What-If and Scope

Honest Kanban Sizing Scope

The card count is exact arithmetic for this pinned snapshot, not a stochastic service guarantee.

Deterministic Snapshot

This example sizes cards from fixed demand, lead time, safety stock, and container size.

Honesty Note

This is deterministic kanban sizing arithmetic only. It does not model demand uncertainty, service levels, supplier reliability, scheduling, queueing, or empirical performance.
