How Integration Works

ERP and PLM integration typically involves connecting the two systems through an interface that allows them to exchange data. This interface can be custom-built or provided by a third-party vendor. The specific data that is exchanged will vary depending on the needs of the organization, but it typically includes:

• Bill of Materials (BOM): Transfers BOM data from PLM to ERP for manufacturing planning and costing.
• Engineering Changes: Transmits engineering change orders (ECOs) from PLM to ERP to update product specifications and manufacturing processes.
• Product Data: Shares product data, such as part numbers, descriptions, and specifications, between the two systems.
• Inventory Data: Provides real-time visibility into inventory levels in ERP to inform product development decisions in PLM.

The integration can be one-way or two-way, depending on the level of integration required. A one-way integration typically involves transferring data from PLM to ERP, while a two-way integration allows for data to be exchanged in both directions.

Examples of ERP and PLM Integration Scenarios

To better illustrate the benefits of ERP and PLM integration, let’s consider a few examples:

Scenario 1: Engineering Change Management

Imagine an engineering team identifies a flaw in a product design that requires a change. In a non-integrated environment, the engineers would need to manually communicate the change to the manufacturing team, who would then need to update the BOM in the ERP system. This process can be time-consuming and prone to errors.

With integrated ERP and PLM systems, the engineers can initiate an engineering change order (ECO) in the PLM system. This ECO is then automatically transmitted to the ERP system, where the BOM is updated accordingly. The manufacturing team is immediately notified of the change, ensuring that they are using the latest product specifications. This streamlined process reduces errors, improves efficiency, and speeds up the time to market.

Scenario 2: New Product Introduction (NPI)

Introducing a new product to the market requires careful coordination between engineering, manufacturing, and sales. In a non-integrated environment, these teams may operate in silos, leading to delays and miscommunication.

With integrated ERP and PLM systems, the product development process is streamlined. As the engineering team designs the new product in the PLM system, the manufacturing team can access the BOM and other product data in the ERP system. This allows them to plan for manufacturing and procurement early in the development process. The sales team can also access product information in the ERP system to prepare for the product launch. This collaborative approach ensures a smooth and efficient NPI process.

Scenario 3: Supply Chain Optimization

Managing the supply chain effectively requires real-time visibility into inventory levels and demand forecasts. In a non-integrated environment, this information may be difficult to obtain, leading to stockouts or excess inventory.

With integrated ERP and PLM systems, the supply chain can be optimized. The ERP system provides real-time visibility into inventory levels and demand forecasts. This information can be used by the engineering team in the PLM system to design products that are easier to manufacture and source. The PLM system can also provide information on the availability of materials and components, allowing the procurement team in the ERP system to make informed purchasing decisions. This integrated approach ensures a smooth and efficient supply chain.
