What is the 9-Box Talent Review Grid?

When you’re running a growing company, one of the hardest things to figure out is who on your team should be promoted, who needs more development, and who might not be the right fit long-term. I’ve been in that situation more times than I can count. With over 100 hires across multiple SaaS companies, I’ve had to make tough calls about people, and I didn’t always get them right.

That’s why I started using the 9-box talent review grid. It gave me a visual, structured way to assess my team instead of relying on gut feelings. The framework isn’t perfect (I’ll get into the downsides later), but it’s one of the most useful tools I’ve found for talent management decisions.

In this article, I’ll walk you through how the 9 box grid works, how to fill one out, how to use it for succession planning and performance management, and the pros and cons based on my experience using it.

Alright, let’s break it down.

What is a 9 Box Talent Review Grid?

A 9-box talent review grid is a workforce planning tool that evaluates employees based on two dimensions: their current job performance and their future potential. The grid creates a 3×3 matrix with nine boxes, where each box represents a different combination of performance level (low, moderate, or high) and potential level (low, moderate, or high).

The concept was developed at McKinsey in the 1970s as a portfolio management framework and was later adapted by GE for talent management purposes. Since then, it has become one of the most used talent assessment tools in HR for succession planning and leadership development.

Here’s why I find it valuable. When you’re managing a team of 20, 50, or 100 people, it’s easy to lose track of who’s doing what. You might have someone who’s performing well in their current role but has no interest in growing further. You might also have someone who’s struggling right now but has enormous potential if given the right support. The 9 box grid helps you see all of this at a glance.

Organizations that take their talent management seriously tend to use this grid as part of regular talent review meetings, usually quarterly or annually. If you’re building out your HR strategy, understanding how this tool fits into the broader picture of talent management is essential.

How Does the 9 Box Grid Work?

The grid works by plotting employees on two axes. The horizontal axis measures current performance, which is how well the employee is executing in their current role. The vertical axis measures potential, which is the employee’s capacity to grow, take on more responsibility, and succeed in higher-level roles.

Each axis is divided into three levels: low, moderate, and high. This creates nine distinct boxes, and every employee gets placed into one of them based on their manager’s assessment (supported by data and multiple perspectives).

The top-right box (high performance, high potential) represents your stars. These are the people you want to invest in, give stretch assignments, and consider for succession into leadership roles. The bottom-left box (low performance, low potential) represents employees who may need to be managed out or transitioned into a different role.

Everything in between requires nuance. For example, someone in the high-performance-but-low-potential box is a solid contributor who’s great at their job but isn’t going to move into a leadership role. That’s fine, but you need to recognize it so you’re not setting them up for failure by promoting them into something they’re not suited for.

I think the grid works best when it’s used as a conversation starter rather than a final verdict. The real value comes from the discussions it forces. When I sit down with my leadership team and we map out where everyone falls, we always discover blind spots we didn’t see before.

1. Assess Employee Performance

The first step in filling out a 9-box grid is assessing each employee’s current performance. This should be based on objective criteria whenever possible. Look at goal completion, project outcomes, quality of work, reliability, and feedback from peers and managers.

I recommend against relying on one manager’s opinion. One of the biggest mistakes I’ve made in the past is trusting a single person’s assessment of someone’s performance without getting additional input. Different managers have different standards, and unconscious bias can creep in.

For employees with low performance, look at whether the issue is skill-related, motivation-related, or environment-related. Sometimes a person isn’t performing because they’re in the wrong role, not because they lack capability. I’ve moved people between teams before and watched their performance transform.

Moderate performers are hitting their targets but not exceeding them. They’re doing what’s expected but not going above and beyond. High performers are exceeding expectations, delivering quality work ahead of schedule, and impacting those around them. Tracking these distinctions through employee performance metrics gives you the data you need to make fair assessments.

2. Evaluate Employee Potential

Evaluating potential is harder than evaluating performance because potential is about the future. You’re trying to answer the question: could this person succeed in a role that’s bigger than their current one?

