Timing: 20 mins
A customer wants to hire the subcontracting vendor who provides the quickest estimate to sorting a bag of coins. Have teams of participants bid on the project by shouting out bids (in seconds). Let all the teams attempt the exercise and hold them to their bids by timing them. After they have finished, point out that what the customer actually wanted, was to have the coins sorted by date, not denomination.
