There are few reasons that contribute to its failure; some of them are related to user requirement analysis. Kimball et al.(2008) stated that requirement definition phase is paramount and impact almost every decision in DW project [9]. Most of failed DW projects execute poor requirement definition phase and some of them skip this phase [12]. They tend to focus on technical issues and not paid enough attention to requirement analysis [10]. Groggy method of conducting requirement definition analysis will lead to unstable design process [13] and poor communication between IT people and decision maker [3][10]. With lack of higher-level requirements vision [12], it is difficult to ensure the project will meet business goal.
