Currently, Information Technology (IT) has assumed crucial role for achieving the efficient administration at both the strategic and the operational, providing business benefits that include reducing costs, increasing productivity, quality, flexibility and innovation. And one of the resources used is the implementation of a Warehouse Management System, called Warehouse Management System (WMS) software that receives the relevant information to the warehouse, generating responses for improved handling, storage, picking and shipping of products as the organization s needs. However, the implementation of a WMS system can be considered much more than a technology project that involves structural and behavioral changes, becoming a process of relatively high risk and complex. This study aims to identify and plan responses to the risks of implementing a new WMS in the warehouse of a large company in the cosmetics industry. The results confirmed many activities that must be managed in favor of non-commitment of the proposed objectives of the company, while knowing that the risk is somewhat uncertain as to its occurrence. Still, for future users of the WMS, to understand the inclusion of risk management in their deployment projects will bring greater likelihood of success, because as more becomes known risks and mitigating actions, more confidence and security firms will take into projects of this nature.
