Abstract
The purpose of this paper is to analyze whether the consensus building between the information system sector and the user sector influences the satisfaction rating of the user sector. If the consensus building between the information system sector and the use sector doesn't function well, a final IT effect of the user sector cannot be expected. The WEB questionnaire data for about 10,000 people of Kanto-Kinki region executed in February 2010 was used for the analysis. I used the level of the hearing from user sector when the new information system introduced as the consensus index. It turns out that the enterprise with an insufficient consensus building had the negative effects on the IT satisfaction rating and the job satisfaction rating.
