Number 03/Failure & fragility/Management
The Resolution Ratio
The quantity
The ratio of the process's characteristic scale to the observer's measurement resolution. Error introduced by management is predicted to scale inversely with it.
01Why it matters
It separates two failures usually conflated: bad decisions and under-resolution observation.
02Expected value
Management error should rise steeply below a ratio of about three, then flatten.
03How it would be measured
Compare the same process monitored at two resolutions with management decisions taken at each.
04What would refute it
If decision quality is invariant to resolution, the number is empty.
