Shipping promise drift brief

Operational signals that show whether Shopify shipping promises are drifting because cutoff-recoverable orders are being mixed with next-wave overflow.

Claim

Shipping-promise control is stronger when teams record which orders can still clear the active cutoff, when the promise reset happened, and whether overflow was removed before more capacity was spent.

Recoverable same-day lane share: Orders still salvageable before cutoff

Shows whether the protected lane is still real or already overwhelmed by orders that need the next wave.

Promise reset lag: Time between lane failure and customer-facing reset

A long lag means the storefront keeps selling a promise after operations already know the queue cannot keep it.

Overflow carryover volume: Orders left in the same-day lane after reset

This reveals whether unrecoverable work is still consuming same-day capacity even after the rule changed.

Operational implication

Teams should log recoverable-lane share, promise reset timing, and overflow carryover together so cutoff pressure is corrected before promise misses spread into support and repeat-order trust issues.