There are several signals I look for. Learning agility is a big one. Does this person pick up new skills? Do they adapt when the situation changes? Are they curious about areas outside their immediate job? Another signal is leadership behavior. Even if someone doesn’t have a manager title, do they step up, mentor others, and take ownership of problems?

Low-potential employees are content in their current role and don’t show interest or aptitude for significant growth. That doesn’t make them bad employees. Some of the most reliable people I’ve worked with were in this category, and they were essential to keeping things running well.

Moderate-potential employees can grow into the next level with the right development and support. High-potential employees have the capability and drive to advance. They’re the ones you build your succession plans around. Understanding where employees fall on this axis connects to how you think about the employee life cycle and where to invest your development resources.

3. Build the 3×3 Grid and Place Employees

Once you have performance and potential ratings for each employee, you map them onto the grid. Most companies do this during formal talent review meetings with HR leaders and department heads in the room.

I suggest doing this in collaboration, rather than having one person fill it out alone. When my team and I have done this together, we’ve caught disagreements that turned into productive conversations. One manager might rate someone as high potential while another sees them as moderate, and unpacking why reveals important context about the employee.

You can use something as simple as a spreadsheet or whiteboard for this. Some companies use dedicated HR analytics software, but the tool matters less than the quality of the discussion. The goal is to have a clear picture of your entire workforce so you can make informed decisions about promotions, development investments, and succession planning.

After placing everyone, look for patterns. Do you have too many people clustered in the middle? That might mean your rating criteria are too vague. Do you have very few high-potential employees? That could signal a development or hiring gap. These insights are what make the grid valuable.

How to Use the 9 Box Grid for Succession Planning

Succession planning is one of the most powerful applications of the 9-box grid. Once you’ve mapped your team, you can identify who’s ready (or just about ready) to step into critical roles if someone leaves or gets promoted.

Your high-performance, high-potential employees are your primary succession candidates. These are the people you should be grooming for leadership through stretch assignments, executive exposure, and formal development programs. When I was building my companies, identifying these individuals early was crucial. The last thing you want is your best performer leaving because they didn’t see a path forward.

Moderate-performance, high-potential employees are also worth watching. With the right coaching and development, they could become succession candidates within 12 to 18 months. The grid helps you create targeted development plans rather than taking a one-size-fits-all approach.

For strategic workforce planning purposes, the 9-box grid also helps you identify risk areas. If a critical role is held by someone with low potential and no obvious successor, that’s a vulnerability. You need to either develop internal candidates or start external recruiting before it becomes an emergency.

I’ve learned this the hard way. We lost a senior technical lead once and had nobody ready to step in. It took us three months to find a replacement, and during that time, the entire team’s output dropped. A proper succession plan built from 9-box data would have prevented that.

How to Use the 9 Box Grid for Performance Management

Beyond succession planning, the 9-box grid informs your performance management approach. Each box suggests a different management strategy.

For high performers with high potential (your stars), focus on accelerated development, visibility to senior leadership, and retention. These employees are your biggest flight risk because they have options. Make sure they feel valued and challenged. If you need a framework for recognizing these people, our guide on writing a performance improvement plan covers the flip side of performance conversations, which is also valuable context.

For high performers with low potential, focus on recognition and stability. These people are reliable, and you need them. Don’t try to force them into leadership roles they don’t want. Instead, deepen their expertise and find ways to reward their consistency.

Low performers with high potential are your development projects. These employees need clear feedback, a structured development plan, and a shift in their environment. Maybe they need a different manager, a different project, or additional training. The potential is there. You just need to unlock it.

Low performers with low potential require the hardest conversations. In some cases, a role change might help. In others, it may be time to part ways. I’ve had to make those calls, and they’re never easy, but delaying them hurts the rest of the team.

The grid gives you a common language for these conversations. Instead of vague statements like ‘I think they’re not a good fit,’ you can point to specific performance data and potential assessments. That makes the conversation more productive and less personal. Tracking the right HR KPIs helps ensure your ratings are grounded in data, not just opinions.

