It’s a new year with big business challenges. You would have thought CEOs would be worried most about the impact of Covid – but not so. That’s #13 on their list. Disruption is the #1 fear. The frenetic pace of change in businesses and the world has accelerated during the pandemic. An Alix Partners study released on December 27 revealed almost every CEO (94%) surveyed said their company needs to reinvent the business model within the next three years. 57% fear they’re not moving fast enough. The situation is also spiking CEO anxiety: 72% of CEOs fear losing their jobs due to disruptions facing their industries. That is an unprecedented level of anxiety. All this comes as no surprise to veteran Fortune senior editor-at-large GEOFF COLVIN. He's been speaking and reporting on business model transformation for years – watching how leaders are leading the change that keeps their companies competitive and relevant. Here's a great example of Geoff's reporting and research – a Fortune profile on how Goodyear has reinvented their business. Geoff also co-hosts a Fortune podcast and a recent topic was GM's transformation towards electric vehicles.
