The kind of teams I am suggesting are more like banana splits than milkshakes. Milkshakes blend the various flavors of ice cream, toppings, milk, and other ingredients into one undifferentiated dessert. In banana splits, each scoop of vanilla, chocolate, and strawberry ice cream, along with the bananas and toppings, remain separate until eaten. In a banana-split team, individuals play special roles and maintain their identities. The sum of the parts is greater than the whole.
