Why computer users accept new systems

Abstract below from article in MIT Sloan Management Review, v42n3, Spring 2001. In a paper published in the December 2000 issue of Information Systems Research, Viswanath Venkatesh concludes that 6 variables significantly contribute to how users perceive the ease of use of specific systems over time. The 6 variables studied in actual corporate setting are: 1. computer self-efficacy, 2. facilitating conditions, 3. intrinsic motivation/computer playfulness, 4. emotion/level of computer anxiety, 5. objective usability, and 6. perceived enjoyment. I found the following observations to be the most salient for IAs: Immediately after training, the first four variables were found to be the only determinants of perceived ease of use; however, over time objective usability and enjoyment were found to influence user acceptance significantly. Most systems that arenít accepted fail because organizational, psychological and behavioral issues are not considered in their design.
