Many companies are starved for effective leadership, and as a result the demand for great interim executives who will come in and do the work is increasing. Consider this passage from the book Traction:
The inability to make a business vision a reality is epidemic. Consider it a new take on an old quote: Vision without traction is merely hallucination. All over the world, business consultants frequently conduct multiple-day strategic planning sessions and charge tens of thousands of dollars for teaching what is theoretically great material. The downside is that after making you feel warm and fuzzy about your direction, these same consultants rarely teach you how to bring your vision down to the ground and make it work in the real world.
