Checkpoint Systems is a multinational manufacturer and supplier of security solutions to the retail industry. It implemented a new SAP ERP system to consolidate operations across European subsidiaries after several acquisitions. The old systems were not Y2K compliant, did not support the euro currency, and made financial consolidation and reporting time-consuming. The new single-instance SAP system integrated various functions and subsidiaries. Challenges included aligning SAP terms with business terms, language and skills gaps during implementation, and cleaning up legacy master data for the new system. Lessons included not underestimating change management and the effort required for data cleansing.
