Top UK employers are ditching the nine-box.
But most aren't replacing it entirely. They're using the Success Circle alongside it, and the difference matters more than you'd think.
I developed the Success Circle four years ago and I've seen organizations wrestle with this question constantly: do we abandon the Nine-Box Grid completely or keep it?
The answer isn't either/or.
Here's the fundamental issue with the Nine-Box Grid that nobody talks about enough. You can't show it to your employees. Not really. Because the moment someone sees they're not in that top-right "high performer, high potential" box, it becomes demotivating rather than developmental. So the tool that's supposed to help people grow their careers... has to be kept secret from them.
That's backwards.
The Nine-Box has been around since McKinsey developed it in the 1970s and it does give you that organizational snapshot. Performance on one axis, potential on the other, everyone placed in their box. For succession planning at the leadership level, it serves a purpose.
But for actual employee development? For internal mobility? For transparency?
That's where the Success Circle works differently.
It's built to be shared with employees. Connected to your competency framework, showing them exactly where they stand across your strategic pillars whether that's performance, culture, development or whatever drives your organization forward. You can flip it to capability mode and suddenly you're seeing skill gaps across the whole organization, not just individual placements.
An employee can look at their own Success Circle and actually use it to guide their development. They can see what capabilities they need to build, where they sit now, where they could move.
The secrecy disappears and development becomes something employees can actively navigate instead of something done to them in hidden meetings.
So why would you use both?
Because they solve different problems. The Nine-Box Grid still works for high-level succession conversations and organizational planning where you need that bird's eye view. When leadership needs to see the full talent landscape quickly, it delivers.
But when you want employees to own their development, when you're serious about internal mobility, when you believe transparency builds trust... the Success Circle gives you something the grid never could.
The organizations getting this right aren't being dogmatic. They're using both tools strategically, knowing when to apply which one and why.
What are you using for succession planning and development right now? Comment if you're exploring how to balance assessment with transparency - I'm curious how other HR leaders are thinking about this.
