Systems management: ERP and MES integration for operational innovation

Allowing data to circulate properly within the enterprise and breaking down information silos is one of the requirements for manufacturing companies to put value on the information they collect to increase efficiency, ensure traceability and fit into supply chains where the ability to integrate into highly automated environments is required.

One of the first steps in achieving this goal is the integration between ERP and MES, which is actually the first step in connecting the organizational part of the company with the production departments.

Once this integration is built correctly, the company will have created the basis for an information infrastructure that can then include all departments, processes and business procedures. But how to properly take this first step? Here are some considerations.

As is increasingly the case in IT projects of a certain complexity, the issue is not exclusively technological: the integration of ERP and MES can also be the ideal starting point for a change management process that, starting with the increased availability of information, enables an understanding of the benefits of a more data-driven business approach and facilitates the adoption of subsequent solutions with the aim of augmenting this integration and extending it to other functional contexts.

In addition, the definition of a common language for all business systems enables the approach to the back-to-standard paradigm, which will be increasingly pervasive in future products and services. This will enable the company to put itself in a position to adopt innovation more and more effectively and continuously.

The benefits of integrating ERP and MES

While in general terms ERP MES integration and the resulting unification of databases involves the elimination of information silos, defining in more detail what this entails for companies is not always so simple or straightforward. We recall below some of the most important benefits to use as a starting point for initiating a transformation project.

Improves data quality

Integrating ERP and MES creates an ecosystem in which data flow seamlessly, greatly improving data quality. Accuracy in production and inventory data enables a truer representation of business reality. Reducing errors, having more information available and being able to make deeper correlations increases both confidence in the data itself and its adoption as a decision-making tool.

Improved demand forecast

With integrated production and sales data, more sophisticated predictive analysis models can be applied to anticipate market demand. This makes it possible to both optimize production planning and minimize inventory costs, avoiding excess production, inventory or, conversely, supply shortages.

Improved process management

Integrating ERP and MES provides a unified view of business processes, from purchasing to delivery of the finished product. This allows both better visibility into business processes and the identification of possible room for improvement, which will allow the company to review its processes with a view to improvement and optimization.

Increased agility in order management

The synergy between ERP and MES optimizes order management and enables the use of advanced techniques such as Just in Time, in which materials are purchased and manufactured only when needed, thus reducing downtime and inventory costs. This approach improves business agility, enabling rapid and efficient response to customer demands, but to be successfully adopted requires an effective, high-performing, and integrated information infrastructure.

Traceability throughout the supply chain

Integrating ERP and MES improves product traceability throughout the supply chain. This is critical both from a regulatory perspective in many supply chains and for advanced product management, for example with recall campaigns or scheduled maintenance. Finally, it enables quality monitoring from suppliers to after-sales service.

How to integrate MES and ERP: key best practices

Effectively integrating MES and ERP systems is a multifaceted process that requires a structured and methodical approach. In order to carry it out effectively, we can refer to several frameworks of best practices. We recall here the fundamental and most widely used ones.

Define the requirements of integration

The first step in integrating MES and ERP is to clearly define the specific integration requirements. This means, for example, identifying the essential information that needs to be shared between the systems and having a thorough understanding of the operational needs of the end users. Accurate mapping of business processes will help define these needs.

Standardize formats, protocols, and databases

Standardization of data formats, communication protocols and database structures is essential for effective integration. The adoption of industry standards, or at least a shared and documented unified system for communication between devices and systems, and the use of common data formats can significantly reduce the complexity of integration and Facilitate future maintenance of systems.

Establish validation and synchronization mechanisms

To ensure data integrity and accuracy, resilient and effective validation and synchronization mechanisms must be established. These must be able to identify and resolve discrepancies in the data in a timely manner and ensure that the information is consistent and reliable.

Data governance

Data governance is critical to the effective integration of MES and ERP. Clearly defining the figures and systems responsible for different types of data, establishing policies for quality and security, and monitoring their use and sharing are essential steps for effective management.

Testing and continuous improvement

Finally, integration between MES and ERP does not end with the launch of the integrated system. A continuous process of testing, evaluation and improvement is necessary. Monitoring the performance of the integrated system and gathering feedback from users allows possible improvements to be identified and solutions to be adapted to business needs even as these change over time.

Back to standard and customization: finding the right balance

In the journey of integrating ERP and MES systems, companies must make another important choice: how much to adhere to industry standards, according to the back-to-standards approach we mentioned at the beginning, and how much to customize solutions to fit specific business needs.

Finding the right balance between these two approaches is an element of complexity that can make the difference between integration project success and failure. Adopting industry standards can significantly simplify the implementation and maintenance of systems, ensuring compatibility and facilitating integration with new technologies and software components. On the other hand, targeted customizations make it possible to adapt systems to the peculiarities of business processes, offering solutions that more closely reflect the characterizing operational needs of each company.

The key lies in carefully evaluating which aspects of systems can be standardized without compromising operational effectiveness and which require customization to preserve the unique and foundational characteristics of the production reality. It is essential that this assessment be guided by a deep understanding of business processes and strategic business objectives.

Finally, an iterative approach to design and implementation can allow for fine-tuning as experience and knowledge of the capabilities of the integrated systems are gained, thus ensuring that ERP and MES integration not only meets expectations, but exceeds them, driving innovation and continuous improvement within the enterprise.
