WORK ORDERS
Kanban-driven work order lifecycle with preemption engine, mandatory inspection gates, parts auto-decrement, and zero-paperwork digital completion.
Kanban Board
The Kanban board is shared across all authorized roles in real time. A Dispatcher moving a card on their desktop is visible to the Technician on their phone within milliseconds. The board enforces a strict left-to-right progression — cards cannot skip stages or move backwards unless explicitly authorized by an Administrator.
Work order exists in the system. Not yet assigned. Visible to Dispatcher and Administrator.
Technician or Driver assigned. Technician receives push notification. Parts allocation begins.
Technician has acknowledged and is travelling to site. GPS tracking active, ETA calculated.
Technician has GPS-confirmed arrival. Clock starts. Work order becomes their active task.
Work underway. Parts can be logged. Notes added. Progress photos captured.
Mandatory inspection gate. Technician completes the required digital inspection form before advancement.
Technician has completed. Waiting for supervisor or client signature before closure.
All gates passed. Signed off. Audit record sealed. Machine status updated. Inventory decremented.
Cancelled with mandatory reason. Parts de-allocated. Full cancellation reason in audit trail.
Preemption Engine (Jour 12)
Inspired by operating system process scheduling, the Preemption Engine intercepts the normal work order queue when a critical task arrives. A P1 work order (machine down, safety event, or Dispatcher override) is injected at the top of the target technician's queue, pausing their current assignment with a full context snapshot.
The interrupted work order is not lost — it is suspended with all logged parts, notes, and elapsed time preserved. When the critical task is resolved, the technician is returned to their paused work order exactly where they left off.
Mandatory Inspection Gates
Each work order type can have one or more mandatory inspection gates. A gate is a specific digital inspection form that must be completed — with all required fields, photo evidence, and electronic signature — before the work order can advance to the next stage. It is technically impossible to close a work order without passing all configured gates.
Machine and site safety assessment before work begins
Photo evidence of each replaced part — before and after
Supervisor sign-off that work meets specification
Client signature confirming satisfactory completion
Parts Logging & Auto-Decrement
As the technician logs parts used during a work order, inventory is decremented in real time across all warehouses. The Parts Manager sees the stock reduction immediately. If a part falls below its reorder threshold after the decrement, a purchase order recommendation is generated automatically.
- ▸Part logged → inventory decremented atomically in the same transaction
- ▸Part search by name, part number, or 3D model location
- ▸Substitution tracking — if a different part was used than initially planned, both are recorded
- ▸Parts consumed per work order appear in the machine's permanent service history
- ▸Technician cannot log a part that is not in inventory (prevents phantom consumption)
