We think of unusual events as rare - but as my Friday Fireside Chat guest, Jonathan Brill, points out, they may be rare individually, but when they accumulate, the chance of their creating a catastrophic inflection point increases. Indeed, his research finds that most firms in the US have faced four significant calamities every year! These are what he calls "rogue waves" or events in business that are like the huge waves that can come seemingly out of nowhere to sink even large ships. While he was at HP, he had the amazing title of Global Futurist and Director long term research. He talks about how you get people to pay attention to the possibilities, how to change behavior and how to change culture so that the action needed today to be resilient in an uncertain future is taken.
