Managing risk effectively has always been a touchstone of the most successful companies. But in today's risk-filled business environment, it can be hard for executives to have confidence that their plans and strategies will play out as expected. A big reason is that strategic risks -- those that either affect or are created by business strategy decisions -- can strike more quickly than ever before, hastened along by rapid-fire business trends and technological innovations such as social media, mobile and big data. Companies that fall behind on the innovation curve may quickly fall prey to innovation's evil twin -- disruption. That is just one of the reasons managing strategic risk has become a high priority for many executives.
