EVW — Expected Value of Waiting

EVW — Expected Value of Waiting — is the dollar value of delaying a commit by one day. Computed as the expected EVA difference between committing today versus waiting until tomorrow, where waiting gives the system one more day of incoming events and refined distributions before the commit is locked.

The autonomy threshold is conventionally based on value at risk — how much money is on the line. But some decisions with low value at risk have high information value. A decision that becomes substantially clearer with one more day of supplier confirmations, or one more day of customer pull-in patterns, may not be worth auto-committing on Day N — even if the dollar exposure is small — because Day N+1's information would change the answer. EVW captures that second axis.

High-EVW decisions surface to humans even when value at risk is low. Low-EVW decisions auto-commit even when value at risk is high (because waiting buys nothing — the supplier window closes, the customer slot is taken, the answer doesn't improve). Three MIC examples illustrate the shape:

A PO release with $2M value at risk but $20K EVW auto-commits. The waiting buys nothing — the supplier's commit window closes end-of-day, the lead-time distribution is well-known, the decision quality won't improve overnight. A $50K value-at-risk decision with $80K EVW surfaces to a human. The waiting clearly buys more than the decision is worth — tomorrow's confirmations from three pending customers will resolve the question. A $200K value-at-risk decision with −$5K EVW auto-commits. Waiting actively destroys value because the supplier's capacity window is closing, even though the dollar at risk is substantial.

EVW with resilience together form the auto-commit envelope. A high-resilience, low-EVW decision auto-commits with high confidence. A low-resilience, high-EVW decision surfaces with detail. The two axes capture different aspects of decision quality and the policy can configure thresholds for each independently.
