“What’s the difference between ERP and MES?” If you google this question, most articles will answer you: “Yes, they are two different systems and can be integrated.” Typically, this result leads to a false understanding as sometimes they are not independent. In this article, we will take a different perspective on this topic.
While ERP is a comprehensive suite of all functionalities that connect individuals in your organization to the same system, MES can sometimes be a small module within a holistic manufacturing-oriented ERP system. However, MES can also be an independent software application providing real-time information on the shop floor and allowing greater visibility and control over the production process. It collects data from various sources, such as machines, sensors, and workers, to optimize production and improve overall performance.
This is one of those hidden traps that need attention if you look for software for manufacturing and production. If you already have an ERP system and are only looking for a separate MES component, finding an independent MES to integrate makes sense.
However, suppose you would like to look for a manufacturing system with strengths and power in this field. In that case, the most appropriate ERPs comprise MES as an internal component without integration. For example, though SAP is an ERP system, it uses SAP ME as an MES system to integrate into the ERP. On the other hand, the Epicor ERP system has an MES module to collect data from operators/ workers as part of the software. It works out of the box without any integration.
When you purchase a system with MES as part of the ERP, it is time-saving in terms of general software management, upgrades and version controls, and customization. More often, separate software components require more skill sets for customization and managing customization. In some occasions, customizations may result in integration developments as well.
In conclusion, ERP and MES are critical tools for improving manufacturing operations. While ERP systems provide a broader solution that covers multiple business functions, MES systems are explicitly focused on the manufacturing process on the shop floor. The decision between the two depends on your organization’s specific needs, the customization level required, and budget constraints. By carefully evaluating these factors, you can select the right system that will help optimize your manufacturing operations and drive business success.
