How much is an action item worth to the team? Source:
Hang up the list of possible actions. Draw a column next to it, titled 'Importance (in $)'. The team gets to spend 100 (virtual) dollars on the action items. The more important it is to them, the more they should spend. Make it more fun by bringing paper money from a board game such as Monopoly.
Let them agree on prices. Consider the 2 or 3 highest amount action items as chosen.
