Examining Multiple Dimensions of Task-Technology Fit

摘要

Investigating the fit of an information technology to a user’s task, known as task-technology fit (TTF), is a frequent focus ofHCI/MIS research. In such research, “fit as moderation”, one of Venkatraman’s (1989) six conceptualizations of fit, iscommon. This conceptualization assumes two variables, e.g., task and technology, and an outcome variable. Task andtechnology, however, have multiple dimensions that should be considered when investigating fit. We examine three methodsHCI/MIS researchers have used for augmenting the fit as moderation conceptualization for multiple dimensions. We proposeand test a new method involving a single PLS model capturing the multiple dimensions of fit, which is more consistent withVenkatraman’s (1989) original conceptualization and statistical model for fit as moderation than those currently in theliterature. Our method as compared against one method in the literature, using a separate model for each dimension, works atleast as well.
