Nine-Box Team Grid

Are your people in the right places?

Assess your team on performance and potential, and get a clear map and a next move for every person.

The nine-box is the most widely used talent tool in the world, and the most abused. Done on a whiteboard with gut ratings and no follow-through, it becomes a labelling exercise that does more harm than good.

This version is built to be rigorous: anchored scales, evidence per placement, a check on assumed ambition, and a recommended move for every person. A leader's private thinking aid, not a verdict.

What good looks like

At its best, the nine-box is a conversation.

You carry a rough map of your team in your head. Who is flying, who is coasting, who could do far more than their role asks of them. But it lives on instinct, it shifts with the day, and you have never really tested it.

Done properly, that map gets tested. Each person weighed on their own merits, with a reason you can say out loud for where they sit, so you can see who is ready to rise and has the appetite for it, and who is thriving right where they are. You come away with a picture of the team you can stand behind.

That's really what the grid is for: a prompt for the honest, evidenced discussion you would otherwise keep putting off. The real value shows up afterwards, when everyone leaves with a clear next step and someone owning it. And because it is only a snapshot of today, you revisit it as people grow, which is usually when the interesting shifts happen.

What gets measured

Two axes, nine boxes.

Every person is placed on two anchored scales, and where the two readings meet is their box. Potential is the half people get wrong, so it is defined rather than assumed.

Performance
What they deliver against what the role demands. Rated on evidence: goal completion, quality, stakeholder feedback, and a full-year pattern rather than the last few weeks.
Potential
Whether they could take on more, read as a composite of aspiration, ability to learn and apply, and engagement. A separate question from doing today's job well, and the most bias-prone rating in the grid.
Rough Diamond
Real capability blocked by role fit, unclear expectations or circumstances. Blocked, rather than incapable.
Future Star
High potential meeting the bar, often six to twelve months from Star. The task is proving it out.
Star
Delivering strongly with the potential to go much further. The risk is losing them if momentum stalls.
Inconsistent Player
Reasonable potential, but performance has dipped. Worth a close, honest look at why.
Core Player
The largest segment in most teams. Reliable and competent, the stable core the team runs on.
High Performer
The operational backbone. Strong, reliable delivery, possibly at their ceiling for scope. A flight risk if overlooked.
Underperformer
Not meeting the bar, with limited readiness to grow. The clearest action, and the costliest to leave undone.
Solid Contributor
Reliable and competent, and likely to plateau. Valuable exactly as they are.
Trusted Professional
A deep specialist delivering strongly, with limited appetite for broader roles. Promoting them out loses their value.
How it works

Three steps, your own private thinking aid.

The process is designed to replace gut ratings. You place each person against defined scales for performance and potential, backed by a specific example and a prompt to check if you've had a real developmental conversation.

  1. 1
    Place your people
    Rate each person on two anchored scales, with an example. Up to 6, free.
  2. 2
    Get the grid
    It comes back the moment you finish, with a headline move for everyone.
  3. 3
    Work it privately
    Use it as a thinking aid for you as the leader. The label is a working note for you. What people should hear is the next step, and why.
How potential is rated

What is this person's capacity and desire to grow into a role of greater scope, complexity or impact?

1 · At capacity
2 · Emerging
3 · Growth potential
Clear signals across all three markers: genuine aspiration to take on more, ability to learn quickly and apply lessons to new situations, and engagement to stay and stretch. Ready for more scope in 12 to 24 months.
4 · Strong, rounded
5 · Ready to stretch
Evidence, required
One specific example from the last six months, rather than a general impression.
Have you actually asked what they want?
Assuming aspiration is the most common and costly error in the grid, so the tool makes you confirm it.
What you get back

Every person placed, with a move.

Three of your team sit in the same box. Your bench is thinner than it looks, and one of them is a flight risk.

The evidence

Fifty years on, it still earns its place.

The nine-box grid is a simple but powerful talent-management tool. It plots employees on a 3x3 matrix, with current performance on one axis, future potential on the other, producing nine boxes that each suggest a clear development or succession action. It traces back to the GE-McKinsey nine-box matrix that McKinsey built for General Electric in the early 1970s to prioritise investment across its business units, and HR later adapted the same logic to people.

Used well, its value is substantial. It gives leaders a shared language and a consistent standard for talent reviews, turning ad-hoc, single-manager judgements into structured, evidence-based discussions. It systematically identifies high-potential talent and ready-now successors, strengthening the leadership pipeline and reducing reliance on costly external hires. It focuses finite development budgets where they generate the most return, with tailored actions for each box.

By separating performance from potential, it counters the classic error of assuming today's strong performer is tomorrow's leader. And where ratings are calibrated across managers rather than left to one, they become measurably more consistent from one manager to the next. Its visual simplicity means an entire team's talent landscape can be understood at a glance, which is why the tool has endured for over fifty years.

The key is execution: clear criteria, multiple data sources, honest calibration, and real follow-through. As practitioners put it, “it's not about the boxes”, it's about the quality of the conversation the grid enables.

Questions leaders ask

The things worth checking before you start.

What makes the nine-box worth using?

It does something few talent tools manage: it separates how someone is performing now from how far they could go, and puts a whole team on a single page. It has been in use since the early 1970s, and it is still what most talent reviews reach for.

What makes this version rigorous?

Both scales are anchored, so you rate against defined levels rather than a feeling. Every placement asks for a specific example. Potential is defined as a composite of aspiration, ability and engagement, and the tool makes you confirm you have actually asked what someone wants. You come away with a move for every person and a guide for running the conversation.

Will anyone see how I have placed them?

Not unless you show them. The grid is private to you: nothing is sent to the people you place, and the tool never shows anyone their own box. What you share afterwards is your call. Most leaders give someone the next step rather than the rating behind it.

What do I actually get for each person?

A summary of where they sit and a specific next move, grounded in what their box really means. It is built to open a development conversation.

What happens to my data?

It stays yours. Your placements are private to you and never shared with the people you plot. Ask us to delete everything and we will.

What is the team coach debrief?

A 30-minute one-to-one session included in the price of Grid, Pro, worth £95. You run the grid first, then work through it with a team coach: where the pattern is thin, who to move, and how to have the conversation. The session is for you as the leader.
