To successfully navigate the uncertainty that characterizes today's rapidly changing and unpredictable world, leaders must ensure that their teams are proactively prepared for unexpected emergencies. Space exploration and healthcare dominate the market at this level of readiness. From takeoff and landing of a space shuttle to managing uncontrollable bleeding in an operating room, there are important lessons to be learned from these industries and adapted to other industries. Start by proactively envisioning your worst-case scenario through brainstorming sessions, scenario planning, and risk assessments. Then prepare for those emergencies through training and practice. Finally, create a psychologically safe environment so everyone on your team can communicate safely.
