The Theory of Planned Behavior (TPB) has been widely applied in several disciplines to help better understand individual human behavior. For the past two decades, the TPB theory have been used in information systems research for providing the ability to predict a wide range of individual behaviors as they are exposed to different technologies and process in organizations and society. The TPB predictive power has been useful in better understanding issues driving individual human behavior as they interact with information technologies. Despite TPB’s impact to the information systems discipline, other researchers suggested additional elements to the basic model in order to better understand complex human behavior. In addition the TPB theory has seen addition of constructs to come up with new frameworks and models such as Technology Acceptance Model (TAM). Besides some criticisms of TPB and limitations it is still widely applied in several disciplines which include information systems.
