Change Audit Functionality

There is a need for a Change Management Audit tool. This solution will take a snapshot of a system prior to a change window, then another snapshot of a system post the change window. It will then have the ability to create work flow to notify someone of a delta report of what was changed and send the report to the someone to verify the said work was the only work that was completed. This would be a separate module offered in conjuction with Change and Helpdesk.
