Warehouse Outages: "A Fallback Plan You Can't Measure Doesn't Exist"
A warehouse can have freight ready at the dock when a systems outage cuts off the order feed and the carrier’s booking information. The shipper may know which deliveries cannot wait, while the warehouse has the stock and the carrier has the vehicle. Until those parties can share an agreed order record and authorize a handoff, the load can still miss its departure. An outage drill gives the three teams a chance to see where that handoff breaks under controlled conditions. The useful result is a measured account of which shipments moved, how long they took to release and what errors the fallback introduced.
Makoto Yabe, representative director and CEO of Logience Consulting Co., Ltd., suggested starting with the previous day’s shipment data and having the shipper, warehouse and transport provider walk through a simulated outage. The exercise should establish which loads take priority, who can release them and how each party learns that a decision has been made. In a written response to The Supply Chainer, Yabe summed up the test: “A fallback plan you can't measure doesn't exist.” A team can use the exercise to identify which order fields and approvals must still be available when the normal system is down.
Measure the First Dispatch and the Errors That Follow
Yabe recommended moving a limited set of customers to manual processing during a controlled test. He proposed measuring the time to first dispatch, the share of normal throughput the partners can sustain and the rate of incorrect shipments. A quick first departure may mask a growing queue or errors that appear only when the warehouse and carrier reconcile their records. The three measures give the partners a way to judge speed alongside accuracy and capacity. Yabe described a test method and supplied no measured results from an actual drill.
Put Joint Testing into the Service Agreement
Gary Cannon, global transport lead at NCC Group, raised a related question in a statement quoted in earlier The Supply Chainer coverage of the CEVA Logistics cyberattack. He urged organizations to examine “whether contingency plans are in place if a critical partner suddenly becomes unavailable.” Yabe proposed requiring annual tests in service-level agreements and keeping essential order data accessible to the shipper. For a warehouse and carrier, an agreement can also specify who escalates a missed target, what records each party retains and how the team will reconcile the manually processed loads when its systems return.
The first drill gives the partners a baseline against which to set a recovery target. If the first dispatch is late because nobody can verify the order, adding vehicles or dock labor may do little to help. If dispatch is quick but the wrong goods are handed over, the teams need a stronger check before release. The next exercise can test whether that specific change improves the handoff at the same level of demand.
