Embodiments of the present invention provide a system for indicator regression and modeling for implementing system changes to improve control effectiveness. The system is typically configured for presenting, prompting for and receiving a selection from a list of controls from a user, via a control effectiveness application user interface on a user device. The system is also for receiving two or more consideration indicators from the user device, via the control effectiveness application user interface forming a consideration set; applying a regression algorithm on the consideration set of indicators; reducing a number of the subset of the consideration set of indicators based on a threshold correlation or a threshold number; finalizing the final equation with the number of the subset, each having a corresponding coefficient; and, in response to finalizing the final equation, automatically performing an action configured to improve effectiveness of the control based on the final equation.
