Fable
The escort agency said it was carrying the goods, but the accountant discovered three more teams took over along the way
The key here is to apply the concept's constraints to specific objects, rather than merely describing an outcome.
As scale and exceptions increased, the methods previously held together by ad hoc coordination began to expose blind spots.
Short-term patches restore surface order, but do not address what the concept truly constrains.
The old craftsman turned to recording conditions, actions, results and the chain of responsibility, so that subsequent adjustments had evidence to rely on.
Later every external shop registered: what was taken, which step could be done, how long it was kept, to whom it must not be transferred, and how errors would be reported. This step was troublesome and at first slowed the schedule; but after several rounds, rework decreased, and the masters no longer changed rules on a whim. Everyone finally saw that delegating to a third party does not transfer responsibility; the supplier's scope, protection obligations and exit arrangements must all be traceable.
Delegating the work does not transfer responsibility; external hands must also enter the boundary and undergo inspection.
During a pre-wedding spot check, a small shop's damp warehouse was discovered in time, and the curtains were not scrapped. From then on, delegating the work did not make the responsibility disappear; outside hands also had to enter the same set of boundaries and inspections.