Benefits of the 9 Box Talent Review Grid

The biggest benefit of the 9-box grid is its simplicity. You don’t need fancy software or weeks of analysis. A leadership team can map its entire workforce in a few hours and walk away with actionable insights. That’s hard to beat.

It also promotes transparency. When everyone in the room is working from the same framework, the talent discussion becomes more objective and less political. I’ve seen organizations where promotion decisions were based on who had the loudest advocate. The 9-box grid shifts the conversation toward evidence.

Another benefit is that it creates alignment between HR and business leaders. When both sides are looking at the same grid, they can agree on where to invest development dollars, who should be in the succession pipeline, and where hiring gaps exist. This alignment is something you also get from building an effective HR scorecard, but the 9-box grid is more accessible for managers who aren’t steeped in HR metrics.

Last but not least, the grid helps with post-review action planning. Each box has a natural set of actions associated with it, which means you’re not just assessing people. You’re committing to the next steps.

Disadvantages of the 9 Box Talent Review Grid

I’d be dishonest if I didn’t mention the downsides, because there are some real ones.

The biggest issue is subjectivity. Potential is difficult to measure, and managers often disagree on what it looks like. Without clear criteria, the grid can become a reflection of bias rather than a true assessment of talent. I’ve seen situations where a manager’s personal preference for a certain communication style influenced their potential rating of someone very capable.

Another problem is that the grid can feel reductive. Putting a human being into one of nine boxes doesn’t capture the full picture of who they are. Context matters. Someone going through a tough personal situation might show low performance temporarily, but that doesn’t define their long-term capability.

There’s also a tendency for the grid to become static. Some organizations fill it out once a year and then forget about it. For it to be useful, it needs to be a living tool that gets updated as people grow, change roles, or face new challenges. If you’re using predictive analytics in HR, you can complement the grid with data-driven insights that make it more dynamic.

My recommendation is to use the 9 box grid as one input among many, not as the final word on anyone’s career. Combine it with regular one-on-ones, 360-degree feedback, and actual performance data to get a fuller picture.

Final Thoughts

The 9-box talent review grid isn’t perfect, but it’s one of the most practical tools I’ve found for making better people decisions. It forces you to think about your team in a structured way, surfaces blind spots, and creates a shared language for talent discussions.

If you’re leading a growing company or managing a team, I’d encourage you to try it. Start simple with a whiteboard or spreadsheet, get your leadership team in the room, and have an honest conversation about where each person falls. The insights you walk away with will be worth the time investment, and your team will be stronger for it.

FAQ

Here, I answer the most frequently asked questions about the 9-box talent review grid.

What is a 9-box grid used for in HR?

A 9-box grid is used to assess employees based on their current performance and future potential. HR teams use it for succession planning, identifying high-potential talent, making promotion decisions, and creating targeted development plans. It gives organizations a visual snapshot of their workforce.

How often should you update a 9-box grid?

I recommend updating it at least twice a year for fast-growing teams. Annual reviews aren’t frequent enough because people change roles, develop new skills, and face different challenges throughout the year. A static grid has a tendency to become outdated.

Who should participate in filling out the 9-box grid?

Talent reviews should involve direct managers, senior leaders, and HR business partners. Having multiple perspectives reduces individual bias and produces more accurate assessments. I’ve found that the most productive sessions include at least three people who work with the employees being reviewed.

What happens to employees in the low-performance, low-potential box?

These employees need direct conversations about performance expectations. In some cases, a role change or additional support resolves the issue. In others, it may lead to a managed exit. The key is to act quickly and fairly rather than avoiding the conversation.

Can the 9-box grid be biased?

Yes, it can. Potential is subjective, and managers may favor employees who are similar to them in background or communication style. To reduce bias, use clear rating criteria, include multiple evaluators in the process, and supplement the grid with objective performance data.

Is the 9-box grid the same as a performance review?

No. A performance review evaluates how well an employee performed over a specific period. The 9 box grid evaluates both performance and future potential, and it’s used at an organizational level rather than for individual feedback. Think of the grid as a strategic workforce planning tool, and the performance review as a personal development tool.
