Impact Set Connections is an experimental analysis module evaluates the probabilities during Impact Analysis and Change Propagation stages of Incremental Change process.
In a nutshell, this module measures coupling between each component, marked as Next Visit, and an impact or a change set, i.e. all the components marked as Impacted or Changed.
More precisely, for each component, it is evaluated how many components, marked as , and members of these components, are either used by or are using this component or one of its members.
This is done with the idea that a higher degree of coupling may indicate higher probability of change propagation as indicated in . However, it is useful to remember that this measure is very approximate and thus should be treated only as a hint rather then a precise indicator of the propagation.
