In reply to Paul Simbeck-Hampson.

However the knowledge hoarding model begins to fail when it becomes cheap and easy to share and when the knowledge required to complete a task exceeds an individual's capability to learn in the time available.

This has been reflected in a longitudinal study of knowledge workers that Robert Kelley of Carnegie-Mellon University conducted over more than twenty years. He asked professionals "What percentage of the knowledge you need to do your job is stored in your own mind?"

In 1986 the answer was typically about 75%. By 1997 workers estimated that they had only about 15% to 20% of the knowledge needed in their own mind. Kelley estimated that by 2006 the answer was only 8% to 10%.

Given that professionals now need to draw 90% or more of the knowledge they need to do their jobs from others, in my view 'Knowledge equals Power' is no longer true.

I believe it is now more accurate to state Knowledge Shared equals Power Squared.
