Performing impact analysis
Perform an impact analysis to view items related to requirements and understand the impact of a requirement change before you make it.
1. Click the Traceability tab
The impacted items are displayed.
2. Select an impact type to display.
- Show forward impact displays items directly impacted if the requirement changes.
- Show backward impact displays related items that may directly affect the requirement if changed.
The items with a direct impact are displayed. Expand a direct impact to display items with an indirect impact. Click 
to expand all direct impacts or 
to collapse all expanded impacts.
Tip: Arrows in the Relation column can help you determine how items are related. A solid arrow indicates the items are linked. Linked items are only displayed if the link definition allows dependent items to be marked as suspect. A dashed arrow indicates the items are related in a document.
3. Click an item number or summary to view it.
4. Click Save to save any changes.
Tip: If you determine that changes impact items related to the requirement, you may want to mark the items as suspect. This adds a flag to the items to indicate they should be reviewed. See Marking items as suspect.
