Wireless technology has truly changed people's way of doing today's business, both for individuals and companies. Applying wireless technology to the core information system like ERP system can bring ubiquitous benefits to companies. Meanwhile, the significance of integrating ERP system with business intelligence (BI) has come to more and more people's realization because it can help companies shorten the life cycle of data-to-knowledge, which is essential to decision-making. In order to capture the benefits of "mobility" and improve the timeliness of decision-making support, it is necessary and important for companies to incorporate the wireless application and BI integration to an ERP system. In this paper, we focus on how to apply the wireless technology to the ERP system and address the problem of integrating the BI as well. Based on the current ERP system, we proposed a model of Ubiquitous Enterprise Performance Management (U-EPM) system, which is expected not only to streamline the process of mobile business performance management, but also help companies to achieve better effectiveness and efficiency in doing business activities.
