MES–ERP Integration Playbook: Step-by-Step Implementation Framework is a practical guide for manufacturers looking to connect their Manufacturing Execution System (MES) and Enterprise Resource Planning (ERP) system into a single, integrated backbone. It explains why MES–ERP integration is essential for real-time visibility, accurate cost tracking, better traceability, and faster decision-making across the entire production lifecycle. The playbook walks through a structured implementation framework, from defining integration objectives and mapping business processes, to selecting the right architecture and designing robust data flows. It shows how to create a single source of truth that links customer orders, production execution, inventory, quality, and financial data. Clarify integration goals such as real-time production visibility, improved order-to-production lead times, and more accurate reporting. Map end-to-end workflows across sales, production, delivery, and invoicing, and define data ownership between MES and ERP. Evaluate integration architectures including point-to-point, middleware/ESB, and cloud iPaaS options based on scalability, security, and maintenance needs. Design a data exchange model for ERP → MES (orders, BOMs, specs, materials) and MES → ERP (production counts, scrap, downtime, quality results). Set communication standards with APIs, messaging, and data formats, and plan synchronisation policies for real-time and batch data. Configure, test, and pilot the integration before rolling it out across plants, supported by monitoring, alerts, and clear SOPs. Use dashboards and KPIs to continuously monitor performance, optimise data flows, and scale the integration to additional systems such as PLM, SCM, or CMMS. The playbook also highlights key roles and responsibilities across ERP, MES, IT, QA, and project management teams, and addresses common challenges like data mismatches, downtime, user resistance, and security risks. It is ideal for operations leaders, CIOs, digital transformation teams, and system integrators seeking a repeatable framework for successful MES–ERP integration.
