The queue must separate pending diagnosis, parts waiting and authorized testing with owners responsible for removing each obstruction.
Index
Two stopped machines can require different actions; sorting everything by arrival hides items ready to move to testing.
The rule that changes the scope
The queue must separate pending diagnosis, parts waiting and authorized testing with owners responsible for removing each obstruction.
A task board organizes stages; customization connects physical equipment, dependencies and feedback to customer service.
The workshop may have limited physical space, so its queue should show equipment ready to leave rather than only completed service. Awaiting customer collection is another obstruction, different from a missing part. Demonstrate an order moving through diagnosis, approval, waiting and testing before returning to investigation. The equipment retains its identity, and every transition must show its supporting decision rather than inventing a perfectly linear progress sequence.
Specify operational deliverables
- Associate each machine with its order and the workshop's current recorded obstruction.
- Show who must act and the evidence releasing the next stage.
- Keep diagnosis changes without erasing the earlier waiting sequence.
Test the exception before acceptance
In a hypothetical scenario, a part arrives but testing needs another resource; the queue must update the obstruction without prematurely announcing completion.
