When automation first began to be incorporated into manufacturing, the term Manufacturing Execution System (MES) was coined. MES was a tool for managing automated systems in a way that would allow manufacturing plants to run smoothly. It would achieve this by streamlining the processes, tracking them in production, and documenting the events automatically.
As time went on, companies found new ways of utilizing this new tool. With the growing demand for customized products, processes needed to be streamlined to work at higher efficiency, and production planning required optimization. For this, MES has proven to be a fantastic tool.
TL;DR
Manufacturing Execution System (MES) software tracks and documents shop-floor production, giving teams current information about jobs, materials and quality. ERP handles business planning, while MES supports manufacturing execution. ISA-95 provides models and terminology for information exchange between manufacturing control and enterprise functions; it is not a mandatory checklist of MES features. Modern MES systems offer capabilities such as manufacturing monitoring, inventory tracking and production analytics. Connecting MES with SkyPlanner APS adds scheduling based on production data and planner-defined priorities.
What is MES?
Manufacturing Execution System (MES) is software that tracks, documents and supports the execution of production on the shop floor. It collects data from operators, equipment and connected systems so teams can follow job progress, material use and quality.
MES and ERP have complementary roles. ERP supports business processes such as orders, purchasing and finance; MES provides more detailed information about manufacturing execution. Integration lets the two systems exchange production requirements and results.
MES is an integrated system of sensors and software which tracks the equipment, materials, and workers. It points out bottlenecks in the processes, helps schedule maintenance on equipment beforehand, and can also be used to provide customized instructions for workers and equipment based on the order. This helps keep processes streamlined and provides more reliable scheduling.
When MES was still in its infancy, it was quite loosely defined. Almost any method of tracking, documenting, or managing a process could be called a MES. This caused problems when operating the interfaces between MES and other systems.
ISA-95 defines models, terminology and information exchange for integrating manufacturing control with enterprise functions. Its integration scope is distinct from the historical MES function models developed by MESA. The list below is an overview of common MES functions, not a list of mandatory ISA-95 requirements:
MES Functions
- Data acquisition
- Quality control
- Scheduling
- Performance analysis
- Flow of products
- Genealogy and traceability
- Process management
- Resource management
- Personnel management
- Maintenance management

MES and ERP
When diving into the intricacies of industrial software, the debate of “MES vs ERP” frequently arises, and it’s easy to understand why.
MES and ERP often need clarification since it is hard to tell where one ends and the other begins. Both systems have some overlapping functions, and in some rudimentary cases, MES is not even required. Nevertheless, optimizing the running of a plant can prove difficult with ERP alone.
ERP (Enterprise Resource Planning) is a software system designed to run an entire business. It attempts to integrate and manage all aspects of a company’s business. ERP functions as a constantly updating database of events on all levels. This information can either manually or automatically be used to manage the resources needed to function optimally.
MES, on the other hand, does not extend outside the plant environment. The main task of this tool is to assess what resources (raw material, personnel, equipment) it has and how to utilize them to produce the ordered products optimally. This includes scheduling, equipment maintenance, inventory control, quality control, and documenting, among other things.
In an optimal situation, ERPs can make predictions based on the market projection for the future demand for certain products and relay this information to MES. MES can then adjust the production to suit the ERP’s needs. Manufacturing Execution System can allocate more resources to manufacture products in high demand optimally and automatically. In this way, ERP and MES can work seamlessly together.
Although an ERP can be used to manage even the most minor details of a manufacturing process, this task is often best left to Manufacturing Execution System. ERP software ideally handles what goes into the plant and what comes out, while MES handles everything happening inside the plant building.
Integrating MES and ERP systems isn’t just a matter of convenience—it’s a strategic move that can revolutionize a company’s operations. When these two powerhouse systems synchronize, they offer a harmonized view of manufacturing operations and business processes, ensuring decisions are based on comprehensive, real-time data. Such integration eliminates redundant tasks, bridges information gaps, and boosts overall efficiency.
MES ERP Integration brings a unified, coherent perspective, positioning businesses to be more agile, responsive, and competitive.
Benefits of using MES
Manufacturing Execution System collects production data from connected equipment, operators and other systems and makes it available to the team. Managers can use this information to identify delays and decide what to change. Records of production activity, material use and quality checks support quality and inventory control.
Optimizing lead time is vital for success, and an MES system helps by making job progress and delays visible. When an order changes, current production records help the team assess which operations remain and whether the change is feasible. The effect on lead time depends on available capacity, materials and the work already completed; customization is not disruption-free.
MES can relay production results to ERP, keeping business records aligned with shop-floor activity. ERP handles business-level processes, while MES supplies execution detail. They are complementary systems connected through integration.
Future applications of Manufacturing Execution System
Future MES applications may combine production records with analytics and AI to help teams identify patterns and respond to changes. Forecasting tools need to be evaluated against actual production data and the decisions they are intended to support.
AI-based scheduling already has a practical role alongside MES. In SkyPlanner APS, planners set priorities and constraints, and Arcturus calculates the schedule using production data, capacity and materials. Planners retain control through those rules and locks.
