Chapter 1: What Is MES? — Concept, History, and Its Role in Factory DX

1.1　Definition of MES

MES (Manufacturing Execution System) is “a system that receives the production plan drawn up in the ERP, translates and distributes it into concrete manufacturing instructions for the plant’s lines and equipment, and collects on-site performance results to feed back into the ERP.” While the ERP handles “what to make, how many, and by when (planning),” the MES manages “who, on which equipment, using which material lot, started and finished at what time (execution).”

MES in One Sentence

Standing between ERP planning and SCADA/PLC shop-floor control, MES is the factory’s “nervous system,” responsible for “manufacturing instructions, performance data collection, quality management, and traceability.” Level 3 (Manufacturing Operations Management) of the ISA-95 (ANSI/ISA-95) international standard is the domain covered by MES.

1.2　The ISA-95 Model: The Scope of MES

ISA-95 (the international standard for enterprise-control system integration for manufacturing companies and control systems) classifies manufacturing information systems into five levels.

Level	Role / Function	Key Systems	Primary Management Time Horizon
Level 4 (Business Planning Layer)	Order receipt, procurement, production planning, cost management, finance	ERP (SAP S/4HANA, etc.)	Monthly / weekly / daily
Level 3 (Manufacturing Execution Layer)	Work instructions, performance data collection, quality, traceability	MES / MOM (the subject of this article)	Shift / hour / minute
Level 2 (Supervisory Control Layer)	Process monitoring, alarm management, data collection	SCADA / DCS / HMI	Seconds / minutes
Level 1 (Field Control Layer)	Automatic control and sequence control of machinery and equipment	PLC / DCS / CNC	Milliseconds / seconds
Level 0 (Field Device Layer)	Physical production, measurement, conveyance	Sensors, actuators, robots	Continuous (real time)

1.3　What Happens in a World Without MES

We are often asked, “If we have ERP, isn’t MES unnecessary?” In reality, however, factories without an MES chronically suffer from the following problems.

Problem 1: The Shop Floor Is a Black Box

Even after production plans are entered into the ERP, it is impossible to grasp in real time “which line is producing which product right now, how much progress has been made, and why there is a delay.” Plant managers have no means other than “walking the floor to check” or “calling to ask,” which delays the discovery of problems.

Problem 2: Traceability Cannot Be Achieved

Bidirectional tracking questions such as “which lot of material was used in this product?” and “which products used this material lot?” become incomplete when relying on manual records. When a recall occurs in the food, pharmaceutical, or automotive parts industries, it can take days to weeks to identify the scope of impact. With MES, this can be completed in minutes.

Problem 3: Quality Problems Are Discovered Late

When in-process quality data (dimensions, weight, temperature, pressure) is managed via handwritten records or Excel, anomalies are only discovered “at the next inspection point” or “after a defective product has become a finished good.” With MES’s SPC (Statistical Process Control) integration, abnormal trends in process parameters can be detected in real time at the earliest stage of occurrence.

Problem 4: OEE Cannot Be Measured or Improved

Unless equipment “operating time, downtime, downtime causes, production quantity, defect quantity, and cycle time” are collected, OEE (Overall Equipment Effectiveness) cannot be calculated. When “which equipment or loss factors need improvement” cannot be seen as numbers, manufacturing improvement activities remain dependent on the “intuition” of veteran staff.

Problem 5: ERP Planning Accuracy Does Not Improve

ERP’s MRP calculations depend on parameters such as “equipment capacity, actual cycle time, changeover time, and yield rate.” If these are not actually measured by MES, the system continues to rely on inaccurate default values. Only through performance feedback from MES does ERP’s planning accuracy begin to approach reality.

1.4　The Division of Roles Among MES, ERP, PLM, and SCADA

Perspective	ERP	MES	PLM	SCADA / PLC
Main question	What, how many, and by when?	Who, on which equipment, when, and in how many minutes?	How is it designed and how is it made? (design knowledge)	How is the equipment operating right now?
Managed scope	Orders, inventory, procurement, cost, finance	Work instructions, performance, quality, traceability	BOM, drawings, processes, change management	Voltage, temperature, pressure, rotation speed
Time horizon	Monthly to daily	Shift to minutes	Product life cycle (years to a decade)	Milliseconds to seconds
Quality information	Defect count and cost (aggregated)	Defect causes, SPC, in-process records	Design quality, inspection plans (QM)	Sensor alarms, threshold management
BOM	Receiving and executing the manufacturing BOM (MBOM)	Expanding the BOM into process instructions	Source of EBOM, MBOM, and BOP definitions	Equipment recipes and parameters
Traceability	Lot numbers, inventory movement (aggregated)	Detailed records from material lot to process to finished product	Design change history (Design Traceability)	Equipment status logs (continuous)

1.5　The Relationship Between MES, Digital Factory, and Digital Thread

Modern MES has evolved beyond its ISA-95 Level 3 role to become the foundation for realizing the Digital Factory and Digital Thread.

