What is the 9-Box Grid model? How to evaluate personnel using performance data and budget.

The 9-Box Grid model is not just a "Performance × Potential" matrix for classifying employees, but a tool that helps CEOs/CHROs/CFOs make decisions about development, succession, retention, rotation, and performance improvement based on data. 

This article by Bizzi will explain the nature of the 9-box grid model, how to build performance/potential measurement criteria to avoid subjectivity, the calibration process to reduce bias, and how to translate 9-box results into personnel costsTraining ROI/retention cost. It also suggests a digitalization roadmap using operational data for faster decision-making.

What is the 9-Box Grid model and how is it used for decision-making?

The 9-Box Grid is a performance and potential-based employee evaluation matrix that helps businesses categorize talent to make systematic decisions about development, succession, retention, rotation, or PIP (Project-Investment Planning).

The 9-Box Grid model is a human resource management tool used to evaluate and classify personnel based on two main axes:

How is the 9-Box Grid used for decision-making?

The primary goal of the 9-Box Grid is to help leaders make the right decisions about developing, retaining, rotating, or replacing personnel, especially in key person roles and succession planning.

Training & Development Decisions

Succession and Promotion Decisions

Decision to retain staff

Decision to rotate or improve performance

Decision to replace or remove

The primary goal of the 9-Box Grid is to help leaders make the right decisions about developing, retaining, rotating, or replacing personnel, especially in key person roles and succession planning.

How does the 9-Box Grid categorize personnel along the Performance and Potential axes?

The 9-Box Grid uses two axes: Performance reflects the results of achieving goals; Potential reflects the ability to take on a larger role in the future. Combining the two axes creates 9 different action groups, from "star/HighPo" to "needs improvement".

The model is a 3×3 = 9-cell matrix, with:

Vertical axis – Performance

Horizontal axis – Potential

 Each employee will be placed in one of nine cells. The meaning of each group in the 9-Box Grid.

Box Characteristic Common way of calling
1. Low Performance – Low Potential Poor performance, limited growth potential. Underformer
2. Medium Performance – Low Potential Stable job, difficult to break through. Draw propose
3. High Performance – Low Potential Highly skilled in their field but find it difficult to advance to management positions. Expert / Specialist
4. Low Performance – Medium Potential Not yet met KPIs, but has potential. Unpolished talent
5. Medium Performance – Medium Potential Key personnel Core salary
6. High Performance – Medium Potential If you do well, you may be promoted to a higher role. Emerging leader
7. Low Performance – High Potential Not performing well, needs training. High potential – low delivery
8. Medium Performance – High Potential Potential successors Dual leader
9. High Performance – High Potential Strategic talent Hi-Po / Top Talent

The 9-Box Grid uses two axes: Performance reflects the results of achieving goals; Potential reflects the ability to take on a larger role in the future.

What performance metrics should be used in a 9-Box Grid to gain the CFO's trust?

Performance must be measurable, verifiable, traceable, and comparable. It shouldn't be based on subjective feelings or "assessments for the sake of appearances." Below is a standard CFO-grade performance index framework, used by many businesses when linking the 9-Box Grid to compensation, benefits, and human resource budget decisions.

(A) KPI/OKR results – obligatory

Role type CFO Trust Index
Sales % achieved revenue, Gross Margin, and DSO.
Marketing Campaign ROI, CAC, Revenue attributed
Finance Closing cycle, Error rate, Cash forecast accuracy
Ops / SCM Inventory turnover, OTD, Cost saving
HR Cost/Headcount, Attrition key role
Brand / Beauty Sell-out, GM%, inventory aging

Scoring method (example):

(B) Execution quality & risk – The CFO is very interested.

Index Meaning
Error rate Errors, rework, claim
Deadline Late payments impact cash flow.
compliance Procedure violations, audit
Cost variance Budget deficit

Employees meet KPIs but pose risks → Performance cannot be ranked highly.

(C) Execution behavior (measurable)

Don't measure "attitude," only measure consequential behavior:

Index How to measure
Employment % tasks completed without reminder
Cross-function impact Number of interdepartmental projects
Improvement initiative Cost-saving/efficiency improvement initiatives
Manager feedback There's a form, no verbal feedback.

What criteria should be used to measure the Potential axis in a 9-Box Grid to avoid becoming a mere "feeling"?

