How to give a performance review that actually helps someone improve

Most performance reviews fail in one of two directions: too soft to be useful, or too harsh to land. Neither helps the person improve.

The two failure modes are mirror images of each other:

Too soft: Vague positives, vague concerns, nothing actionable. The person leaves feeling good but doesn't know what needs to change.

Too harsh: Accurate but delivered without context or acknowledgment. The person leaves defensive and checked out.

The goal isn't to find the middle ground. It's to be both honest and useful. That requires a different approach than most managers take.

Before the review: the prep that matters

The failure usually starts before the conversation begins.

A week before the conversation, ask yourself:

1. What are the two or three things this person does genuinely well? Not "works hard" or "is a team player." Specific, observable behaviors that have positive impact. If you can't name them, you haven't been paying attention.
2. What is most limiting their impact? Not a long list. The one or two things that, if addressed, would make the biggest difference.
3. What does good look like in the next 6 months? Not just "improve." What would you point to as evidence of growth?

If you can't answer these three questions clearly, do more preparation before the conversation.

The structure that works

Start with what's working. Be specific.

Not "you've done a great job this year" but "the way you handled the [project] rollout was exactly what I was hoping for. You got ahead of the stakeholder concerns early and the launch went cleanly. That's something I want you to keep doing."

Specific > general. Always.

Then address what needs to change. Also specifically.

"One area I want you to focus on this year is how you communicate upward. I've noticed that when you're behind on a project, I often find out through a status meeting rather than a heads-up from you. That puts me in a reactive position and affects my ability to support you. What I'm looking for is earlier escalation, even when the news is uncomfortable."

What makes this work: - It names the behavior, not the person ("how you communicate upward" not "you're not proactive enough") - It explains the impact ("puts me in a reactive position") - It's specific about what good looks like ("earlier escalation")

Then discuss development: their direction, not just your needs.

"Where do you want to be in two years? What's the work that energizes you? Let's make sure the development focus we set actually serves where you want to go, not just where I need you to grow."

People engage with development plans they helped shape.

Close with clarity on what happens next.

"So the two things I want us to focus on for the next six months are [X] and [Y]. I'd like to check in on these specifically in our 1:1s. Is there anything I can do to help make progress on these easier?"

What to do when the review is hard

If someone's performance is genuinely below expectations, the review needs to say that clearly.

The most common mistake here is softening the message so much that the person doesn't understand the seriousness of the situation. They leave thinking it went fine. Then they're blindsided when consequences follow.

If performance is a real concern:

• Name the gap explicitly: "Your output this quarter has been below what I expect at your level."
• Explain what you've observed, not what you've concluded: specific instances, not "you're not meeting expectations"
• Be clear about consequences: "If we don't see meaningful improvement in the next 90 days, we'll need to have a more serious conversation about fit."
• Offer support: "I want to see you succeed here. Here's what I'm willing to do to help."

This is not comfortable. It is kind, because it gives the person the information they need to actually do something about it.

The thing most managers skip

After the review, follow up in writing.

Not a formal document. A brief summary email: "Thanks for the conversation today. To summarize what we discussed: [two things going well], [one to two development areas], [specific next steps]. Let me know if you see this differently."

This does two things: it creates shared understanding of what was said, and it signals that you take the conversation seriously enough to document it.
