I have been involved in developing and extending the most widely-used theoretical models and frameworks on individual-level technology acceptance and use, with the collection of the papers being cited over 3,000 times. The most current of this is the unified theory of acceptance and use of technology (UTAUT), published in MIS Quarterly in 2003. UTAUT distills eight different models into 4 key predictors of technology adoption and incorporates 4 key contingencies that moderate the various relationships. Prior to this, Fred Davis and I published a paper on TAM 2 in Management Science in 2000 that extended TAM by examining the role of social influences and the determinants of perceived usefulness. Also, I published two related papers, building on the original TAM, in Information Systems Research in 2000 and Decision Sciences in 1996 that present the determinants of ease of use. The original two papers on TAM were from Fred Davis’ dissertation and published in 1989 in Management Science and MIS Quarterly. Fred Davis’ Management Science 1989 paper and our Decision Sciences 1996 paper are among the five most-cited papers in those two journals respectively.

I have several ongoing projects in this area. I am working on two different papers that are close to completion that focus on identifying fruitful future research directions in this domain. Work is currently underway in developing TAM 3, the 3^rd version of the technology acceptance model (TAM), co-authored with Hillol Bala, a PhD candidate at the University of Arkansas. Sandeep Goyal, a PhD student at the University of Arkansas, collaborators at various universities, and I are working on papers that challenge the assumptions of linearity in the various models. I am working with colleagues from various universities, including Likoebe Maruping and Hillol Bala, on research aimed at furthering our understanding of the key dependent variable of technology use.

An overview of the three major published theoretical models is shown here. The key published/accepted papers that present fundamental theoretical models and related findings are listed below:
