Applying the task-technology fit model to WWW-based conceptualization and measurement

This research examines the application of the task-technology fit (TTF) model to World Wide Web (WWW) usage for electronic commerce (EC) purposes. Conducted from corporate buyers' perspective, this study assesses the extent to which Internet websites in general support the procurement process. The model suggests that a better fit between the tasks required during the procurement process and Internet Web sites' functionalities leads to a higher level of WWW usage, which then leads to an improved performance for users. All relevant constructs are discussed. Scales used to measure them are then developed. Data collected from 110 corporate buyers from over 100 organizations operating in a wide range of industries helped assess the validity and reliability of the scales needed to test the soundness of the model. This paper presents the results from instrument validation.
