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.


It provides a wide range of benefits for manufacturers. For example, integrating with ERP systems gives organizations a real-time view of production, making it possible to identify and address issues as they arise quickly.

In addition, it provides extensive data collection and analysis capabilities, allowing organizations to track performance and identify areas for improvement. Additionally, it can help manage quality control, ensuring that products meet the highest standards.

Finally, it can also provide valuable insights into maintenance needs, helping to reduce downtime and improve overall equipment efficiency. By leveraging the power of MES, manufacturers can experience significant improvements in productivity and quality.

Basic/MESA-11 Model Features

These features were defined by the Manufacturing Enterprise Solutions Association International (MESA) in 1997.

  1. Operations/detailed scheduling: Depending on the resource capacity and priority, scheduling, sequencing, and timing of the activities enhance the performance.
  2. Allocation of resources and status: Tracking and analyzing the resource status ( machines, labor, materials) using real-time data.
  3. Dispatching production units: Monitoring and managing the real-time production data flow for calculating the adjustments in production dispatching.
  4. Document control: Management of documents such as work instructions, standard operation procedures (SOP), drawings, batch records, etc.
  5. Labor management: Monitoring work schedules, employment qualifications, and authorizations to enhance the labor management system with fewer resources and time.
  6. Data collection and acquisition: Collect and track real-time information about materials, equipment, processes, and operations to make good decisions and enhance efficiency.
  7. Process management: Production process management from order release to final product manufacturing. Identifying the production bottlenecks that impact the quality of the production.
  8. Quality management: Monitoring of quality loopholes, management, and documentation
  9. Maintenance management: Using manufacturing execution systems data to determine equipment issues before they cause damage. Adjustment of machine and equipment schedules to increase production efficiency and decrease downtime.
  10. Product tracking and genealogy: Tracking product improvement and genealogy to make better decisions. Collecting product history to comply with industry standards or government regulations.
  11. Performance analysis: Performance analysis compares output results and goals to determine the process’s strengths and weaknesses.

MES Position as per ISA-95 Standard

Position of MES as per ISA - 95 Standard

MESA-11 focused only on the basic features of MES, but the International Society of Automation (ISA) included terminology and defined the activities between the control system and enterprise. So it established the ISA-95 standard in the 1990s.

The position of the MES as per ISA-95 standard is as follows.

  • Level 4 – ERP: Business planning and logistics
  • Level 3 – MES: Manufacturing operations management
  • Level 2 – Process control systems: Batch control
  • Level 1 – Process control systems: Continuous control
  • Level 0 – Process control systems: Discrete control

Advantages of Manufacturing Execution System

  • This process is helpful for industries including semiconductors, automotive, pharma companies, aerospace, etc.
  • It gathers valuable data on the production line. Hence you can upgrade your manufacturing process.
  • Allows you to manage your machines and employees in an easier way
  • It helps to eliminate human error in the manufacturing process.
  • It monitors manufacturing activities throughout the industry and links them in lead time.
  • It helps to control the manufacturing supply chain
  • Improves the quality of the product by providing real-time quality data checks. 
  • Eradicates valueless activities like paperwork
  • It helps to find the faults easily.
  • Supports complicated workflow process
  • Reduces manufacturing cycle time and data entry time
  • It helps to improve delivery performance and customer service.

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.

Difference Between MES and ERP

MES stands for Manufacturing Execution System, while ERP stands for Enterprise Resource Planning. MES is focused on the execution of manufacturing operations, while ERP is a broader system that incorporates financials, HR, and other aspects of the business.

MES systems are typically used to manage production processes and track resources (e.g., machines, tools, people). In contrast, ERP systems include modules that can provide these same functionalities and cover other aspects of the business, such as sales and marketing, accounting, and purchasing.

Difference between ERP and MES

The significant difference is that Enterprise Resource Planning (ERP) creates and manages your basic schedules for production, material use, delivery, and shipping and helps collect information for your business.

ERP system is a mixture of many modules like production, supply chain, order processing, inventory management, customer relationship management, and human resource management. Usually, it concentrates on working within the time limit of months, weeks, and days.

It helps monitor and track your shop floor manufacturing process and allows you to generate real-time reports on production plant activities.
