Few decisions have greater consequences for an organization than the appointment of its leaders. The right leaders can elevate culture, accelerate innovation, and deliver sustainable results. The wrong ones destroy value, diminish trust, and push talented employees out the door. If you’ve ever worked under an incompetent boss, you don’t need the data to tell you how damaging bad leadership can be. But the data is unequivocal: poor leadership selection costs companies billions in disengagement, attrition, and underperformance. It is no exaggeration to say that leadership selection determines the fate of organizations and, by extension, societies. Whether in the corporate world, politics, or sport, getting it wrong is expensive. Getting it right is transformative.
