Perceived Usefulness, Ease of Use, and Usage of Information Technology: A Replication

TLDR

The studies aim to evaluate the psychometric properties of ease‑of‑use and usefulness scales and to examine how these constructs relate to system usage. Study 1 surveyed 118 respondents from 10 organizations about voice and electronic mail to assess convergent and discriminant validity of the ease‑of‑use and usefulness scales. The results replicate Fred Davis’s earlier findings on perceived usefulness, ease of use, and information technology usage.

Abstract

This paper presents the findings of two studies that replicate previous work by Fred Davis on the subject of perceived usefulness, ease of use, and usage of information technology. The two studies focus on evaluating the psychometric properties of the ease of use and usefulness scales, while examining the relationship between ease of use, usefulness, and system usage. Study 1 provides a strong assessment of the convergent validity of the two scales by examining heterogeneous user groups dealing with heterogeneous implementations of messaging technology. In addition, because one might expect users to share similar perspectives about voice and electronic mail, the study also represents a strong test of discriminant validity. In this study a total of 118 respondents from 10 different organizations were surveyed for their attitudes toward two messaging technologies: voice and electronic mail.
