ERP vs MES – What are the differences?



When we talk about advanced IT systems that support the management of a manufacturing company, two acronyms always come up in the discussion: ERP and MES. These two types of systems are key tools for modern manufacturing companies, but what is their role, how do they differ, and do you need both? In this article, we will try to explain these concepts.


What is an ERP system?

ERP, which stands for Enterprise Resource Planning, is an enterprise resource planning system. It is an advanced tool that allows the integration of all the company’s business processes in one place. ERP systems cover various areas of enterprise operations, such as finance, HR, sales, production, logistics, and many more.


They are designed to provide effective management and control of company resources at all levels, improving information flow and facilitating decision-making.

What is a MES system?

On the other hand, MES, which stands for Manufacturing Execution System, is a production execution system. MES focuses on managing and monitoring production processes in real-time. It enables detailed tracking and analysis of production-related data, enabling the identification and elimination of inefficiencies, reduction of resource consumption, and increased production efficiency. MES operates at the operational level, directly on the production line, providing precise information necessary for managing production processes.

Collaboration between MES and ERP Systems

Although MES and ERP differ in their scope and purpose, both systems are often used together, creating a comprehensive solution for the enterprise. ERP provides strategic and tactical management tools at the enterprise level, while MES focuses on operational production management.

The collaboration of these two systems allows full integration of processes at both the strategic and operational levels. Production information collected by the MES system is transmitted to the ERP system, where it can be utilized for resource planning, demand forecasting, inventory management, and even pricing strategies.

On the other hand, the ERP system provides the MES with necessary information for effective production management, such as production plans, orders, product specifications, etc.

Do I Need Both Systems?

Whether you need both systems depends on the nature of your business. If you run a small enterprise with simple production processes, you may not require an advanced MES system. On the other hand, as your business grows and becomes more complex, integrating ERP and MES systems can bring significant benefits such as improved efficiency, cost reduction, and better control over the entire production process.

In summary, both ERP and MES systems play a crucial role in managing a modern manufacturing enterprise. Their integration allows the full utilization of production data, leading to better decisions, increased efficiency, and ultimately, better business outcomes.

Frequently Asked Questions

Are ERP and MES systems only for large enterprises?

No, ERP and MES systems are tailored to businesses of various sizes, from small firms to multinational corporations. Both systems are scalable, meaning they can be adjusted to the size and needs of your business. However, keep in mind that the effective implementation of these systems requires time, resources, and proper commitment, so the decision to implement them should be well-thought-out.

Can ERP and MES systems work independently?

Yes, ERP and MES systems can work independently, but they bring the greatest benefits when integrated. Through integration, data collected by the MES system can be utilized by the ERP system for resource management, forecasting, and planning, resulting in better business decisions.

Does every manufacturing company need an MES system?

Not every manufacturing company needs an MES system. These systems are most useful for companies with complex production processes that need to be managed and monitored in real-time. If your company doesn’t engage in complex production operations, you may not need an advanced MES system. However, even in such cases, an ERP system can bring many benefits in terms of resource management and planning.

Will it be the same for you? IPLAS will not solve the issues affecting low production efficiency for you, but it will precisely indicate their occurrence and duration. Through proper data analysis, you will be able to take actions targeted at localized problems and ultimately improve the efficiency of the production process.
