Tell me about a time when you used a specific metric to drive change in your department.

Focus on a specific metric that had a significant impact on your department's performance. Clearly articulate the context in which you identified the need for change and how the metric highlighted that need. Discuss whether you developed this metric yourself or utilized an existing one, and explain the rationale behind its selection. Detail the steps you took to implement the change based on the metric's insights, including any challenges faced and how you overcame them. Finally, quantify the results of the change to demonstrate its effectiveness.
