To survive a crisis, you have to double down on who you already are as a company. This is something Ellen Kullman knows, having led DuPont through the 2008-2009 financial crisis, and taken the CEO role at 3D-printing unicorn Carbon only weeks before Covid hit. Through her years as a leader, Ellen has developed four crisis principles that allowed her to lead teams and thrive through pandemic, economic meltdown, and beyond. The key? Practicing the principles in calmer times, before crisis hits. Because as Reid says: there's no such thing as a crisis playbook. There's just your playbook.
