Today in business class we did an exercise called "Lost At Sea" which was basically a hypothetical situation. Your yacht (holy crap I have a yacht?) is going down due to a fire. Your best bet is you're a thousand miles out in the Pacific, you have five crew members, their pocket plunder, and these fifteen items. Rank them in importance.
Then get in the assigned groups and rank them as a group. No voting, or averaging allowed, you must persuade your group members.
Now here's what the Merchant Marines say the ranking should be.
Figure the difference between the Merchant Marines' ranking, your individual ranking, and your group ranking. Total the differences in each column.
The closer the numbers are for your individual ranking and the group ranking, the more influence you had, and the more managerial skills you have.
My numbers were identical.
And I still maintain that fifteen feet of rope is of higher importance to survival than a transistor radio! Or a quart of rum.