• Digital Thread with PLM: The BOP (Bill of Process) and work instructions defined in PLM are deployed into MES. The cycle in which, once a design change (ECO) is approved, MES’s work procedures and BOM are automatically updated is the core of the Digital Thread.

• Integration with Digital Twin: Combining the real-time production performance and equipment operating data collected by MES with PLM’s design data realizes a “Digital Twin of the manufacturing process” (a digital replica of the operating plant).

• Integration with IIoT and edge computing: Modern MES connects with edge devices and AI analytics through industrial IoT protocols such as OPC-UA and MQTT. Integration with predictive maintenance for equipment and AI-based visual inspection is also progressing.

1.6　How to Think About MES Return on Investment (ROI)

• OEE improvement: A 10-to-15-point improvement in OEE has been reported as a result of MES adoption (global average OEE: around 65% → 75-80%). This can be equivalent to hundreds of millions of yen in additional production capacity per line per year.

• Reduction in defect costs: Early detection of in-process defects (via SPC) has led to cases where the cost of defective product outflow and rework is reduced by 20-40%.

• Traceability response cost: Recall investigations that used to take days before MES are completed in minutes, dramatically reducing the labor required for audits and recall response.

• Paperless operations: Eliminating paper forms and handwritten records reduces recording effort, eliminates transcription errors, and reduces storage costs. Typically, 1-2 hours per worker per day of recording effort is eliminated.

Chapter 2: Core MES Functions — A Detailed Look at the MESA-11 Framework

The functional taxonomy of MES is organized around the “MESA-11” (11 functional areas) defined by MESA International (the Manufacturing Enterprise Solutions Association). Below, each function’s definition, practical significance, and contrast with a world without MES are explained in detail.

2.1　Work Order Management

Receives manufacturing orders from ERP and converts, issues, and tracks them as concrete work instructions at the process, equipment, and worker level on the shop floor. It instructs the floor on “which line, which product, using which materials, and starting when.”

• Electronic work instructions (e-Job Card): Paper “work instructions” are digitized and presented to workers on tablets and touch panels. Work procedures, drawings, and videos can be linked and presented.

• Real-time changes to work instructions: Emergency interruptions, priority changes, and process switches due to material shortages are reflected in real time, and the screen on the floor is updated instantly.

• Automatic recording of completion results: The time, quantity, and material lots used when a worker presses the “Complete” button are automatically recorded and sent back to ERP as performance results.

2.2　Production Scheduling and Dispatching (APS)

Optimizes “which work is executed on which equipment and in what order.” Rather than simple FIFO (first in, first out), finite capacity scheduling that considers equipment capacity, changeover time, material constraints, and priority is at the core of modern APS.

• Finite capacity scheduling: Generates achievable plans premised on the actual capacity of equipment (e.g., maximum 8 hours of operation per day, 30-minute changeover). While ERP’s MRP generates an “ideal plan” premised on infinite capacity, APS generates a “realistic plan.”

• Changeover optimization: Automatically calculates a production sequence that minimizes the number and duration of changeovers for color changes, mold changes, and material switches. Reducing changeover time is one of the biggest factors in improving OEE.

• Multi-scenario simulation: Multiple scenarios such as “What if Equipment A breaks down today?” or “What if an urgent order comes in?” can be created and compared, allowing selection of the response with the smallest impact.

2.3　Quality Management

MES centrally manages in-process quality inspection instructions, results recording, pass/fail determination, SPC, nonconforming product management, and corrective action (CAPA). Integration with PLM’s QM (SAP QM, Opcenter Quality, etc.) achieves “alignment between design quality and manufacturing quality.”

• SPC (Statistical Process Control): Plots measured values in real time on control charts (X-bar/R charts, np charts, etc.), automatically issuing alerts for early detection of process anomalies and control limit deviations.

