Abstract

User commitment to a new information system is critical to its success. But what does this mean? One explanatory theory is the Technology Acceptance Model (TAM), which has gained wide recognition, but has also been criticized for its inability to account for temporal and contextual differences as well as its failure to consider how user commitment grows and changes with system use. This paper suggests that “user commitment” is not a binary proposition, but rather is better described as a range of values on a continuum. We propose such a model with at least four major components.
