Understanding how users learn and become committed to a new information system helps developers design better implementation methods and academics identify the factors influencing that commitment. The authors propose the idea of a user continuum, in which 'learning' and 'use' increase commitment over time and are influenced by a variety of change events. We develop a model of commitment and examine the first stage. To test this model, the authors focused on the first phase of a major enterprise resource planning ERP implementation at a military installation, proposed a series of testable hypotheses, and used a participant survey with partial least squares analysis to measure the effects of user awareness, information transfer, and recognition on user realisation of the system. Pre-and post-training results showed model R2's of.77 and.57, respectively, and increases in the initial stage of user commitment was statistically significant.

This paper explores how performance expectations, anticipated learning curve, social influences, privacy concerns, and risk perceptions affect taxpayers' intention to use tax preparation software. We contribute to the extensive technology acceptance literature in three ways. First, we investigate whether perception and acceptance of tax software is different for professional accountants ('experts') compared to the general public ('novices'). Second, we assess the unified theory of acceptance and use of technology (UTAUT) model in the novel context of individual tax preparation and confirm the theory's ability to explain technology use outside the 'traditional' environment of business organisations. Third, we include constructs related to privacy and risk and test this extension of the technology acceptance model. Results indicate dissimilarities between the two subject groups and suggest the technology acceptance model may not be equally applicable to experts and novices.
