[Excerpt] Managers, who account for 70% of the variance in employee engagement and are the reason for 75% of voluntary turnover, have significant fiscal impact. Therefore, an organization’s ability to identify, develop, and retain leaders is a critical competitive advantage. It is estimated that companies with capable leaders achieve, on average, 147% higher earnings per share than competitors, and, that negative employee-supervisor relationships cost some $360 billion per year in lost productivity. This summary will outline the characteristics of successful people managers, and will provide recommendations for identification processes that better predict performance.
