The 9-box grid

Each cell in the grid carries a label and a recommended action. The action determines what happens next: accelerate, develop, coach, or exit. The labels below reflect how Huneety categorizes talent in succession planning projects.

High potential row

Star or Successor (high performance, high potential): retain and promote. These are your succession pipeline candidates. Give them stretch assignments, executive exposure, and accelerated development.

Future Star (meets performance, high potential): accelerate development. The ceiling is high but they are not yet delivering at the top. Invest in targeted skill building.

Enigma (low performance, high potential): investigate and decide. The potential is there but something is blocking performance. It could be the wrong role, a mismatched manager, or personal circumstances. Diagnose before acting.

Medium potential row

High Performer (high performance, medium potential): stretch and reward. Delivering strong results. May not move into executive roles but can take on lateral complexity. Risk of leaving if undervalued.

Core Player (meets performance, medium potential): develop and engage. The backbone of the organization. Provide targeted development, not neglect.

Risk (low performance, medium potential): coach or reassign. Not delivering in the current role. Coaching window is 6 to 12 months, then reassess.

Low potential row

Solid Professional (high performance, low potential): deepen expertise. Excellent in their current role. Do not over-promote. Recognize and reward their contribution where they are.

Underachiever (meets performance, low potential): performance plan. Below expectations with limited growth trajectory. Structured improvement plan with clear milestones.

Action Required (low performance, low potential): exit plan. Neither performing nor growing. Managed exit, done respectfully.

The biggest mistake organizations make with the 9-box grid is handing a blank version to managers and asking them to rank their people. That produces grade inflation, not talent intelligence. The grid is an output of a data-driven process, not a worksheet.

Pre-populate the grid with PMS and 360 data before anyone sees it. Two data sources feed the grid, and both should be collected before the first calibration meeting.

The performance axis (x) is sourced from the Performance Management System. KPI achievement and competency ratings from the most recent assessment cycle. This is backward-looking: what did this person deliver? This data already exists in most organizations.

The potential axis (y) is sourced from behavioral data, which is typically the output of the People Review. Role model behaviors (do peers and reports see leadership potential?) and learning agility (does this person grow when given new challenges?). This is forward-looking: where could this person go? 360 assessment data strengthens this axis significantly because it captures perception from multiple rater groups, not just one manager.

You can run a first-pass assumption round from PMS data alone to create an initial hypothesis. Plot everyone on the performance axis using hard data, and make preliminary potential estimates based on available signals. But this draft is an assumption, not a conclusion. It must be confirmed through the People Review before it is presented to the CEO or CHRO. The People Review adds the behavioral evidence that validates or challenges the potential placements.

Once placements are validated, each box maps to a development action. Stars and Future Stars enter the succession pipeline with accelerated individual development plans. Enigmas get diagnostic coaching. Core Players get targeted skill building. Action Required triggers a managed exit. The grid without development actions is a map with no route.

The 9-box grid is the output of the People Review, not a separate exercise. Without the People Review, the grid is just a spreadsheet with assumptions.

The People Review turns assumptions into evidence-backed placements. What it produces is behavioral data: the evidence layer that transforms PMS numbers into validated talent decisions. Managers propose their assessment of each person. Leadership challenges those proposals. HR provides supporting evidence from assessment data: 360 feedback themes, competency gap scores, historical trajectory. The result is confirmed behavioral data that populates the potential axis of the grid.

Who attends: the HR business partner and business unit leaders, typically one level above the talent pool being reviewed.

Pre-work: HR shares the assumption-round grid, pre-populated from PMS data. Leaders review and come prepared to discuss, challenge, and validate.

The discussion follows a structured format. Start with outliers: anyone where the PMS data and the behavioral evidence disagree. Review each segment, focusing on the top-right (succession candidates) and bottom-left (action required). Leadership challenges proposals with a simple standard: show the evidence. Not "I think" but "the data shows." HR provides context from 360 results, competency gap scores, and historical trajectory.

The output is the validated 9-box grid with confirmed placements (not assumptions) and specific development actions per person. This is what gets presented to the CEO and CHRO for strategic talent decisions. Each placement should map to a concrete next step: an individual development plan for high-potentials, a coaching engagement for enigmas, a performance improvement plan for underachievers.

The cardinal rule: do not give the 9-box to managers to rank their people directly. The 9-box is for the CEO and CHRO strategic review. Managers participate in the People Review, where their proposals are challenged with evidence. If every manager's team is 80% in the top-right, either you have the most extraordinary company in the world, or your managers are lying. The People Review exists to fix that.

Grade inflation: every manager puts their people in the top-right. The fix is simple: show the evidence. If the 360 data says "developing" and the manager says "star," one of them is wrong. The People Review is where this gap gets resolved.

Confusing tenure with potential: 15 years of experience does not equal high potential. Look for growth trajectory and learning agility, not stability and seniority. A person who has been in the same role for a decade without expanding their capability is not high-potential, regardless of their tenure.

Recency bias: placing talent based on last quarter rather than the full year of data. Use the complete assessment cycle, not a snapshot. One strong quarter does not make a successor. One bad quarter does not make a risk.

Popularity contest: "I like them" is not a placement criterion. Evidence or it does not count. 360 data from multiple rater groups is harder to game than a single manager's opinion, which is why multi-rater assessment strengthens the grid.

Static placements: the 9-box is a snapshot, not a life sentence. People move. Reassess every cycle. A Core Player this year could be a Future Star next year with the right development. Treating the grid as permanent discourages growth.

Using it in isolation: the 9-box without a People Review is just a spreadsheet exercise. Calibration is the point. The grid is the visual. The conversation is the value.
