Procedure
Analyst
Perform impact analysis on a requirement
An impact analysis is commonly performed to analyze a proposed change to a requirement, or to review the implementation of a requirement to make sure it conforms to the requirement.
1) Open the requirement and view the traces in the source link field.
2) Select a source trace and select Item > Source Trace > View.
3) In the Source Trace Viewer, analyze the impact of changing the member by viewing everywhere it is used (Member > Locate).
4) Select any other requirement that is implemented by the same member revision and select Item > View Item Details.
* 
You can also select Document > View to view the requirement in the context of the requirements document.
5) Review the details of the other requirement to determine if the planned changes to the current requirement will affect it.
