Examining the relationship between IQ, DQ, usefulness, EoU, and task performance

Abstract

The World Wide Web (WWW) has become a premier source for locating information. However, much of Web’s content has not been verified for accuracy, relevance, or completeness. Using the IS success model, the technology acceptance model, and the unified theory of acceptance and use of technology models as a foundation, we empirically examined the impact of four constructs (perceived information quality, perceived design quality, perceived usefulness, and perceived ease of use) on task performance. We used Structural equation modeling to evaluate a new model for establishing a predictive relationship between the four constructs and task performance. Results indicate that there is a path relationship leading to accurate, relevant, and complete answers on the WWW. In the conclusion, we discuss the practical and theoretical implications of our research.
