What is MES?
A Manufacturing Execution System serves as the central control hub of a manufacturing operation, overseeing and coordinating every aspect of the production process.
It acts as a diligent manager, monitoring and managing production activities, inventory levels, equipment utilization, and workforce allocation to ensure optimal efficiency and productivity.
It collects data from the production line and other sources and provides it to operators, managers, and planners to make better product production decisions.
It can help companies improve quality, efficiency, and throughput. It can also help them respond quickly to customer demands and changes in market conditions.
For example, if there is a sudden increase in customer demand for a product, the system can help the company quickly ramp up production to meet the demand.
Conversely, if there is a drop in demand, the system can help the company reduce production to avoid excess inventory. In this way, it can help companies be more agile and responsive to changes in market conditions.

Manufacturing Execution System History
Around the 1970s, some manufacturing industries started using software applications to automate their accounts.
Time files and these applications improved and provided particular features for standard inventory management.
In the early 1980s, manufacturing requirements planning (MRP) came with material planning, control, and monitoring.
In the 1990s, the system improved, and the manufacturing execution system came into the picture.
Best Practices for Implementation
There is no one-size-fits-all answer to this question, as the best practices for MES implementation will vary depending on the specific needs of your business. However, some tips to consider include:
- Define clear rules to implement the project.
- Defining the rules involves the production, quality, execution, maintenance, and IT department members throughout the rule-making process.
- Involve stakeholders during the implementation process.
- Set an achievable schedule for implementation and testing.
- Originate a detailed MES system per user requirements with a distance between the control and enterprise resource planning (ERP) layers.
- Perform risk management for design, development, and deployment stages.
- Determine the merging points between the layers to comprise your architecture. For example, MES stands for execution, and ERP stands for planning. So ERP directs the MES on what to make, and MES tells what was made and where it went.
- Combine the MES software with other production control systems.
Common Mistakes During Implementation
- Not giving attention to the connection of MES requirements with particular business drivers.
- Skipping the steps while getting into the details of master data ownership, the interface points to the control system in the designing stage.
- Improper determination of user requirements.
- Not reviewing the design before implementation. If you review the design before only, you can make the changes before the implementation.
- Improper establishment of the existing operating system. If you do not establish the current operating system, it is not easy to compare and find out the benefits of the MES system.
- Not evaluating the system after implementation. Before switching over entirely to the new system, It is necessary to test the system, even if you implement it as per the plan.
