William Butler Yeats asked “how can one tell the dancer from the dance?” Great question. Leadership is not position or results. Leadership is identity and action. Leadership is not transaction and manipulation. Leadership is relationship. The quality of leadership is not dependant on outcomes, execution, or results. Better litmus tests would be the level of voluntary follower engagement, the extent of coordinated and convergent effort, or the increment of synergistic cooperation among followers. Managers love to measure and deconstruct things. Most managers are better measurers than they are leaders. For many managers, measurement is meaning, but for many others measurement has dangerously eclipsed meaning. It is threatening and irritating for those who depend on measurement for meaning and identity when they run into things that defy measurement. It is tempting and self-protective to say that those immeasurable things are not meaningful. This trap of measurement-dependent significance dilutes life. Regarding the measurement of leadership, I offer a contrary thought: to measure leadership is to dilute and confuse it. We would be tempted to say the same thing about love. We easily assume that we cannot measure the power and extent of love. At times, love, relationship, and even leadership seem to defy logic. Physicist Fritjof Capra said that it was impossible to measure a relationship. In fact, the ability to measure something does not dictate its reality (contrary to some managers’ assumptions). Love and relationship are more real than a quarter’s profits. Hence, an unhealthy obsession with measurement displaces the immeasurable value of unquantifiable things such as relationship, love, identity, and leadership. I believe that leadership cannot be measured effectively. And that’s OK. Somehow you will survive. Leadership is both who you are and what you do. So, who are you? And, what defines you?
