Your spacecraft has crash-landed on the sunlit side of the moon, 200 km from the nearest lunar base. The mothership is undamaged but can only pick you up at the base. You must travel on foot.
Fifteen items survived the crash. Your task: rank them from 1 (most important) to 15 (least important) for your 200 km trek to the lunar base.
Phase 1: Each person ranks independently (7 min). Phase 2: Your team agrees on a consensus ranking (10 min). Then we compare to the NASA expert answer — and discover whether teams outperform individuals.
1 = most important for survival, 15 = least important. Each rank must be unique (1–15).
Update any item. Last write wins. When your team agrees, submit.
Deviation = |your rank - NASA rank|. Green = 0–2 off. Yellow = 3–5 off. Red = 6+ off.
You made it back to lunar base. Great teamwork out there.
