Stress-test an inbound dock backup by proving that each hold window and restore rule can place inbound freight inside the planned lane, survive override pressure, and avoid trapping receiving inside a green dock slide that hides long-lived backups.
Inbound dock backups often list a surge plan while leaving restore behavior, override authority, and abort ownership implicit. Those edges decide whether a late trailer stops inside the backup packet or leaves a broken receiving path live under peak load. The exercise should follow actual appointment timelines, door maps, and escalation paths rather than a clean surge deck.
Trace the hold path
List every dock class with its hold window, waive rule, override behavior, owners, and notification channels. Mark paths that cannot reverse without a manual amendment. Attach the last three inbound backup incidents with raw timelines and any waivers. Include the source of truth for open appointment counts during the observation window.
Define the phases for detect, hold, divert, abort, and restore. Each phase needs an owner and an exit condition. Write the point after which a stuck trailer would require a different procedure, then review whether that action is still permitted. Capture maximum acceptable dwell in measurable units, including which carriers are excluded from the backup and why.
Include the calendar of known events for the next two quarters: promotions, carrier cutovers, and warehouse freezes that shrink the usable hold window. A backup budget that ignores those dates will look calm until the week they land.
Pressure drills
- A minority high-volume carrier keeps a side-channel while the aggregate dock dashboard stays green.
- A restore has already left a receiving surface without a trusted appointment state.
- The primary dock dashboard lags beyond the planned observation window.
- An operator skips a hold gate because a promo inbound deadline is near.
- Automated and human divert messages collide under the new backup rule.
- Abort authority is unclear at week end and the update lands on the wrong amendment.
For each drill, identify detection time, freight impact, containment, and the authority to force a backup rollback. Require commands and dashboard links in the runbook. A claim that monitoring will catch it does not establish which alert fires or who receives it.
Prove timing and owners
Run the package in Pingpong with logistics, warehouse, inventory, and finance seats. Ask logistics which receiving decision becomes unsafe first if holds still stick after the claimed window. Ask warehouse whether door macros can absorb a forced override. Ask owners to show the exact appointment version or export used as the exit condition.

Authorize the published inbound dock backup only after a timed drill restores usable receiving hygiene inside the documented budget without an undocumented manual step.