• Nonconforming material management (NCM): Records the occurrence of defective products and manages them by status such as “quarantine, awaiting inspection, scrap, or special release.” By linking with MES’s manufacturing traceability, the scope of impact within the same lot can be identified instantly.

• CAPA (Corrective and Preventive Action) management: Digitizes and tracks everything from root-cause analysis of defects and registration of recurrence-prevention measures through to confirmation of effectiveness.

2.4　Equipment Management and OEE

Collects and displays equipment operating status (running, stopped, in changeover, under maintenance) in real time, and calculates OEE (Overall Equipment Effectiveness).

• OEE = Availability × Performance × Quality Rate

• Downtime analysis: Classifies and aggregates downtime causes such as planned stoppages, breakdown stoppages, waiting for materials, quality-related stoppages, and changeovers, visualizing “where the biggest OEE losses are.” Used to prioritize improvement activities.

• Predictive maintenance (PdM) integration: Integration with PdM platforms that continuously collect equipment vibration, temperature, and current values via MES and use AI algorithms to detect “signs of failure” is advancing.

2.5　Product Traceability

Completely records, at the product serial number/manufacturing lot level, “which material lot was used, on which equipment, by whom, when, and by which procedure it was used/manufactured.” This is an “electronic manufacturing record” across the entire product life cycle.

• Forward trace: Tracks “into which finished products was this material lot (raw material Lot #A001) ultimately incorporated?” Used to identify “affected products” at the time of a recall.

• Backward trace: Tracks “which materials were used in this finished product (serial #SN-12345)?” Used to investigate the cause of customer complaints.

• Electronic Batch Record (EBR): MES electronically generates and maintains the “complete record of a manufacturing batch” required under pharmaceutical and food GMP requirements.

2.6　Labor Management

Manages workers’ “skill certification status, work performance, productivity, and overtime.” Linked with a skills matrix (definitions of the skills and qualifications required for specific tasks), it enables control of “processes that can only be performed by certified workers.”

2.7　Document Management and Electronic Work Instructions

Presents work instructions (SOPs), drawings, quality standards, and videos “in the right process, at the right time, on the screen of the right worker.” The latest work instructions, version-controlled in PLM, are automatically distributed to the shop floor via MES. Integration with PLM is a particularly important function here.

2.8　Material Tracking and Lot Management

Tracks the movement of materials, work-in-process, and finished goods in the manufacturing process. By recording “which material lot was consumed, when, at which process, and in what quantity,” it provides an accurate grasp of inventory and a foundation for traceability.

2.9　Performance Analysis

Visualizes KPIs such as OEE, production achievement rate, defect rate, and cycle time in real time and historically. Includes manufacturing dashboards, anomaly alerts, and automatic generation of standard reports.

2.10　Process Management

Collects actual values of process parameters (set temperature, pressure, speed, mixing ratio) and monitors deviations from specified values (SOP). Alert issuance and automatic interlock (process stop) functions when deviations from specified values occur ensure safety and quality.

2.11　Maintenance Management

Manages PM (preventive maintenance) schedules, failure records, and the issuance of repair instructions for equipment through MES. By linking MES’s production schedule with the maintenance calendar, it becomes possible to minimize unplanned stoppages and optimally allocate maintenance personnel. Integration with SAP PM enables integrated management of the equipment ledger and maintenance costs on the ERP side.

5.6　SCADA / PLC Integration

MES-SCADA/PLC integration determines the “volume, speed, and reliability” of data collection. The quality of integration with shop-floor control devices defines MES’s actual data collection foundation.

Chapter 6: Selection Matrix and Implementation Decisions by Industry and Use Case

