Great teams make great decisions for great reasons. Why we decide is just as important as what we decide. A team can make a decision that gets the best result but is also popular. The team leader is a real hero in this moment. A heroic moment like this is very dangerous because popularity is tasted and correlated with what’s best. Making an unpopular best decision for the team in the future will be much more difficult if the sentiment of popularity becomes part of the equation of decision-making.
