The McKinsey 9-Box Model is a framework used to evaluate the potential of an individual employee for future leadership roles within an organization. The model assesses an employee’s potential along two dimensions: performance and potential. Performance refers to an employee’s current job performance, while potential refers to an employee’s potential for advancement and leadership. The model uses a 9-box grid, with performance on one axis and potential on the other, to create nine different categories of employees. These categories range from high-potential, high-performing employees (who are considered the most valuable) to low-potential, low-performing employees (who are considered the least valuable).
