Inventory Allocation Tabletop Exercise: A 60-Minute Workshop
Run an inventory allocation tabletop by giving a team less stock than customers need, requiring a shipment decision, then changing one constraint. This 60-minute workshop produces an allocation rule, an exception owner, and a customer communication plan.
How do you run an inventory allocation tabletop?
Give operations, sales, procurement, and finance one shared shortage scenario. Ask them to allocate available units, explain who must wait, and revise the decision when new information arrives.
For Q4 planning in September 2026, use a dated snapshot of stock, open orders, and supplier commitments. Keep confirmed replenishment separate from estimated arrivals so the team cannot solve the shortage with inventory that may never arrive.
Prepare the fictional shortage and assign roles
Use these invented exercise assumptions: 100 identical units are available against 140 units ordered for Friday. Customer A needs 60 units to avoid a production stoppage, B needs 50 for routine replenishment, and C needs 30 for a launch.
All orders have the same promised date and unit margin; partial shipments are accepted. B ordered first, then C, then A, and no replenishment is confirmed before Friday.
For a company-specific version, map the affected product and its upstream dependencies first. NIST's January 2024 article explains how mapping suppliers, their suppliers, and transport routes can reveal bottlenecks.

- Operations confirms available stock and records allocated units.
- Sales explains customer consequences and drafts revised commitments.
- Procurement distinguishes confirmed supply from estimates.
- Finance challenges the assumptions behind claimed business losses.
- An executive sponsor approves exceptions; a facilitator releases updates and records decisions.
Compare three allocation rules
Each option below allocates exactly 100 units under the opening assumptions. Choose a rule and explain its tradeoff; teams may propose a hybrid if they state how exceptions work.
| Allocation rule | Units to A / B / C | Tradeoff |
|---|---|---|
| Oldest order first | 20 / 50 / 30 | Honors order sequence, but leaves A exposed to a production stoppage. |
| Proportional allocation, rounded to whole units | 43 / 36 / 21 | Shares the shortage across customers, but may leave every customer below a useful quantity. |
| Protect A, then use order sequence | 60 / 40 / 0 | Covers A's stated need, but leaves C's launch without stock. |
Facilitate the 60-minute workshop
Treat the timings as a suggested agenda. Require a written allocation before each update so participants can explain why their decision changed.
- Minutes 0–10: read the brief, assign roles, and confirm who can approve the allocation.
- Minutes 10–25: allocate all 100 units and write a short message to each customer.
- Minutes 25–35: reveal that A can avoid a stoppage with 40 units this week. Reallocate stock or defend the original decision.
- Minutes 35–45: reveal that 20 units are now on quality hold and unavailable for shipment. Revise the allocation to total no more than 80 units.
- Minutes 45–60: compare decisions, identify missing information, and assign follow-up actions.
Debrief the decision and write an allocation rule
Check whether allocations stayed within available stock, customer claims were challenged, and someone owned each revised promise. Discuss which fact changed the decision most and whether the team would have requested it without a facilitator prompt.
Capture a reusable rule: prioritize verified minimum operating needs, apply an agreed method to remaining orders, and require a named approver for exceptions. Adapt that example to actual customer commitments before using it operationally.
Record the chosen rule, evidence required, exception owner, communication owner, and next review trigger. Assign each information gap a deliverable and due date, such as confirming minimum shipment quantities with key customers.
Frequently asked questions
Does an inventory allocation tabletop need simulation software?
No. This exercise needs a shared brief, a timer, and a spreadsheet or whiteboard that tracks available units and allocations. Keep a separate decision log so the reasoning survives each revision.
Is there one correct allocation in this supply chain exercise?
No single allocation is prescribed. Assess whether the team respects stock limits, checks customer needs, applies a defensible rule, and updates commitments when facts change. The tabletop rehearses judgment; it does not validate real inventory or supplier availability.
