What is the McKinsey 9 box talent review?

The McKinsey 9 box talent review is a model originally developed by consultants at McKinsey & Company to help organizations identify leaders and plan for succession. It categorizes employees across nine boxes based on their current performance and potential to grow into more advanced roles. This method provides a structured way to make talent-related decisions and supports leadership development strategies by ensuring high performers and emerging talent are recognized, developed, and aligned with the company's long-term goals.
