Nowadays a huge number of companies have implemented or plan to implement an ERP as their business management application. The use of an ERP, if done correctly, assures to the adopting company a competitive advantage. Nonetheless, the implementation process as well as the use phase, especially in the first months, presents several risks. This because an ERP strongly modifies the management of a company, the way in which the company works and its results. In addition, it has an impact on the allocation of power within a company and it involves a huge number of stakeholders. Consequently, the management of risks by a company before, during and after the implementation is of the utmost importance to achieve the expected profitability.