If Performance is a number, then Potential must be a number. The probability of generating higher performance in the future. – not just a feeling of "having the aptitude." To prevent the Potential axis from becoming subjective, it needs to be measured by predictable future behavior with repeatable evidence. 

Potential should be based on evidence of competence, leadership behavior, and learning agility, linked to the level of readiness for succession. Potential doesn't mean "currently excellent," but rather "capable of handling greater responsibilities."

(1) Learning Agility – speed of learning & adaptation (required)

Measurement question Observation signs
Is it a quick learning process? Fast onboarding, requires little instruction.
Is this applicable? Transform new knowledge into results.
Is the change of setting a good one? Able to work outside the original scope

Not measured by feeling, measured by:

(2) Ability to Handle Complexity – carrying complexity

Level For example
Task Perform assigned tasks.
Project Managing multiple tasks
System Understanding cross-function effects
Strategic Trade-off decision

High potential = able to handle more variables, not just faster.

(3) Leadership Behaviors (including those not yet managers)

Don't measure "leadership qualities," measure behavior:

Behavior How to prove it
Employment Take the initiative to take on challenging tasks.
Image Others listen and follow.
Decision-making Dare to make decisions in the face of data scarcity.
Talent lift Help others do better.

(4) Motivation & Career Aspiration – Sustainable Motivation

Potential doesn't exist without motivation.

Measured by:

CFOs hate making mistakes: Highly capable but unwilling to take on extra responsibility..

(5) Value & Risk Alignment – the level of “safety when empowering”

Token Meaning
Follow Don't break the process.
Judgment Don't trade risk for KPIs.
Trust theory Assigned a sensitive task.

High potential but high risk → should not be placed in the top box.

What personnel groups and priority actions do the 9 cells in the 9-Box Grid represent?

The 9-Box Grid isn't about "ranking people," but about answering three crucial survival questions:

Below is how to group the 9 cells of the 9-Box Grid into 3 high-level clusters (Star / Core / Underperformer), along with naming conventions that are "different enough to avoid clichés" but still easily recognizable, and prioritizing actions in line with leadership and CFO principles.

STAR / Hi-Po cluster (High Potential ± High Performance)

(Box 8 – 9 – part of Box 6)

Box Suggested names Feature Priority action
9 (HP–HP) Star High performance + ability to take on a bigger role Succession plan, fast-track, retention package
8 (MP–HP) Future Maker Not yet a top performer, but clearly has leadership potential. Stretch assignment, C-level mentor
6 (HP–MP) Rising Leader Well done, ready to expand the scope. Cross-departmental project, trying out the lead role.

Strategy

CORE unit (operational backbone)

(Box 3 – 5 – part of Box 2)

Box Suggested names Feature Priority action
5 (MP–MP) Key Contributor Core, stable personnel Retention, clear career path.
3 (HP–LP) Expert / Specialist Highly skilled in their field, but doesn't want a management position. Compensation based on depth, no pressure to find leads.
2 (MP–LP) Workhorse Do things consistently, with few breakthroughs. Optimizing processes, standardizing work.

Strategy

UNDERPERFORMER cluster (decision-making area)

(Box 1 – 4 – 7)

Box Suggested names Feature Priority action
7 (LP–HP) Dilemma They have the potential but haven't achieved results yet. Coaching + testing for 3-6 months
4 (LP–MP) Unpolished Not suitable for the current location. Rotation or retraining
1 (LP–LP) Underformer Ineffective, no potential. PIP → exit if no improvement

Strategy

What steps are involved in the 9-Box Grid implementation process with a review cycle to avoid bias?

To implement a 9-Box Grid with a review cycle without turning into a “feel-out meeting,” the process must be designed as a decision-making pipeline with anti-bias checkpoints at each step.

Below is a standard 7-step process, currently being adopted by many businesses when linking the 9-Box to rewards, succession planning, and human resource budgeting.

Step 1: Standardize criteria (Before the evaluation)

Objective: Block halo effect from the beginning

What to do

Step 2: Collect independent data

Objective: To separate data from reviewers.

Data sources

HR/Finance prepares the data; line managers do not provide the numbers themselves.

Step 3: Individual Scoring

Objective: To avoid the “meeting room effect”.

Making

Do not show other people's reviews at this stage.

Step 4: Evidence Review

Objective: Eliminate subjective feelings before arranging the boxes.

Required question

HR plays the role of "bias police," not secretary.

