What Changes as You Grow
Arrangements that work with one supervisor and one site fail at twenty, and the transitions are predictable.
Prevention · Analysis
Most trouble here is an arrangement that was right at a previous size and was never revisited.
What breaks, and roughly when
Informal tolerance. Works when one person applies it; produces inconsistency the moment there are three supervisors.
Supervision as the identity control. Works where everyone knows everyone; fails with turnover and multiple entrances.
A single terminal. Fine for twenty people, a queue for eighty.
One person handling corrections. A bottleneck past a few hundred, and bottlenecked corrections become unpaid time.
Verbal policy. Works until the first dispute, at any size.
One rounding configuration for everyone, which becomes wrong as soon as pay groups differ.
The pattern
Each fails through accumulation rather than an event.
Nobody notices the shift when the tolerance started being applied differently by two managers.
It is noticed a year later as a grievance about inconsistency.
Which is the argument for the per-site measures: the value is catching a divergence while it is small.
The triggers to watch
Anomaly rates diverging between sites.
Corrections slowing.
Grievances mentioning consistency, which is the clearest signal of all.
Supervisors asking what the rule is, which means it is not written down clearly enough.
What to put in early
Cheap when small, expensive to retrofit.
A written tolerance, from the start.
Correction authority distributed to supervisors rather than centralised.
Failure logging, which is a procurement question and cannot be added later.
A rounding neutrality check in the calendar.
And the four system checks written down so any supervisor runs them in the same order.
The size-related mistake
Buying a control sized for a problem you have at one site and deploying it everywhere.
Anomaly rates differ by site more than by anything else, and a control justified at one location may be disproportionate at another — which is both a compliance point and a practical one.
Write the tolerance down early
Cheap at any size, expensive to retrofit.
An informal tolerance works while one person applies it.
With three supervisors it produces inconsistency, which is the single most common ground of successful challenge.
A written line costs nothing and removes the category.
And it can be generous — generosity that is stated is enforceable, while generosity that is informal is not.
