multiERP

MultiERP refers to the use of more than one ERP system within a single organization. This situation often arises from mergers and acquisitions, a multinational footprint with regional ERP deployments, or business units that require specialized functionality. In a multiERP environment, each ERP may serve different teams or regions while efforts are made to enable cross-system coordination through integration, governance, and data management.

Architectures commonly used in multiERP include coexistence, federated, and hybrid models. In the coexistence model, data and processes are bridged across ERP systems using middleware or integration platforms to support cross-system workflows and analytics. In the federated model, each unit retains its ERP as the system of record, but a shared data layer and reporting layer deliver consolidated visibility. Hybrid approaches combine elements of both, balancing local autonomy with centralized oversight.

Key challenges involve data harmonization and master data management, process alignment, data quality issues, and duplicate records. Additional considerations include regulatory and security compliance, higher total cost of ownership, more complex IT governance, and potential user adoption barriers. Benefits can include resilience through redundancy, local flexibility for regulatory or operational requirements, smoother integration of acquisitions, and the ability to optimize regional processes while preserving global visibility via analytics.

Implementation considerations for multiERP programs include establishing an enterprise architecture and data governance framework, selecting appropriate integration technologies (such as iPaaS, APIs, and data services), and planning a phased roadmap for integration, data cleansing, and potential consolidation. Success often depends on clear ownership, standardized data models, and effective change management.
