Talent differentiation / succession
9-Box Grid (Performance × Potential)
The 9-box plots people on two axes, current performance and future potential, to produce nine segments that support different talent decisions for different people.
It started as a GE and McKinsey tool for ranking business units, and became the standard structure for talent review meetings.

Theory & origin
The nine-box grew out of GE and McKinsey's 1970s work on managing a portfolio of businesses, later repurposed to rank people instead of business units. Plotting current performance against future potential forces a leadership team to say, out loud, who the future stars are and who has plateaued. A single performance rating never forces that conversation. The tool's staying power comes from that forced conversation, not from any statistical rigor in the axes themselves.

How a consultant runs it
- 01 Before the meeting, get the client to agree on an observable definition of 'potential' (learning agility, aspiration, capacity), so the vertical axis is not just tenure in disguise.
- 02 Have managers pre-populate placements, then run a calibration session where every placement has to be defended with evidence.
- 03 Read the grid at portfolio level: which critical functions have no ready successors, where is talent concentrated, and who is a flight risk?
- 04 Give every box its own action: stretch, retain, develop, or manage out, each with an owner and a date.
- 05 Keep placements confidential. They are hypotheses for investment decisions, not labels to hand to employees.
When to use
- 01 Talent review or succession planning cycles with a leadership team
- 02 Forcing a differentiated conversation instead of "everyone is doing fine"
- 03 Spotting portfolio-level patterns, like a critical function with no future stars in it
When not to use
- 01 As a performance rating communicated to employees. It is a calibration tool, not a scorecard.
- 02 When "potential" has no agreed definition. Without one, the vertical axis is basically astrology.
- 03 For small teams, under about 8 people, where portfolio logic adds nothing over a direct conversation
Worked example
A talent review of 24 senior managers places 11 in Core, 4 in Trusted Professional, and 3 in Future Star, all three in the same product division. The real insight only shows up at portfolio level: two divisions have zero succession coverage.
The actions that follow: targeted stretch moves across divisions, plus a workshop to properly define "potential," because two markets had quietly been rating potential as tenure.
Common pitfalls
- 01 Leaving "potential" undefined. Agree on observable indicators, like learning agility, aspiration and capacity, before the meeting.
- 02 Letting box positions leak to employees as labels. Treat placements as confidential hypotheses, not verdicts.
- 03 Recency bias: last quarter's result moving someone two boxes
- 04 Doing the grid and skipping the actions. Every placement needs a next step with an owner.
