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.
A complete loop from call to response to statistics
Multiple triggers — physical buttons at the workstation, PDA, or touch on the wall display — covering 4 categories: material, quality, maintenance and supervisor
Tower light + buzzer above the workstation / line, with red, yellow and green for different severity levels, visible from afar
The wall display shows the live list of unanswered calls with timers, making it obvious who hasn't responded
Push to the responsible person via WeCom / DingTalk / WeChat mini-program — receive calls even away from the workstation
Three phases — call, arrival, completion — are measured separately, with TTR / MTTR calculated automatically
Top 3 call causes are automatically charted as a Pareto diagram, driving continuous shop-floor improvement
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.
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.
Avg TTR by team (min)
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.
50 tower-light buttons across assembly stations; one-tap calls for material shortage / breakdown / quality anomaly, with a mandatory 5-minute response
During SMT changeovers, a button call summons the process engineer for support, preventing new operators from erring on guesswork
When product appearance is off, call quality inspection; production continues only after an OK confirmation, avoiding batch scrap
Report hygiene / process violations the moment they're spotted; QA steps in within 30 minutes
Andon is the shop floor's nervous system, connecting every person and every event
An inspection NG automatically triggers an Andon call
Equipment-breakdown maintenance calls route through the Andon channel
Calls pushed to WeCom / DingTalk / WeChat
