Corporate planning is an essential component of a company's management system and serves as a basis for operational decision-making. However, recent literature increasingly criticizes traditional planning and budgeting approaches for failing to meet the current demands of corporate management: Planning in many companies is a lengthy and costly process that is often viewed by stakeholders more as a necessary evil than as a meaningful foundation for corporate governance. Modern, software-supported planning systems, such as the Business Planning and Simulation module from SAP AG, promise to provide a solution. This paper critically examines whether and how solutions to selected current problems or challenges in corporate planning can be implemented in SAP Business Planning and Simulation (BPS). For a specific corporate scenario, a suitable planning process is designed, prototypically implemented in the system, and finally evaluated critically.
