The essence of moving the organizations and companies toward the implementation of the Business Intelligence (BI) in the current competitive and complex atmosphere is not unfamiliar for any manager. By online analytic processing, the Business Intelligence analyzes the business data and creates a suitable context for making accurate and smart decisions. Neither as a product nor as a system but as the architecture and a new approach, the Business Intelligence has contained a set of analytic and applied programs. Since the managers have to identify the required infrastructures in creating the mentioned architecture before any applicable measures, the probable failures must be also considered and then solved by the managers. This study has been carried out in the Mellat Bank, meanwhile, the infrastructures for creating the BI has been identified and evaluated and subsequently, the findings has been discussed as well.
