An Enhanced TAM Model for Measuring the Usability of Electronic Services

Abstract

The evaluation of electronic services (e-services) and determining the factors that affect users to adopt these services are needed. This study aims to shed light on the usability of e-services for the General Electricity Company in Libya using the Technology Acceptance Model (TAM). The TAM model was enhanced by adding some external variables that are suitable to the Libyan environment so that they can influence Libyan citizens to adopt e-services. The most common variables are trust, social influence, age, and education level, in addition to computer self-efficacy and web skills. The model has been validated by technology adoption experts. Based on the results of the study, a pilot website for the electronic services of the electricity company and a TAM model can be developed to measure the usability of the technology through its use and training.
