Enterprise resource planning (ERP) and product lifecycle management (PLM) have different business management perspectives—the first focuses on fulfilling physical orders with the respect of optimizing resource use whereas the second focuses on taking care of innovation processes by facilitating product definition collaboration. However, there is an intersection between the two systems. By empowering the consistent accessibility of one system's users to another system's data and processes, the integration between the two systems delivers benefits such as shorter time-to-market, lower manufacturing costs, and higher customer satisfaction.
The Need for ERP–PLM Integration in ETO Manufacturing
It is important for all manufacturers that have implemented ERP and PLM systems to build connections between the two software applications. For engineer-to-order (ETO) manufacturers (who design and manufacture products to the specific needs of the customer), the connection between ERP and PLM is even more important due to the specificity of the ETO sector.
Facilitating Engineering Changes
For ETO manufacturers, the probability of product and process changes is high. During the time between receiving customer requirements and delivering final products, changes happen (whether the customer modifies their requirements; design modifications are requested by the shop floor; or issues on the supplier's side result in using alternative parts). Quite often, a change initiated in one system (either ERP or PLM) will have a consequence in the other. For ETO manufacturers, the capability of efficiently capturing change requests and implementing change actions throughout the entire value chain (customer, manufacturer, and supplier) in a synchronized manner is one of the key success factors.
Reducing Rework and Scrap
Every manufacturer wants to reduce rework and scrap but ETO manufacturers dislike these costly activities more than the average manufacturer. In the ETO sector, the quantity of each product is usually small—unlike mass production manufacturing. This manufacturing process allows for a certain percentage of rework and scrap and costs are allocated to finished products without significant increase on unit price. For ETO companies to avoid catastrophic wastes in manufacturing processes, they have to make sure that the design department knows what can be made on the shop floor and that the production side always works on the up-to-date design specifications that reflect correct customer requirements.
