Enterprise resource planning (ERP) systems play a vital role in today’s enterprises. They provide comprehensive standard solutions to support critical business processes. However, using a fully-fledged ERP system is often not practical for startups that depend on flexibility. Instead, young companies rely on lightweight solutions such as spreadsheets or individual business applications. While these solutions address their needs in the short run, successful companies will outgrow them when enhanced planning and reporting functionality is required. At this point, companies will be forced to implement ERP systems in complex migration projects. Nevertheless, even after ERP system implementation, it is not guaranteed that the systems will operate unchanged for an extended period. Changing market requirements force companies to react, resulting in costly process adjustments in ERP systems.
