The GAP-ACT (Target) Model of Human Behavior & Performance



The GAP-ACT Model, also known as The Target Model, is based on Perceptual Control Theory (PCT) as developed and articulated by the late William T. Powers (1926-2013).  It is worth mentioning that Powers himself approved of the GAP-ACT Model.

On the Performer side of the model above, we have Goals, Actions and Perceptions (GAP).  On the Situation side, we again have Actions, along with other Conditions that affect the Targets we seek to control, and the Targets themselves (ACT).

The GAP-ACT Model provides useful insights into human behavior and performance as well as ideas regarding ways to improve performance in the workplace.  It also provides ideas and insights regarding performance problems and their solutions.  The GAP-ACT Model has been proven in practice for more than 30 years.

Fred Nickols is available to make presentations and conduct training related to The GAP-ACT Model.  He also provides consulting and coaching assistance in applying the model.  If you have any questions, you can use the Questions link at the bottom of this page to submit them to Fred.
