The document discusses the nine box grid or matrix, a tool used in talent management to evaluate employees on two dimensions: leadership performance and leadership potential. The grid places employees into nine categories based on their combination of potential and performance. These categories include enigma, dilemma, underperformer, growth employee, core employee, effective, future leader, high impact performer, and trusted professional. The nine box grid can help identify development needs, facilitate succession planning, and optimize employee performance through retaining and grooming top talent. However, names in the boxes should be regularly reviewed as potential and performance can change over time.
