Why Every Factory Needs an Andon Board
Modern manufacturing depends on speed, accuracy, and seamless communication. Every minute of machine downtime, production delay, or quality issue directly impacts productivity, operating costs, and customer satisfaction. In a busy factory environment, relying on phone calls, paperwork, or verbal communication to report production problems often leads to delayed responses and extended downtime.
An Andon Board addresses this challenge by providing a centralized visual communication system that instantly displays production alerts, machine status, operator requests, maintenance notifications, and manufacturing KPIs. Instead of waiting for supervisors to identify problems manually, operators can trigger alerts immediately, allowing the right teams to respond without delay.
Originally introduced as part of the Toyota Production System (TPS), Andon Boards have evolved into intelligent digital platforms that integrate with PLCs, Industrial IoT (IIoT) devices, Manufacturing Execution Systems (MES), ERP software, SCADA systems, and cloud-based monitoring platforms. Today, they are an essential component of Industry 4.0 and smart factory initiatives, helping manufacturers improve visibility, reduce downtime, and optimize shop floor operations.
What is an Andon Board?
An Andon Board is a digital display system used in manufacturing to communicate production issues, machine conditions, maintenance requests, and operational performance in real time. It serves as a visual dashboard that enables operators, supervisors, maintenance personnel, and management to monitor the status of production lines from a single location.
Unlike traditional whiteboards or manually updated production charts, an Andon Board automatically displays live information collected from machines, PLCs, sensors, or production monitoring software.
A typical Andon Board displays:
- Machine status
- Production line status
- Active machine alerts
- Operator assistance requests
- Maintenance requests
- Downtime information
- Target vs actual production
- Overall Equipment Effectiveness (OEE)
- Shift performance
- Quality alerts
- Safety notifications
- Escalation status
This real-time visibility enables teams to detect and resolve problems before they affect overall production.
Why Every Factory Needs an Andon Board
Manufacturing environments operate under constant pressure to maximize production while minimizing downtime. Delayed communication can result in prolonged machine failures, quality defects, and missed delivery schedules.
An Andon Board helps manufacturers by:
- Providing instant production visibility
- Improving communication between departments
- Reducing machine downtime
- Accelerating maintenance response
- Increasing production efficiency
- Supporting Lean Manufacturing
- Enhancing workforce accountability
- Improving operational transparency
By making problems visible to everyone on the shop floor, Andon Boards encourage faster collaboration and continuous improvement.
How an Andon Board Works
Step 1: Issue Detection
Production issues may be detected by:
- Operators
- PLCs
- Industrial IoT sensors
- Vision inspection systems
- Machine controllers
- Safety devices
Step 2: Alert Generation
The system immediately generates alerts for:
- Machine breakdowns
- Material shortages
- Operator assistance
- Quality issues
- Maintenance requests
- Production delays
Step 3: Display on the Andon Board
The alert appears instantly on the digital Andon Board along with relevant production information such as:
- Machine ID
- Production line
- Alert category
- Time elapsed
- Responsible department
Step 4: Escalation
If the issue remains unresolved within a predefined period, automated escalation rules notify supervisors or senior management.
Step 5: Reporting
Every alert is recorded to support performance analysis, root cause investigation, and continuous improvement.
