Make a realistic peak-shift plan with held orders and a fixed cutoff

Instruction: Calculate the theoretical maximum completed orders under the stated estimates, then recommend a realistic plan with its margin and tradeoffs. Explain lead-set priorities and a handoff preserving every order status.

Context:

Optional work sample for experienced associates: Written working is welcome. This is not a universal warehouse interview requirement.

It is 15:00 and the dispatch cutoff is 15:30; completing dispatch and the required handoff at exactly 15:30 counts as on time. You have one packing station, one scanner, and no confirmed help. The table describes 18 separate orders. Use the supplied times as planning estimates, with no overlap between tasks. All times already include each task's required checks.

OrdersCurrent stateRemaining time per order
R1–R12 (12 orders)Released to pack; all normal packing and dispatch work remains2 minutes
V1–V4 (4 orders)Packed and verified; final dispatch scan remains1 minute
H1–H2 (2 orders)Quality hold; no release decisionUnknown

The site also requires four uninterrupted minutes for the final reconciliation and handoff by cutoff. You cannot waive scans, release holds, or promise a late carrier departure. The lead decides order priority. Give a proposal the lead can approve.

Updated

Example answer

The estimates allow a maximum of fifteen orders, but that leaves no buffer. I would recommend fourteen: the four V orders and ten R orders, with four minutes for handoff and two minutes of margin. I would ask the lead which R orders take priority and flag that all sixteen eligible orders cannot fit. H1 and H2 remain held. My handoff would name every completed and pending order, and I would update the plan if actual progress differs rather than promise the maximum.

Worked plan

Order time available: 30 − 4 = 26 minutes. All eligible work: (12 × 2) + (4 × 1) = 28 minutes, so the deficit is 2 minutes before any disruption.

Theoretical maximum: 4 verified orders + 11 released-to-pack orders = 15 orders, using all 26 work minutes plus the four-minute handoff. Remaining: 1 eligible order + 2 held orders. This has no buffer and is conditional on the estimates holding.

A realistic recommendation is 14 orders: all four V orders plus ten R orders use 4 + (10 × 2) = 24 work minutes. With four minutes for handoff, that leaves 2 minutes of margin. If the lead selects R1–R10, complete V1–V4 and R1–R10; retain R11, R12, H1, and H2 as pending, with the two H orders still held. Different priorities can change the selected identities or completion count. Reconcile actual progress rather than mark the proposal completed in advance.

Assessment criteria

  • Reserves the four-minute handoff, calculates the two-minute demand shortfall, and identifies the theoretical maximum of fifteen.
  • Gives a feasible recommendation, explains its margin and tradeoffs, and accounts for all remaining orders and holds.
  • Seeks priority direction and updates actual statuses without removing checks or assuming extra resources.

Stronger answer: distinguishes the maximum from a sensible commitment, then shows exactly which orders remain when the recommendation uses a buffer.

Acceptable alternatives: Fourteen orders with two minutes of margin is a sound recommendation. Fifteen can be presented as an explicitly conditional zero-buffer option; a lower completion count can also be justified by lead-set priorities or a stated margin. Score correct capacity, honest tradeoffs, and complete statuses rather than requiring the recommendation to equal the maximum.

Material mistakes: Calling fifteen guaranteed or the only acceptable plan, omitting handoff time, counting unconfirmed help, releasing H1/H2 without authorization, or losing the identities of unfinished orders when switching plans.

Follow-up question

What belongs in the handoff?

Actual dispatched identifiers and count; every remaining eligible order and its last completed step; H1/H2's hold reasons and owner; any new exception; and the agreed next action. For the illustrative fourteen-order plan, R11 and R12 remain eligible but unfinished, while H1 and H2 remain held. The actual approved selection determines the final identifiers.

Pressure test

Before work starts, a safe-area closure removes four minutes, and quality releases H1, which needs two minutes of work. H2 remains held.

The revised order capacity is 30 − 4 closure − 4 handoff = 22 minutes. Eligible demand is now 30 minutes: the original 28 plus H1's two, an eight-minute deficit. The theoretical maximum is four V orders plus nine two-minute orders, completing 13 with no buffer. Four eligible orders and H2 remain.

A buffered recommendation is four V orders plus eight two-minute orders: 12 orders use 20 work minutes, leaving 2 minutes of margin after the closure and handoff. For example, if approved priorities select H1 and R1–R7, complete those plus V1–V4; R8–R12 remain eligible and H2 remains held. Ask the lead to choose the eight, report the reduced capacity, preserve all required checks, and update the actual handoff. A different justified priority selection is also valid.
