Impact Analysis
 The ability to identify all related

be impacted by a change in an
Elements
Relationship Hub
 Perform smart search across RH
elements and relations according
to predefine types:
Upstream impact analysis
Downstream impact analysis
Customize – reflects the
customer’s analysis definitions
 Uses advance visualization
Modify the results ,

Example
Requirements coverage by tests 
A test covers a requirement –
Requirement must be associated to a single model –
element (or is defined non-functional)
A test is derived from a single function –
If a test covers a requirement, it must be derived from the –
function which is linked to the same requirement

Change in Stake Holder requirement
 Stake Holder requirement Adjustable Camera changes
“Camera elevation shall be adjustable from pointing straight down
to 15 degrees above the horizon”
“Camera elevation shall be adjustable from pointing straight down
to 17 degrees above the horizon”
What are the elements impacted as a result of this change?
