The business case for ERP implementation is a comprehensive document that outlines the reason for investing in enterprise resource planning (ERP). It describes the potential benefits of the implementation, identifies possible risks and costs associated with the project, and includes a plan of action for how the organization will maximize its return on investment. The business case also serves as a guide for decision makers by offering a detailed description of the problem, an analysis of alternative solutions, and recommendations for the best course of action. It’s essential that all stakeholders in the ERP process are involved in producing the business case, so that they understand and agree with its outcomes. In short, the business case will provide the justification needed to ensure successful ERP implementation.
