Unified Theory of Acceptance and Use of Technology (UTAUT) The purpose of formulating the Unified Theory of Acceptance and Use of Technology (UTAUT) had been to integrate the fragmented theory and research on individual acceptance of information technology into a unified theoretical model that captures the essential elements of eight previously established models (Venkatesh et al., 2003). To do so the eight specific models of the determinants of intention and usage of information technology were compared and conceptual and empirical similarities across these models were used to formulate UTAUT (Venkatesh et al., 2003). The eight discussed models were: IDT, TRA, TAM, TPB, C–TAM–TPB, Model of PC Utilization (MPCU), Motivational Model (MM), and the Social …show more content…

(2003) combined the views of user acceptance from eight previously established theoretical models to formulate four core determinants of key relationship and proposed a unified model called Unified Theory of Acceptance and Use of Technology (UTAUT) to predict user intentions to use IT. This model has been successfully employed in many technology adoption studies and has provided a useful tool for managers to assess the success of new IT introductions (Chang et al., 2007). Core Constructs Definitions Performance Expectancy “The degree to which an individual believes that using the system will help him or her to attain gains in job performance” (Venkatesh et al., 2003: 447). Effort Expectancy “The degree of ease associated with the use of the system” (Venkatesh et al., 2003: 450). Social Influence “The degree to which an individual perceives that important others believe he or she should use the new system” (Venkatesh et al., 2003: 451). Facilitating Conditions “The degree to which an Individual believes that an organizational and technical infrastructure exists to support use of the system” (Venkatesh et al., 2003:
