The evolution of MES to MOM
There is a lot of confusion about the difference between a Manufacturing Execution System (MES) and Manufacturing Operations Management (MOM). Some think that the two are the same or that MES is a component of MOM, while others think that the two are totally different. What we have seen is a decades-long evolutionary development from MES to MOM.
The definition of SEM
The best way to understand the differences is to define them both. MES is an information system that facilitates the monitoring and control of the manufacturing process in the factory. The main role of an MES is to ensure that all manufacturing processes follow prescribed procedures so that the result is increased productivity and minimal waste.
Some of the activities and processes controlled by MES include customer orders, master schedules, Materials Resource Planning (MRP) systems, and other planning sources. Its main objective is to achieve operational efficiency in operations by reducing costs and ensuring maximum productivity.
MES came into being in the early 1980s and has had a huge impact on the manufacturing industry. It has been instrumental in collecting real-time data, giving actionable insights that aid in decision making.
The evolution of MES to MOM
MOM is a bit younger than MES and was created in the late 1990s to include solutions that have evolved to fit the same space. MOM provides a more complete product solution encompassing new dimensions of traceability, quality, production management, maintenance and covering ISA-95 level three architecture standards. It also provides enterprise manufacturing intelligence and the ability to implement a range of other advanced technologies such as Industry 4.0, making MOM an important part of the smart factory journey.
The ultimate goal of MOM systems is to facilitate closer integration of business planning functions and operations to increase agility. It collects data from shop floor machines, connected devices, and employees to help reduce costs, increase productivity, and deliver customers faster.
How is MOM different?
MOM is a software solution for managing end-to-end manufacturing processes to optimize planning, scheduling and operations while controlling quality and costs. This is a much more complete solution that has undoubtedly evolved from MES, providing full visibility into all manufacturing processes. The acronym “MOM” has replaced “MES” for various reasons, including the fact that the concept of “execution” does not correspond as well to process manufacturing as it does to discrete manufacturing.
A MOM will introduce unique approaches to the work environment by modeling the real world interactions between the factory and its operators. It creates an environment in which operators feel empowered and ready to fine-tune and streamline processes in order to perform optimally. Efficient use of MOM offers benefits to both plant management and operators.
Benefits of MOM for Plant Managers and Engineers
A MOM system helps managers achieve document compliance and ensures their products meet required specifications, reducing recalls to a minimum. Additionally, it will help improve visibility of critical data, increase productivity, reduce waste, lower production costs, enable better quality control, and improve management of production schedules and rates. without having to manage multiple systems from different vendors. The overall result is that the company’s brand value is protected by consistent quality.
MOM also helps managers visualize and see the process in action, thanks to the enhanced decision making and supply chain visibility it offers. Enable them to make better planning decisions and improve their chances of achieving customer satisfaction goals.
Whereas for factory engineers, the digital provision of work instructions will allow them to perform their tasks in a practical and economical way. This type of uninterrupted production is crucial in maximizing product quality and optimizing inventory levels, which will allow the plant to go lean.
Where MOM fits
A MOM solution provides the operational information a business needs about plant operations, but it needs to be integrated with information from the rest of the organization to get the most out of it. This is where an ERP system comes in.
An ERP provides inventory management, warehouse management, procurement, nomenclature, supply chain visibility, as well as back office capabilities such as financial and human resource management including businesses modern manufacturing needs.
When integrating ERP with MOM, manufacturers benefit from the precision of automation and data insight from both systems for full contextual decision making. This allows them to collect machine data and provide detailed reporting capabilities.
This ERP integration also enables companies to support end-to-end business processes through to manufacturing processes throughout the product lifecycle, including design engineering, supplier relationships, planning, scheduling, manufacturing execution, performance management, warehousing, shipping and customer relationship management. .
Manufacturers should ideally consider a MOM solution that meets world-class manufacturing standards and most importantly is fully integrated with their ERP, to leverage a single platform to monitor and improve plant performance. It will transform the way an organization manages people, equipment and processes to improve business performance and strategic results.
Should manufacturers implement MOM?
It is very clear that a manufacturer who implements better management of their industrial operations standards through MOM has a higher chance of success than a manufacturer who maintains traditional approaches.
To gain a competitive advantage, manufacturers must be agile enough to meet market demands at all levels of production without increasing costs or waste and without sacrificing efficiency. Adopting a MOM system can be the difference between success and failure.
