The Validity of an Extended Technology Acceptance Model (TAM) for Predicting Intranet/Portal Usage

by Chang, Paul Vin-Cent

Abstract (Summary)
This paper explores the validity of an extension of the Technology Acceptance Model (TAM) based upon additional constructs of social and facilitating factors taken from the Triandis model of choice. The extended model also incorporates age and user experience as external variables in predicting intranet/portal usage.

An intranet is defined as a network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. This study focuses on the intranet of an educational institution, the UNC Kenan-Flagler Business School. An online questionnaire was implemented to collect data concerning all variables in the extended TAM, including participants’ use of the UNC Kenan-Flagler intranet.

The research indicates that the constructs from the Triandis model increased the predictive results of the TAM, but only slightly. The external variables of age and experience also proved not to be strong indicators of intranet use.
