Although enterprise systems are gaining interests from both practitioners and researchers because of their potential linkagesto organizational and individual user’s productivity, there are few papers that investigate enterprise systems management andimplementation issues based on the end users’ perspective with the cross-cultural mechanisms. This issue is importantbecause currently the enterprise systems involve end-users with the different cultural backgrounds. Thus, this paper appliesenterprise systems adoption issue to the cross-cultural end user perspectives in Japan and the U.S. based on the personalinnovativeness in IT, intrinsic motivation, and the moderating effects of Hofstede’s cultural difference. Innovation diffusiontheory and self determination theory are the theoretical foundations for developing the model in this study. The paperproposes research model and the implications to the IS community.
