“The consultation that takes place behind the closed doors of the CEO’s office or the board room is highly sensitive and absolutely confidential… It can be incredibly challenging and risky. But at the end of the day, it’s like any other kind of consulting: If you’re not producing results, you’re not invited back.”

From “Consulting to CEOs and Boards” by Mark B. Nadler and David A. Nadler in Management Consulting Today and Tomorrow
