Over the course of their careers, Sir Martin Sorrell, CEO of WPP; Randy Komisar, a partner at Kleiner Perkins Caufield & Byers; and Anne Mulcahy, Xerox’s chairman and former CEO, have made strategic decisions of all shapes and sizes.

While there’s no silver bullet, taking concrete steps to cultivate internal critics, safeguard diversity of thought, clarify assumptions underlying different points of view, and force tough choices between business priorities can help.
