The document discusses the 9-box model for classifying employees based on their performance and potential. The 9-box model assesses individuals on two dimensions: performance and potential. It places employees into nine categories within a grid based on their demonstrated performance and long-term potential. The categories range from "take action" for low performers to "consistent star" for top performers with highest potential. The model is meant to help identify high potentials, guide development plans, and consistently evaluate talent within an organization.
