Explain why a farther location can receive the whole order

State the ranking contract before inspecting the result

Shopify’s order-routing guidance, checked 7 November 2026, applies rules sequentially to the preceding results. Its documented default prioritizes minimizing splits, then staying within the destination market, then proximity. Verify the actual store configuration; a default described in documentation is not evidence that the account still uses it. This lesson makes no driving-time or delivery-speed inference from geographic proximity.

Write the complete synthetic order, including each variant and quantity. Identify the candidate locations and the stock evidence appropriate to the operation. Keep existing reservations and unsupported fulfillment routes visible as exclusions supplied by the responsible owner. A product-family total cannot establish whether a location can assemble the particular order, and a shelf quantity is not automatically an available picking quantity.

Build an order-coverage sheet

Consider an invented request for two X units and one Y. North has two X and no Y; Central has two X and one Y; Border has two X and one Y. North and Central are inside the destination market, while Border is outside it. A supplied proximity ranking places North first, Border second and Central third. These are fixture labels and rankings, not real warehouse locations or travel estimates.

Write a complete-order coverage result for each row before applying the preferences. North cannot supply the entire request from its stated stock; Central and Border can. Under the stipulated split-first objective, the latter two are the preferred candidates for the next comparison. Keep the reason beside the result instead of merely coloring the chosen row green. That explanation is what lets another reviewer reproduce the decision.

Apply the remaining objectives without restarting the comparison

Among the complete-order candidates, the stipulated market preference favors Central over Border. Proximity therefore does not restore North to the preferred result just because it is nearest. The selected location is Central, the farthest in the supplied ranking. This is not a defect by itself: it follows the declared objective order for the fictional inputs. Show the surviving preference after each stage so the conclusion is inspectable.

Now change only the stock fixture: Central has no Y, while Border still covers the complete order. Ask the responsible owner to confirm whether Border is an eligible cross-market fulfillment route before proposing any assignment. An eligibility prohibition is not merely a low preference. If that route is forbidden, return the case as requiring a different feasible plan rather than letting the ranking worksheet grant permission to cross a commercial boundary.

Compare a supplied assignment with the derivation

For an observed disagreement, first reconcile the input snapshot and actual rule order. Identify whether the difference comes from coverage, market eligibility, configured priority or unresolved data. Do not change a location’s recorded stock or address to make the desired assignment appear. If the declared objectives themselves produce an unwanted commercial result, route that policy decision separately from an implementation defect.

Retain the order-coverage sheet and staged comparison with the configuration evidence. A later stock change requires recalculation, not blind reuse of the earlier result. Keep parcel notifications and customer delivery promises downstream, with their own verified events. This exercise creates no order, changes no routing rule and commits no warehouse inventory. It demonstrates why the proposed choice follows a bounded allocation contract, not that the choice is cheapest or fastest in every circumstance.

Make the reasoning concrete.

A fictional campaign coordinator expects the nearest store to receive every order. The supplied three-location fixture instead selects Central, which can fulfill the complete basket within the destination market.

The coordinator accepts the explanation for the original fixture and holds the changed-stock case until route eligibility is resolved. No actual assignment is modified.

Take the questions into your next brief.

Use these prompts in your own notes. Nothing is submitted from this page.

1. Order

   What exact variant quantities must be supplied together?

2. Candidates

   Which locations are genuinely eligible for this operation?

3. Coverage

   Which candidate can fulfill the complete synthetic request?

4. Priority

   What does each successive objective prefer among the preceding results?

5. Disagreement

   Which input or configured priority explains the observed difference?

Watch for the wrong conclusion.

• Changing an input to force a preferred result.
• Treating a prohibition as merely a lower ranking.
• Calling proximity proof of a faster delivery promise.