Step 5: Calibration Meeting (Most important)

Objective: To ensure fairness and consistency.

Ingredient

The Golden Rule

 "If this person were on a different team, would the outcome be different?"

CFOs typically require:

STEP 6. Link the decision and the action.

Objective: The 9-Box creates actions, not slides.

Mapping is required.

Box Decision
Star Success, retention
core Development plan
Dilemma 3–6 months test
Underformer PIP / Exit

STEP 7. Follow-up & Post-review

Objective: To verify the accuracy of Potential.

What to do

Potential is only true when tested over time.

How should an action playbook with a 9-Box Grid be designed to generate employee ROI?

The 9-Box approach only generates ROI when each box is accompanied by a financial decision. For the 9-Box Grid action playbook to truly generate human resource ROI, the mindset must shift from: "Each box represents a unique investment and return on investment problem."

Below is the Action Playbook, organized into 9-Box groups, designed according to CFO logic: How much to invest – what are the expected returns – how to measure them?.

STAR / Hi-Po – Future Growth

(Box 9 – 8 – 6)

ROI objectives

Priority action: 

Action Target Expected ROI
stretch A real skills test Probability of succession increases.
Strategic project Create impact over/cost leverage
C-level Mentor Accelerate growth Role availability time ↓
Retention package Retain people Replacement cost ↓

CORE – Optimize current performance

(Box 5 – 3 – 2)

ROI objectives

Priority Action

Action Target Expected ROI
Skill deepening Increase productivity Output/FTE ↑
Process Reduce waste Cost saving
Career clarity Retain Attitude ↓
Recognition targeted Increase engagement Sustainable performance

UNDERPERFORMER – Stop loss or reversal

(Box 7 – 4 – 1)

ROI objectives

 Priority Action

Action Target Expected ROI
Coaching has deadlines. Rapid test Recovery / Exit
Role re-fit The right person for the right job. Performance ↑
PIP A decisive decision Cost leak ↓
Controlled Exit Reduce losses Team morale ↑

How does the 9-Box Grid link with HR and FP&A budgets to forecast payroll and development costs?

The 9-Box isn't just for "assessing people," but to answer this question: "Where should the money be invested – who should we retain – who should we develop – where should we recruit new players?"

Main budget lines:

A. High Performance – High Potential

Target

Budget allocation

B. High Performance – Medium Potential

Target

Budget allocation

C. Medium Performance – High Potential

Target

Budget allocation

D. Medium / Low Performance – Medium / Low Potential

Target

Budget allocation

E. Low Performance – Low Potential

Target

Budget allocation

How do employee positions on the 9-Box Grid relate to OpEx and cash flow (CFO's perspective)?

The 9-box model impacts OpEx and cash flow through HR decisions: retention, training, new hires, and performance improvement. When performance is measured by operational and financial data, CFOs can identify which teams create value, which create “hidden costs,” and prioritize investments accordingly.

Below is a breakdown of each 9-Box group from the OpEx & Cash Flow perspective.

Opera Cash Flow
A. High Performance – High Potential High payroll → Increased opEx

But the cost per unit of value generated is low.

Increase:

  • Revenue (decision quality, speed)
  • Operational efficiency → reduced working capital lock

Reduce:

  • Recruitment costs
  • Mis-decision costs
B. High Performance – Medium Potential Payroll is stable.

Training focuses on professional skills.

Stable and predictable cash flow.

Low risk of volatility

C. Medium Performance – High Potential Training and mentoring increase → OpEx increases first.

ROI is not yet recognized.

Short term:
→ Negative or neutral

Medium to long term:
→ Reduce external recruitment
→ Create an internal pipeline

D. Medium / Low Performance – Medium / Low Potential Payroll accounts for a large proportion of the total.

Raising wages doesn't create more output.

Neutral or negative cash flow

Prone to occurring:

  • Operational error
  • Inventory
  • Bad debts
E. Low Performance – Low Potential Payroll = sunk cost

Training = a waste of time.

Minus:
  • Delayed
  • Process error
  • Increased control costs

What are the legal risks and compensation costs associated with using a 9-Box Grid to handle underformers?

The 9-box is merely a grouping tool; using it for "ranking and yanking" or improper dismissals can lead to disputes, compensation costs, and damage to the employer brand. 

