Operator Dashboard & Andon Template Pack

Purpose

This template pack helps teams provide operators with uncluttered, role‑specific real‑time displays and Andon flows. The goal: surface the few signals operators need to stop a line, start recovery, or call a huddle—while preserving troubleshooting context for continuous improvement.

What's included

• Daily KPIs view: OEE, throughput, quality rate and brief context cards for planned vs actual and shift targets.
• Active alerts panel: prioritized actionable alerts showing required action, current owner, time since trigger, and quick action buttons (Acknowledge, Start Recovery, Escalate).
• Short‑term trend view: rolling 15–60 minute trend lines for the few signals tied to recovery decisions (cycle time, reject rate, line speed, machine status).
• Example Andon workflows: standard stop/recover/escalate paths with recommended timers, owners, and fallback contacts.
• Implementation checklist: data sources, refresh cadence, acceptance tests, operator training steps, and verification script.

Design & layout rules (operator-first)

1. Limit the primary screen to the 3–6 items operators must act on. Place them in the top-left or center for fastest eye path.
2. Use consistent visual language: neutral background, single accent color for normal state, one warning color, and one critical color. Avoid more than three semantic colors for state.
3. Give each alert a single clear action: Acknowledge, Start Recovery, or Call Huddle. Actions should be one tap/click on touch panels.
4. Show minimal context: recent events, last corrective action, and owner history. Keep troubleshooting details one tap away—not on the main action surface.
5. Use large legible type for status and times. Reserve small text for identifiers and change logs.
6. Design for multi‑shift use: include a visible timestamp and shift selector so values make sense during handovers.

Alert types & actionable triggers

Design alerts as one of three action categories:

• Immediate stop (Critical): conditions that require stopping production (safety, major quality breach, uncontrolled equipment failure). Trigger: predefined sensor/state or calculated condition (e.g., quality defect rate > X% for Y parts). Action: stop line, call maintenance, log reason.
• Recovery required (Actionable): issues that allow recovery without full stop (tooling, minor jams, recoverable defect cluster). Trigger: sustained deviation for a short window (e.g., cycle time > 115% for 3 minutes). Action: start recovery procedure, record steps.
• Monitor / Informational: trends worth watching but not immediate action (slow drift in throughput). Show as unobtrusive trend card; auto-escalate to Actionable if the condition persists or worsens.

Example Andon workflow (textual)

1. Operator sees Critical Alert: stop line immediately.
2. Operator presses Stop & Alert. Dashboard shows required action checklist and auto-notifies Primary Owner (maintenance) and Supervisor.
3. If Primary Owner does not acknowledge within configured timeout (e.g., 2 minutes), auto‑escalate to Secondary Owner and Supervisor with SMS/visual alert.
4. Primary Owner acknowledges, records immediate corrective steps, and starts recovery. Operator updates dashboard with recovery status.
5. After recovery, team completes root cause notes on the incident card and schedules a short huddle if the event meets criteria for follow‑up.

Prevent alarm fatigue

• Verify each alert with real data before announcing it on the operator surface. Use short debounce windows and majority‑vote logic when sensors are noisy.
• Rate‑limit informational alerts to avoid repeated visual churn. Aggregate repeated low‑severity events into a single actionable summary.
• Provide an operator override to silence noncritical alerts for a short period during controlled recovery—record the reason and duration.

Data & integration guidance

Preferred data cadence for operator surfaces is 5–60 seconds depending on signal volatility. For true production control (stops, safety) use event-driven messages from PLC/MES. For derived KPIs (OEE), synchronize base measurements (availability, performance, quality) and document calculation windows and assumptions.

Record the source, last update time, and calculation method on each KPI card so operators and auditors can trust the numbers.

Standard work & operator interactions

Each dashboard action should map to standard work: what the operator does now, what they document, and who they notify. Provide a one‑click link to the short recovery checklist and a required confirmation (yes/no) when leaving the acknowledgment action.

Sample KPI definitions

• OEE: Availability × Performance × Quality. Document stop categories included in Availability and the time base (shift/rolling 24h).
• Throughput: good units per minute (or per shift) with target bands shown.
• Quality rate: (good units / total units) × 100%. Show both percent and absolute scrap counts.
• MTTR / MTBF: mean time to repair and between failures for critical equipment—used by maintenance dashboards and escalations.

Deployment & acceptance checklist

1. Identify the operator Hungers: what decisions must they make from this screen?
2. Map data sources and confirm signal quality with a 1‑week test feed.
3. Configure alert thresholds and debounce logic; run an alert simulation with operators on shift.
4. Train operators on new actions and standard work; run a pilot for at least one shift per cell.
5. Collect operator feedback and iterate—keep the screen lean and stable.
6. Define acceptance tests: response times, acknowledgement rates, and false positive rates below an acceptable threshold.

How to adapt this pack

Use these templates as a starting point. Copy them into a local domain, tailor KPI calculations, update escalation contacts, and version control your templates. Keep the primary operator surface consistent across shifts and allow secondary views for supervisors or maintenance with deeper context.

Next-step capability opportunities

This static dashboard pack maps naturally to interactive improvements: capture operator confirmations and recovery notes through on-screen forms, store event history for analysis, and expose occupant metrics to downstream analytics and agents that can suggest corrective actions.
