ne of the most common mistakes of leaders of all experience levels is failing to act in a timely manner on poor performers. This is certainly consistent with our firm's findings in interviews and surveys over the past two years, where the winner for number one self-described weakness was delivering constructive feedback. (Choose your label: constructive feedback=the tough performance discussion, robust dialog or candid conversation.) Apparently, many of us are wired with a naive sense of optimism and a willingness to continue throwing good time and money after bad in the never-ending hope that the poor performer will see the light, make adjustments and turn things around. And it does happen. Rarely. In fact, so infrequently, that in my opinion, the leader is better served operating with the parable of the scorpion and the frog in mind. In case you don't recall, the scorpion convinces the frog that he has changed and should the frog kindly agree to transporting the scorpion across the pond, the scorpion promises not to sting him. Needless to say, they don't make it across the pond. With their last gasps, the frog asks why and the scorpion responds with, "It's my nature."
