Managing Traceabililty and Impact of Change for DOORS data
In order to understand the traceability relationships between items and be able to manage changes to those items, usage reports have been provided.
Viewing Traceability Links from Modeler Items
1. Launch Modeler and open a model that contains items with OSLC Links or OSLC Surrogates for remote DOORS data.
2. Select the OSLC browser and navigate to the appropriate Modeler item.
3. To view outgoing OSLC Links and Surrogates, right-click on the Modeler item and select Report > Uses. Note that OSLC Surrogates are always outgoing. In the example below, outgoing OSLC Links are displayed for a Use Case called "Drive"
4. The outgoing OSLC Links and Surrogates are displayed in the Results window. The OSLC Link is to a requirement in a remote DOORS server, which is refined by the Use Case "Drive".
5. To view incoming OSLC Links, right-click on the Modeler item and select Report > Uses. In the example below, incoming OSLC Links are displayed for the Use Case called "Drive".
6. The incoming OSLC Links are displayed in the Results pane. The OSLC Link is from a related DOORS requirement. Internal links from items in the Modeler model are also shown.
Viewing Usage of Remote DOORS Items
To understand where remote DOORS items are used within the local Modeler model, perform the following steps:
1. Navigate to the OSLC browser.
2. Right-click on a remote DOORS item and select Report Usage. In the example below, linked items are displayed for the remote DOORS requirement called "The system must provide satellite navigation".
3. The local Modeler items that are linked, the Use Case called "Drive" and the Block called "Infotainment System", are displayed in the Results pane.
