases or classes, typically trace to high-level feature requirements, implying that the feature is the source, or "motivator," for the design element. Traceability relationships help you determine the extent to which your project requirements are satisfied. As elements or their associated requirements change, you can use traceability relationships to monitor the impact of these changes.

In this lesson you will view traceability in the Requirement Trace view, which shows traceability for the selected requirement. You will also view traceability for all feature requirements in a Traceability Tree query.

To view traceability, complete the following steps:

  1. Expand the Features and Vision folder and the Web Shop System folder in the Requirement Explorer view.
  2. Select the requirement FEAT1 Secure payment method. Traceability relationships for this requirement are displayed in the Requirement Trace view.
  3. Click the icons in the Requirement Trace view: Show Requirements Tracing From the Focus Requirement and Show Requirements To the Focus Requirement . Because the FOLDER1 proxy requirement traces to the feature, the traceability relationship is shown only when the Show Requirements To the Focus Requirement option is selected.
  4. In the Requirement Explorer view, expand the Coverage Analysis folder.
  5. Double-click the Full Coverage Report icon . This icon indicates that the artifact is a Traceability Tree view from Rational® RequisitePro®.
  6. In the Requirement Query Results view, expand the FEAT1 Secure payment method requirement. The traceability from the proxy requirement to the feature requirement is displayed.