From a CFO + Risk Management perspective, the 9-Box Grid is only safe when accompanied by evidence mechanisms. If the 9-Box is used to handle underperformers without proper control, the business will not only "lose people" but also "lose money and face lawsuits".

Legal risks and compensation costs when dealing with underformers.

RISK 1 – Lack of Performance Evidence (Evidence Gap)

Risk mechanism

Employees can sue for:

Costs may arise.

B. RISK 2 – Lack of a Plan for Improvement (No PIP / No Fair Chance)

Risk mechanism

Legally: Courts usually side with workers if they are not given "opportunities for improvement."

Hidden costs

C. RISK 3 – Lack of calibration record (Governance Failure)

Risk mechanism

Employees can sue for:

Indirect costs

In short, the 9-Box helps you assess people, but only the records and processes protect your finances.

In short, the 9-Box isn't based on management's intuition, but on whether "this employee is generating, retaining, or leaking cash flow."

What are the advantages and disadvantages of the 9-Box Grid model?

The 9-box system helps standardize personnel decisions and development/succession priorities, but it can be flawed if criteria are vague, data is lacking, and calibration is insufficient. Businesses should not use the 9-box system as a tool for "mass dismissal" or as a replacement for proper performance management.

What are the advantages of the 9-Box Grid model? 

  1. Clearly define talent segments (Talent Segmentation)
  1. Resource Prioritization
  1. Support succession & workforce planning
  1. Common language between HR – Line – Finance

Frequently Asked Questions about the 9-Box Grid Model (FAQ)

Below is a compilation of frequently asked questions about the 9-Box Grid model, along with detailed answers.

Is a 9-Box Grid suitable for small and medium-sized businesses?

Yes, if implemented appropriately to the organization's level of maturity.

For SMEs, the value of the 9-Box lies in the action, not in the sophistication of the framework.

How can we convert "Potential" data into payroll forecasting data in FP&A?

Potential is not directly included in the budget, but must be translated into a personnel scenario.

The standard method:

  1. Potential → readiness (level of readiness to take on a higher role)
  2. Develop scenario planning in teams:
    • HiPo / Star: Promotion prospects, development programs, retention packages
    • Core: Salary increase in line with market rates.
  3. Integrate these scenarios into the payroll forecasting model.
  4. Monitor Plan vs Actual to adjust assumptions.

CFOs don't "believe" in potential; CFOs believe in scenarios and probabilities.

What are the hidden costs of hiring a "medium-performing, low-potential" group compared to hiring new employees?

Don't compare based on emotions, but compare the total cost over the product's lifecycle. Compare both sides:

(1) Retention cost:

(2) Replacement cost:

The comparison results are used to make a decision:

How can we use Expense Management data to assess “compliance & performance” in the 9-box?

Expense data is a very good source of evidence for the Performance axis.

The following metrics can be used:

This data helps to:

This data source is particularly well-suited for managerial roles.

What is the connection between the 9-box of Sales and DSO?

For sales, performance isn't just about sales figures, but about the quality of revenue generated.

By linking 9-Box to DSO, the CFO can clearly see who is generating "real money" revenue.

How should training ROI be measured to avoid "scattered training"?

Instead of measuring ROI across the entire training program, it's measured by 9-Box groups.

Recommended measurement framework: Benefit – Cost

Investment priorities:

How many laps are needed for calibration, and who should participate?

It doesn't take many rounds, just the right people and the right method.

Minimum requirements:

Principle:

Calibration is a mechanism for reducing governance bias and risks, not a mere formality.

How is a 9-box grid different from forced ranking?

Using 9-Box ranking increases labeling risk and disrupts internal fairness.

What support does Bizzi Bot/Expense/ARM offer to 9-box systems if businesses want to "quantify" performance?

These solutions provide real-time data to reduce subjectivity when stacking 9-Boxes:

All of this creates evidence-based assessment for the Performance axis.

Bizzi Bot automatically performs intelligent 3-way verification of invoices, purchase orders, and warehouse receipts.

Conclude

The 9-Box Grid model is not a "human evaluation matrix," but rather a decision-making tool that helps businesses answer three core questions:

  1. Who is creating, holding, or leaking value?
  2. Where should resources (salaries, training, retention) be prioritized?
  3. Who will be the successors to protect future growth and cash flow?

When implemented correctly, the 9-Box model becomes a bridge between human resource strategy and financial strategy. When combined with solutions like Bizzi, businesses can:
