The final lesson states the boundary: deterministic capacity snapshot arithmetic only.
Deterministic Snapshot
The model uses deterministic capacity and output inputs.
deterministic snapshot \text{deterministic snapshot} deterministic snapshot Capacity snapshot The same chart shows the base snapshot and the higher-output what-if. what-if capacity snapshot utilization 2/3; efficiency 4/5; cushion 1/5 measure value meaning design capacity 120 maximum snapshot rate effective capacity 100 usable snapshot rate actual output 80 observed output design gap 20 design minus effective capacity cushion 1/5 unused effective share design design 120 effective effective 100 actual actual 80 what-if actual what-if actual 90 what-if utilization 3/4; efficiency 9/10; cushion 1/10
Not a Forecast
It does not forecast demand or explain downtime causes.

Not a Bottleneck Proof
It does not measure quality, decide staffing, or prove a bottleneck.

Honesty Note
This is deterministic capacity snapshot arithmetic only. It does not forecast demand, explain downtime causes, measure quality, decide staffing, or prove a bottleneck.
