Decision making in times of unusual uncertainty is one of the greatest, perhaps the single greatest, challenges of leadership. Navigating the current COVID-19 crisis and crafting appropriate responses has been a challenge for leaders around the world. And whatever happens, we are likely to have years of second-guessing as to what we could have done differently. To some extent this is inevitable – with so many unknowns, it is a certainty that we either over-reacted or under-reacted, deploying certain measures either too early or too late; and we may never know which, as we cannot go back in time and try something different.