6.1　Recommended Products by Industry

Industry / Product Characteristics	Top Choice	Runner-Up	Main Rationale for Selection
Automotive / motorcycle (OEM/Tier 1)	Opcenter	DELMIA Apriso	Comprehensive strength in APS, multi-site quality management, and SAP integration. Opcenter is the obvious choice for plants with a lot of Siemens equipment
Pharmaceuticals (prescription drugs / biologics)	DELMIA Apriso	Opcenter	The most extensive track record in GMP EBR, electronic signatures, and FDA inspection compliance. A signature industry for Apriso
Semiconductors / electronic components	Opcenter (formerly Camstar)	(others not recommended)	Opcenter, which inherits the former Camstar, is the industry standard for semiconductor-focused MES functionality
Food & beverage (major domestic players)	DELMIA Apriso	SAP DM	Allergen management, lot tracking, formulation management, global deployment. SAP DM is also a strong option in an SAP environment
Food & beverage (North America-centered)	FactoryTalk	DELMIA Apriso	North American CPG often runs Rockwell Allen-Bradley environments, where native integration with FactoryTalk is a strength
Chemicals / petroleum / process manufacturing	SAP DM	FactoryTalk	Recipe management via SAP PP-PI integration. FactoryTalk on Allen-Bradley DCS is also a strong option
Industrial equipment / machine tools	Opcenter	FactoryTalk	Integration with APS and Siemens NC machine tools. FactoryTalk if operating in an Allen-Bradley PLC environment
Medical devices	Opcenter (formerly Camstar)	DELMIA Apriso	Management of FDA DHF, electronic signatures, and Device History Records
SAP integration as top priority / simple MES	SAP DM	Opcenter	Seamlessly achieves BOM/QM/PM integration in a unified manner with SAP ERP. For cases where MES functional complexity is unnecessary

6.2　Decision Flow by Deployment Environment and Challenge

• Step 1: Is the shop-floor PLC/SCADA primarily Siemens (S7/TIA Portal)? → If yes, Opcenter is the first candidate. Control-MES-ERP can be integrated consistently through Siemens Xcelerator.

• Step 2: Is the shop-floor PLC/SCADA primarily Rockwell Allen-Bradley? → If yes, FactoryTalk is the first candidate. It offers the lowest-cost native integration for OEE visualization and dispatching.

• Step 3: Do you want to integrate and manage multiple global plants under a single MES? → If yes, DELMIA Apriso is the first candidate. Centralized management and global distribution of process standards via the GBM is the most mature.

• Step 4: Have you already implemented SAP S/4HANA and want native PP/QM/PM integration? → Consider SAP DM. However, if advanced quality management or scheduling is needed, a combination with a dedicated MES is recommended.

• Step 5: Is GMP/EBR/FDA compliance the top priority in pharmaceuticals or medical devices? → Choose Opcenter (formerly Camstar) or DELMIA Apriso.

• Step 6: Is advanced APS (finite capacity scheduling, changeover optimization) the top-priority challenge? → Opcenter APS (formerly Preactor) is strongly recommended.

Choosing Between a Dedicated MES and SAP DM

Cases where SAP DM (SAP Digital Manufacturing) is the best fit: · You use SAP S/4HANA as your core ERP and want to minimize ME-ERP integration costs · Simple manufacturing order management, results collection, and basic quality integration satisfy your requirements · In process manufacturing (chemicals, food), integration with SAP PP-PI/recipe management is needed Cases where a dedicated MES (Opcenter/Apriso/FactoryTalk) is required: · Advanced APS (finite capacity scheduling, changeover optimization) is needed · Complex in-process quality management, SPC, CAPA, and EBR are needed · Industry-specific functionality for semiconductors, pharmaceuticals, etc. is needed · Deep native integration with a specific PLC (Siemens, Rockwell) is needed The realistic solution for many large manufacturers: a two-tier structure of “dedicated MES (Level 3 execution) + SAP (Level 4 business management).” Hybrid configurations that place SAP DM as an intermediate ERP integration layer (Level 3.5) are also increasing.

6.3　Typical MES Implementation Failure Patterns

• Failure 1: Scope that is too broad for a single rollout: Attempting to implement all MESA-11 functions at once. Start with the “most painful challenge” (e.g., traceability or OEE visualization) and adopt a phased rollout strategy that expands step by step.

• Failure 2: Underestimating equipment interface costs: 30-40% of total MES implementation cost is “the cost of building interfaces with PLCs and equipment.” Always conduct a site survey (equipment inventory, communication protocol survey) in advance.

• Failure 3: Undefined scope of PLC data collection: If “what MES collects from PLCs, at what frequency, and at what precision” is not defined at the design stage, frequent specification changes will occur later. Define the OPC-UA tag list and data sampling interval in detail in advance.

• Failure 4: Lack of change management for shop-floor workers: Without a behavioral shift toward “entering results on a terminal” and “checking procedures on a screen instead of a paper form,” data quality cannot be assured and the value of MES becomes zero.

• Failure 5: Underestimating the complexity of SAP integration: Real-time bidirectional synchronization between “SAP production orders and MES work instructions” requires significant design and testing effort. Agreeing in advance on the boundary design between SAP and MES (which system manages what) is essential.
