Running the Requirement-Requirement Traceability Reports

Configure the Requirement-Requirement Traceability Reports

You can configure the scope of the report to show specific views of the relationships between sub requirements and downstream requirements and the parent requirement.

Required responsibilities:

Baseline: Leader (when the object is in the Frozen state) or Author

Access the Requirement-Requirement traceability reports by doing one of the following:
- To access the reports from the specifications or requirements lists:
  1. Select the specification or requirement in the list.
  2. From the Actions menu, select Traceability Report > Req-Req.
- To access the reports from a specification or requirement:
  1. View the requirement or specification from which you want to run the report. See Opening a Requirement or Opening a Specification.
  2. From the navigation pane, select Traceability.
  3. Select the Req-Req page tab.
After accessing the report from a specification, if you want to target a specific requirement in the specification or all of the requirements in a specific chapter of the specification, click to search for and select the specification.
Note: This option is available but has no effect when the report is run from a requirement.
After accessing the report from a specification, if you want to target a specific requirement in the specification or all of the requirements in a specific chapter of the specification, click to select the requirements and chapters.
Note: This option is available but has no effect when the report is run from a requirement.

Select the type of traceability report that you want to view.

If you accessed the report from a specification, the following options are available:


Report Name	Description
Sub Requirements Only	Displays a report of requirements with related sub requirements.
Downstream Requirements Only	Displays a report of requirements with related downstream requirements.
Bi-directional downstream requirements report	Displays a report of requirements bi-directionally linked to their related downstream requirements.
Derivation Traceability Matrix	Displays a multi-level report of requirements with related downstream requirements.

If you accessed the report from a requirement, the following options are available:


Report Name	Description
Sub/Downstream Requirements	Displays a report of requirements with related sub requirements and downstream requirements.
Sub/Downstream Requirements (Bi-Directional)	Displays a report of requirements bi-directionally linked to their related sub requirements and downstream requirements.
Sub Requirements Only	Displays a report of requirements with related sub requirements.
Derivation Traceability Matrix	Displays a multi-level report of requirements with related downstream requirements.

The selected report displays in the Traceability report page tab.

All Requirement-Requirement traceability reports except the Derivation Traceability Matrix contain the following information:


Column Name	Description
Requirements or Name	Name of the parent requirement
Title	Title of the parent requirement
Revision	Revision level of the parent requirement
Parent Specifications	Name of the parent specifications of the parent requirement
Title	Title of the parent specifications of the parent requirement
<-> Only appears in the Bi-directional downstream requirements report	Direction and status of the link relationship between the parent requirement and the sub requirement or downstream requirement
Requirement Name or Sub/Downstream Requirements	Name of the sub requirement or downstream requirement
Title	Title of the sub requirement or downstream requirement
Revision	Revision level of the sub requirement or downstream requirement
Parent Specifications	Parent specifications of the sub requirement or downstream requirement
Title	Title of the parent specification of the sub requirement or downstream requirement
Type	Type of relationship between the parent requirement and the sub requirement or downstream requirement
Link Status	Status of the relationship link between the parent requirement and the sub requirement or downstream requirement

The Derivation Traceability Matrix report contains the following information:


Column Name	Description
Name	Name of the parent requirement
Title	Title of the parent requirement
Rev	Revision level of the parent requirement
Parent Specifications	Name of the parent specifications of the parent requirement
Title	Title of the parent specifications of the parent requirement
Downstream Requirement	Name of the downstream requirement
Title	Title of the downstream requirement
Rev	Revision level of the downstream requirement
Link Status	Status of the relationship link between the parent requirement and the downstream requirement
Parent Specifications	Parent specifications of the downstream requirement
Title	Title of the parent specification of the downstream requirement

Following are the general rules about how the Derivation Traceability Matrix report is generated:

When you select one or more requirements to generate the report, the selected requirements are considered as root requirements.
When you select a specification to generate the report, all of the requirements in the specification (immediately under the chapters and their sub-chapters) are considered as root requirements.
When you select a specification structure to generate the report, all of the requirements in that specification are considered as root requirements. You will not have to select specific requirements to generate the report.
When you generate the report from a product's Requirements category, if you do not select any requirements under the product, all of the requirements connected to the product are considered as root requirements. If you do select requirements under the product, then only the selected requirements are considered as root requirements.

Determine Traceability Coverage

You can determine the percentage of requirements in a specification that are covered by downstream requirements using the Derivation Traceability Matrix report.

Required responsibilities:

Baseline: Leader (when the object is in the Frozen state) or Author

Run the Derivation Traceability Matrix report.
If necessary, in the Traceability reports page tab, expand the levels of requirements shown using the drop-down list.

Click Next.

The traceability coverage report displays in the Traceability reports page tab. It contains the following information:


Column Name	Description
Specifications	If run from a specification, the name of the specification containing the covered requirements If run from a requirement, the name of the covered requirement
Coverage	If run from a specification, the percentage of requirements in that specification that are covered by downstream requirements If run from a requirement, the percentage that the requirement is covered by downstream requirements
