Andon

Andon · Exception Calling & Response Tracking

Break the shop-floor habit of operators struggling alone while problems stay buried. Call for material, quality, maintenance or a supervisor with one tap, with multi-channel push across a three-color tower light, wall display, WeCom and DingTalk. Response times are measurable and accountable — and only when problems surface can they be improved.

Capabilities

Core Capabilities of the Andon System

A complete loop from call to response to statistics

📞 One-Tap Calling

Multiple triggers — physical buttons at the workstation, PDA, or touch on the wall display — covering 4 categories: material, quality, maintenance and supervisor

🚦 Three-Color Tower Light

Tower light + buzzer above the workstation / line, with red, yellow and green for different severity levels, visible from afar

📺 Shop-Floor Wall Display

The wall display shows the live list of unanswered calls with timers, making it obvious who hasn't responded

📲 Mobile Push

Push to the responsible person via WeCom / DingTalk / WeChat mini-program — receive calls even away from the workstation

⏱ Response-Time Tracking

Three phases — call, arrival, completion — are measured separately, with TTR / MTTR calculated automatically

📈 Pareto Improvement

Top 3 call causes are automatically charted as a Pareto diagram, driving continuous shop-floor improvement

One-Tap Calling: No More Bottled-Up Exceptions

In the past, when operators hit a material shortage, breakdown or quality issue, they either pushed through it (causing quality problems) or left the workstation to find help (widening the line stoppage). Andon turns "calling someone" into a one-second action: press the button or tap the PDA, and the right person is notified automatically.

Material call: shortage / material anomaly, handled by the material handler
Quality call: suspected defect, handled by IPQC
Maintenance call: equipment anomaly / breakdown, handled by maintenance technicians
Supervisor call: on-site issues needing a decision, handled by the supervisor

Multi-Channel Push: Guaranteed 100% Reach

A flashing light isn't enough — the supervisor may be in the warehouse, the technician in the next workshop, and quality in the office. The three-color tower light + shop-floor wall display + mobile IM fire together to guarantee 100% reach.

Red call: urgent safety or line-stoppage issue
Yellow call: quality anomaly or material shortage
Green call: routine support or suggestion
No response in 30 seconds: auto-escalation to the next-level manager

Response-Time Tracking: Make Response Speed a KPI

Andon isn't for show. The system records each call's TTR (time to respond) and TTF (time to fix), aggregated by responsible person / team / month and tied into performance reviews. Fast responders get recognized, slow ones get attention — and behavior naturally changes.

TTR (time to respond): from call to on-site
TTF (time to fix): from on-site to closure
SLA settings: different time limits by category
Monthly leaderboard: top 3 fastest responders publicly recognized

Use Cases

Andon in Action Across Different Shop Floors

Auto-Parts Assembly Line Andon

50 tower-light buttons across assembly stations; one-tap calls for material shortage / breakdown / quality anomaly, with a mandatory 5-minute response

SMT Changeover Support

During SMT changeovers, a button call summons the process engineer for support, preventing new operators from erring on guesswork

Injection-Molding Quality Call

When product appearance is off, call quality inspection; production continues only after an OK confirmation, avoiding batch scrap

Food GMP Violation Call

Report hygiene / process violations the moment they're spotted; QA steps in within 30 minutes
