Oracle Fusion Procurement can be implemented in coexistence mode with a company's existing purchasing solution to provide additional functionality while avoiding risks. This allows sourcing, contracting, and analytics capabilities from Oracle Fusion Procurement to be used alongside the existing requisitioning and purchasing system. Benefits include improved visibility, sourcing capabilities, contract management, compliance, and analytics. The coexistence approach is a lower risk and cost option for beginning to leverage Oracle Fusion Procurement capabilities incrementally. Key considerations for implementation include integration points, data mapping, and approvals configuration between the new and existing systems.
