David Lee, Executive Director of the MSS Business Transformation Institute, uses Mozart in the Jungle to explain the study in the evolution of the leaders from the previous conductor dealing with a new reality to the new conductor trying to reach his potential as well as the potential of the organization he is leading. Looking at what it takes to be a leader in today’s exponentially changing environment, leaders must also look at the evolution of leadership. Lee covers a brief history of organizational development and the evolution of leadership theory, and how it relates to being a conductor of a symphony. Lee uses studies about command and control environments and how they affect productivity short-term and long-term. Ultimately, leaders account for at least 70% of variance in employee engagement scores. Lee highlights his personal stories of working with two different leaders and analyzes who would be a better fit for business in today’s complex world.
