Leadership is an organization’s most valuable resource. A great leader can impact an organization far more than any other resource. Leadership resources management (LRM) is a data-informed approach to strategically manage an organization’s leadership resources. It helps identify gaps in an individual leader’s practice of leadership, as well gaps in the perception of their leadership by their team. LRM replaces subjective interviews, relationship-based promotions and selections with a quantifiable, repeatable and unbiased leadership management strategy. When properly utilized, it helps the organization assign or promote the right person with the right leadership qualities to the right position at the right time. Through a case study, we will explore why a hospital system implemented LRM for the leadership team of their 5,000-person nursing unit, reveal the challenges faced in the implementation process and explore the findings the Chief Nursing Officer discovered in the results.
