The advance of information technology (IT) in recent years has allowed companies to execute operations that previously were unimaginable. The adoption of integrated systems has been common in large and medium- sized companies world-wide as they have sought to integrate all aspects of their business, such as planning, purchasing, sales, manufacturing, finance, control, and supply, with the objective of achieving greater agility and the power to make decisions. To take care of this necessity, ERP systems have emerged, which offer the potential for the fast development of these integrated systems. However, it is essential that the implementation of these projects is successful since they impact the company as a whole. Hence, effective risk management in projects of this nature is one of the critical factors of their success. However, appropriate risk management is seldom practiced in the majority of these projects. This work has the objective of developing a list of probable risks that may affect the success of these projects, with the intention of minimizing their impact, and assisting future implementations to plan properly to avoid these risks.
