Twelve-to-twenty-minute games & tools spanning negotiation, procurement strategy, decision-making, spend analytics, operations, inventory, and sustainability. Drop them into a lecture, a workshop, or a coffee break.
Open strong — the first number you say does most of the work.
Five micro-scenarios. Pick your opening offer and see how anchoring shapes the deal you eventually get.
Twelve cognitive traps under pressure.
Rapid-fire scenarios. Identify the bias in play before the timer hits zero. Streaks earn bonus points.
Don't split every issue 50/50 — trade away the ones you don't value.
A four-issue negotiation where you and the counterparty value the issues differently. Build a package across several rounds; the counterparty concedes on what it doesn't care about and holds what it does. Find the trades that grow the pie instead of dividing it.
Find the savings hidden in the data.
Five rounds: where to consolidate, where to tender, where the maverick spend is, where you're over-exposed to a single supplier, and how much you'd realistically save.
Pick a method, tune the dials, survive the regime shift.
Four canonical methods — Naive, Moving Average, Simple Exponential Smoothing, Holt's trend — all on one live time series. Switch methods and retune α / δ / n any week. A regime shift mid-game separates adaptive from anchored. Debrief replays your stream through every method so you see what would have won.
Your supplier missed the deadline. Your line stops in 96 hours.
Five decisions across one week of fallout. The first move branches; the next four follow a single timeline. Once you escalate, you can't un-escalate cheaply.
The tariff is announced, not applied. Move now, move later, or hold?
Eight quarters, four sourcing regions, a news ticker that mixes real trade shocks with rumours that never land. Re-allocate volume as the world lurches — every move costs requalification.
Five workstations. Average capacity 3.5. Why doesn't the chain deliver 3.5?
Goldratt's dice game in your browser. Predict throughput, then watch statistical fluctuation and dependent events conspire against you. Three rounds, three insights.
Diagnose the chart. Then prescribe the fix.
Two phases of quality management. First spot the out-of-control signals on a live control chart (Western Electric rules). Then tune the process — recentre the mean, reduce variability, hit Cpk ≥ 1.33 within budget. The lesson: in control ≠ capable.
Sales wants stock. Finance wants none. HR wants no churn. Pick two.
Twelve months of seasonal demand, three dials a month: workforce, overtime, build-ahead. Chase the forecast or level the plan — then a viral spike tests whichever you chose.
Order too few, lose sales. Order too many, throw out cash.
Twenty nights running a sandwich cart. Set tomorrow's order before you know demand. The critical ratio is hiding in plain sight — find it before round 20.
Four warehouses or one? Same demand. Watch what happens to safety stock.
Side-by-side: a decentralised network and a centralised one, same total demand and variance. Slide the service level. The √n law shows up uninvited.
Crank service to 99.9% — and watch the inventory bill go vertical.
Set the reorder point on a live demand-during-lead-time curve, then run cycles where stochastic demand either gets served or stocks out. Re-tune between cycles to balance holding cost against lost sales — and discover why the last few points of service cost the most.
Find the order quantity. Then a supplier dangles a discount.
Slide the order quantity over the classic three-curve cost chart to find the economic order quantity. Then a price-break table appears — decide whether the quantity discount is worth inflating your order past Q*.
Six everyday products. Rank them by carbon. Then do the math.
First rank by gut. Then surface use-phase vs embodied emissions per product. The hybrid car still wins — and not in a good way.
Forty suppliers. Budget to audit five. Choose before the year happens.
CSDDD just landed on your desk. Desk-screen the supply base, pick five audits and ten monitoring slots, then watch the year play out — including the supplier you waved through.
Made for teachers and students. Anonymous play, no account needed.
