The core concept is to treat the Kanban as an "output channel for on-site data" rather than just a standalone large screen. First, clearly define what data needs to be displayed and where the data originates before discussing hardware and installation. The implementation path differs significantly depending on whether there is system support or not.
1. Organize data sources first, do not rush to purchase screens
Without a system, Kanbans often rely on manual data entry or periodic card replacements. ESD monitoring data requires team leaders to measure it with instruments and then write it down manually, leading to delays and omissions. With a system, data from electrostatic field testers, access-controlled body resistance testers, and ionizer status can automatically feed into the Kanban. The first step of implementation is to clearly list ESD monitoring points, the number of workstations, and the indicators to be displayed, such as body resistance pass rates, grounding impedance status, and alarm workstation IDs.
2. Determine Kanban hierarchy and deployment locations
Typically, there are three levels: an overview Kanban at the line entrance showing overall line ESD compliance rates and alarm summaries; small screens in the workstation area displaying real-time status and operation prompts for that specific station; and displays in maintenance or changeover areas showing historical alarm records. A solution without a system usually only implements the first level using Excel imports. A solution with a system allows all three levels to link, with alarms automatically pushed to the corresponding workstations.
3. Plan network cabling and power supply in advance
ESD monitoring terminals mostly use RS485 or Ethernet protocols. If the Kanban uses network protocols (such as MQTT integration), network cables must be laid or WiFi configured in advance. Power over Ethernet (POE) is more convenient. If this step is not done well, adding screens later will require re-construction. Suppose a hypothetical electronics factory installed Kanbans on two lines first, then expanded to the entire workshop, only to discover insufficient switch ports and IP planning. The cost of rework would be very high.
4. Kanban content design must follow the "three-second readability" rule
Use colors and workstation numbers for alarms instead of dense tables. An ESD-type Kanban should focus on three key elements: current compliance rate, a list of abnormal workstations, and the timestamp of the most recent alarm. Solutions without a system often project entire inspection record tables onto the screen, which results in no one looking at them.
5. Establish inspection and alarm response mechanisms after launch
The Kanban is not merely decorative; it must coordinate who views it, how often it is viewed, and the response time for alarms. Systems with software support can set up automatic escalation notifications, while solutions without systems rely entirely on human monitoring.
Running a pilot in a small scope before replicating it is more reliable than deploying everything at once.
