I found a very interesting document over at ChangeThis, Lessons from a Starfish World written by Ori Brafman and Rod Beckstrom.

Such seemingly dissimilar groups as the Apache Indians, music swapping programs, Wikipedia, Alcoholics Anonymous and Al Queda have one thing in common: they are all starfish. According to Brafman and Beckstrom, each of these resilient groups succeeds because they are absent any hierarchy (head) and conventional organizations (spiders) best watch their backs.

I like this phrase in their text: Size matters. There is power in being small.

Lesson to learn: small and agile organizations can beat the big guys.
