The illiterates of 21st Century.

The illiterates of 21'st century will not be those who cannot read and write but those who cannot learn, unlearn and learn again - Future shock.

One school of thought feels writing on a clean slate is more easy today and hence would prefer to hire outside the industry rather then look inside when ever a radical change is required. Some such experiments have yielded good results. The tribe is increasing. Managers from unrelated industries who quickly understand the basics and try to keep it simple have been successful.

Those who refuse to unlearn tend to loose out in the long run. They move into obsolescence and then develop a phobia to change. We know the case of the frog refusing to jump out even when the temperature of the water goes up.

Change is constant and change does not mean changing jobs only, it can be a change in the way one works, behaves or manages stakeholders.
