Defect found—QC stops the line; rush order—supervisor restarts. When a senior arrives, andon rules vanish. Line-stop authorization must state: who can stop, who can restart, what evidence restart needs. Rank is not permission. Permission lives in role tables—stop/restart survives audit and customer complaints.
Rank solves organization. Authorization solves whether this minute can move. Don't mix the two.
Stop Cleanly, Restart With Evidence
Quality, equipment, and safety each have stop keys. Restart needs cause closed, first-piece or inspection pass. Unauthorized restart is an incident. Andon duration hits dashboards—no shouting it shorter.
- Ban "restart first, paperwork later."
- Visitors and leadership on site don't change authorization.
- Nights and overtime follow the same rules—no verbal override for system.

Roles Written on the Andon
The XYN digital intelligence system makes stop/restart role-bound events—not floor votes. Smart manufacturing discipline is authorization, not volume. Volume can rush goods; authorization keeps goods qualified.
Check last week's stops—how many restarted without role? If any, fix authorization table before talking downtime reduction.
