The selection of a new procure-to-pay (P2P) system requires a clear understanding of the specific needs and processes within the organization. By constructing a detailed list of transaction types and estimated processing times, supply management can ensure that the chosen P2P system is capable of handling the organization's workload efficiently and effectively. This step provides a concrete basis for evaluating potential systems and ensures that the selected system will meet the organization's specific requirements. References:
