Performance Vs. Potential: Who Should You Promote?

In brief

Performance tells you how well someone does the job they have. Potential is supposed to tell you how well they’ll do the next one.
Most companies measure performance carefully and judge potential by gut feeling.
The fix isn’t choosing one over the other. It’s defining potential in behaviors you can actually see.

Every promotion decision comes down to the same question. Do you promote the person who’s delivering the most right now, or the person you think will be best in the bigger role?

Most companies say they look at both. In practice, one of them gets measured and the other gets guessed. Here’s how the two compare.

A: Performance

What it is: how well someone does their current job. The results they deliver, and ideally how they deliver them.

How companies measure it: goals, targets, review ratings, the numbers.

What it tells you: whether this person is good at the job they have today.

Why companies lean on it: it’s visible, it’s measurable and it feels fair. The person who delivered the most seems like the obvious choice. That’s the thinking behind “they earned it”.

What it misses: the next job often asks for different behaviors. A top salesperson isn’t automatically a strong sales manager. Some of the most important behaviors at the next level, like developing people or setting direction, may never have been asked of them before. That’s how a company ends up promoting its best performer and losing a strong individual contributor.

B: Potential

What it is: someone’s ability to grow into a bigger role.

How companies measure it: usually, they don’t. Potential is often a manager’s sense that someone “has it.” Leadership presence, ambition, being seen as sharp.

What it tells you: in theory, who will succeed at the next level.

Why companies like it: it lets them look past the numbers and bet on someone who could grow.

What it misses: when potential isn’t defined, it turns into a feeling. And feelings tend to favor people who look, talk and work like the people already in charge. The quiet person who makes the whole team better can get passed over for the confident one who speaks up in every meeting.

Side by side

What it looks at: performance looks back. Potential looks forward.
How it’s measured: performance is usually measured with data. Potential is usually judged by opinion.
The risk: performance alone promotes people into jobs they weren’t prepared for. Potential alone promotes people based on impressions.
What it says about your culture: every promotion shows employees what actually gets rewarded. People watch who moves up far more closely than they read the values.

The verdict

You need both, but potential has to mean something specific.

The most useful definition of potential is this: the person is already showing some of the next level’s behaviors in the job they have now. A future manager is already helping teammates get better. A future senior leader is already thinking beyond their own team. That’s something you can see and describe, not just sense.

So promote people who perform well in their current role and are already showing the behaviors the next role needs. If no one is showing those behaviors yet, that’s not a talent problem. It’s a development problem. Here’s how to develop employees for the job they’ll have next.

How to make the call

Describe the next role in behaviors. Not the job description. What does someone need to do well at that level? (Start with how to turn your values into behaviors.)
Look for evidence, not impressions. Ask for specific examples of the candidate showing those behaviors now.
Check how they got their results. Strong numbers achieved by working around people are a warning sign for a leadership role.
Ask the people around them. Peers and direct reports often see behaviors that leaders don’t.
Name the gap. If they’re not ready yet, say what’s missing and how they’ll build it.

A spreadsheet or a tool can organize the data, but it can’t tell you what your culture needs from its next leaders. I wrote about that in AI succession planning.
