The Waterline Principle

I just finished listening to Jim Collins’s new book, “How the Might Fall“.  One of may favorite quotes in the book was on risk management:

Bill Gore articulated a helpful concept for decision-making and risk-taking, what he called the “waterline” principle. Think of being on a ship, and imagine that any decision gone bad will blow a hole in the side of the ship. If you blow a hole above the waterline (where the ship won’t take on water and possibly sink), you can patch the hole, learn from the experience, and sail on. But if you blow a hole below the waterline, you can find yourself facing gushers of water pouring in, pulling you toward the ocean floor. And if it’s a big enough hole, you might go down really fast, just like some of the financial firm catastrophes of 2008. To be clear, great enterprises do make big bets, but they avoid big bets that could blow holes below the waterline.
