Rumors are circulating that RIM will soon shake up its leadership by appointing a new chairman. The maker of the BlackBerry smartphones has had a rough year, and is quickly losing relevance. A change at the top may bring some fresh perspective and new vision, but expecting a new chairman to be a white knight that saves the company may be asking too much.

The role of chairman at RIM is currently filled by two people. The co-CEOs, Jim Balsillie and Mike Lazaridis, are also its co-chairmen. While the saying suggests that “two heads are better than one,” the chaos at RIM seems to indicate instead that “too many chefs spoil the soup.”
