Software may not show the queue. A board shows ready, waiting, quarantined and loaded work.

Separate physical states. Use the board as a shift decision surface, not a replacement for the main system. A stale card shows a false state.

Card fields

  • Container and trip ID
  • Current state
  • Next task
  • Responsible role

Record movement

Set columns by workflow. Link container movement and card updates to the same standard task.

At shift end, reconcile ownerless cards with system records.
