What is a Nine-Box Grid? Meaning and Example

Reading the nine boxes

Performance is usually taken from the latest appraisal. Potential is a judgement about a person's ability to grow into bigger roles, based on how fast they learn, how they handle new situations and how they lead. The four corners and the middle box carry the clearest messages:

• High performance, high potential: future leaders, so plan their next move
• High performance, low potential: strong experts to recognize and retain in their role
• Low performance, high potential: often new or in the wrong role, so coach or move them
• Low performance, low potential: address through an improvement plan or a role change
• Middle box: solid contributors who form the core of a team

Running a talent review with the grid

Managers place their team members before the meeting, then senior leaders and HR review the placements together, much like a calibration session. The discussion is what gives the grid its value: why is this person high potential, what evidence supports it, and what would move them up? The output is a list of actions, such as a stretch project for one person, a mentor for another, and a named successor for each critical role. Review the grid once a year and keep it confidential.

Limits of the nine-box grid

Potential is hard to judge and easy to bias. Managers tend to rate people like themselves, or the most visible, as high potential, while quiet performers in branches and on night shifts are missed. Labels also stick: a person placed low once may never be looked at again. Define potential in writing, ask for examples, and check the grid for patterns by gender, location and department before acting on it.
