Bombardier faced challenges from acquiring many companies, resulting in inefficient systems that did not communicate and caused low inventory visibility. They implemented an ERP system to address these issues. ERP implementation for a large global company like Bombardier is challenging due to converting data across locations and risks of errors. Benefits of ERP include reduced costs, improved visibility and decision-making, and improved operational efficiency. The strong point of Bombardier's Mirabel roll-out was that it allowed them to identify points that needed improvement to achieve goals.
