Power, perception and performance: from usability engineering to technology acceptance with the P3 model of user response

Understanding the dynamics of technology acceptance by intended users has proved a very difficult problem but it remains a key question for developers, implementers and system procurers. In the present paper we draw on existing findings from two independent research traditions (HCI and MIS) to propose a unified model of the factors that seem to be important determinants of use. This model is represented in conceptual terms and it is proposed as an enabling framework for human factors practitioners to apply the basic principles of acceptance throughout the development and implementation process
