Centrally planned systems work well in the beginning (like Apple's iPad, iPod)
but
In a large environment, a Self-Directed development works better.

Like your children, when they are born, you control everything.
Eventually they leave the nest and soar to new heights.
The success is based on all three, the nurture you give during the Centrally Planned phase, nature or environment your child flies into and finally, the Self-Direction of the new adult.

whoa. deep, I'm going to write that down.
