Impact analysis is conducted by the department that has been directly hit by it so that it can identify and analyze probable costs associated with the change that has happened and find ways and means to rectify it as appropriately as possible.
It can also be seen as a fair assessment of the advantages and disadvantages of pursuing a course of action in light of its probable consequences.
It is all about estimating what the result of a change is and what needs to be modified to accomplish a change. The impact is evaluated on design & architecture, requirements, and schedule and test.
Sometimes new features are incorporated into an application and it becomes necessary to check for changes in its performance.
The impact analysis helps a company to do so with ease.
