The 9-box grid is a talent-review tool that places each employee on a three-by-three matrix: current performance on one axis and potential for larger roles on the other. Leaders use it in talent reviews to agree who is ready for promotion, who needs development, and who may be in the wrong role, and to plan succession for key positions. It is one of the most widely used tools in talent management, and one of the most criticised, because the potential axis rests on judgment that is hard to make consistent.
How the grid works
Each person is rated low, medium or high on two dimensions:
- Performance: results and behaviour in the current role, usually over the last year or two. This is the axis with evidence behind it: goals met, ratings, feedback.
- Potential: the capacity to grow into a bigger or broader role within a defined time, often two to three years. This is a forecast, not a measurement.
| Low performance | Medium performance | High performance | |
|---|---|---|---|
| High potential | Rough diamond: capable but not yet delivering; check fit and support | Emerging star: growing into the role; stretch them | Star: ready for a bigger role now; plan the move |
| Medium potential | Inconsistent player: diagnose why | Core player: the backbone; keep engaged | High performer: develop and broaden |
| Low potential | Under-performer: improve, move or exit | Effective in role: may have found their level | Trusted professional: expert in the current role; retain |
The names vary between companies. What matters is that each box leads to a decision: a move, a development plan, a retention action or a performance conversation.
Where the grid came from
The grid is usually traced to the business-portfolio matrix that McKinsey developed with General Electric in the early 1970s, which rated business units on industry attractiveness and competitive strength in a three-by-three grid. HR teams adapted the format for people. There is no single published origin for the people version, so treat confident claims about who invented it with caution.
How to run a 9-box talent review
- Define potential before the meeting. Write down what "high potential" means here: ready for which roles, within what time. Without this, each leader uses their own definition.
- Rate performance first, with evidence. Use the existing performance data; do not let a potential judgment colour it.
- Pre-place, then calibrate. Managers place their people in advance; the meeting is for challenging placements across teams, not for filling the grid.
- Challenge every high-potential placement. Ask for examples of the person handling more scope, ambiguity or complexity, not just doing the current job well.
- Agree an action for every box. A placement without a decision is wasted time.
- Check the distribution. Look at who lands in each box by gender, age, nationality and manager. Patterns that follow demographics rather than evidence are a warning.
- Keep it confidential, but tell people the action. Most companies do not tell employees their box; they do tell them about the development or move it led to.
Where it goes wrong
- Potential is mistaken for performance. Strong performers are assumed to have high potential; the grid's two axes collapse into one.
- Potential is mistaken for similarity. People who look, talk and work like the current leaders are rated as having potential. This is where bias enters most often.
- Labels stick. A person placed low on potential once may stay there for years.
- Managers game it. Some managers rate their best people low to keep them; others rate everyone high.
- It becomes the goal. Time goes into debating boxes instead of into the moves and development the review was meant to produce.
Some companies have moved to simpler questions, such as "ready now for which role?" or a skills-based view of readiness. Most still use the grid, with tighter definitions of potential.
The 9-box in Japan
Japanese companies traditionally identified future leaders through long observation, rotation and seniority, with selection for management coming late, often in a person's forties. Formal talent reviews with a 9-box arrived with foreign companies and with Japanese groups building global succession plans. The challenge in Japan is the potential axis: in a culture that values modesty and consistency, ambition and visible stretch are less often displayed, and assessors need clearer definitions to avoid rewarding the people who promote themselves.

Questions
What is the 9-box grid?
A three-by-three matrix that places employees by current performance and potential for larger roles, used in talent reviews to plan development, promotion and succession.
What do the nine boxes mean?
Each combination of low, medium and high performance and potential suggests an action. High performance and high potential usually means ready for a bigger role; low on both means a performance conversation or exit; the middle box is the core of the workforce. Box names vary by company.
How is potential measured in the 9-box?
It is a judgment, ideally against a written definition: readiness for specific larger roles within a set time, backed by examples of handling more scope or complexity. Some companies add assessments or structured interviews to make it more consistent.
Should employees be told their 9-box placement?
Most companies do not share the box itself, because labels can demotivate and are hard to change. They do share the outcome: a development plan, a stretch assignment or a move.
