How to say “you need improvement” professionally
Why it can fall flat
“you need improvement”
After a string of disappointing results, managers often reach for “you need improvement,” but it's vague and reads like a verdict on the person, so they get defensive. The writer wants specific work to change and the person to see what better looks like.
Say this instead
- 01
The last two reports had errors in the figures. I need them checked before they reach me. Can we go through your checking process today?
Someone you manage · Chat
Use it for a repeated, specific problem, since it names what happened and what you need next.
- 02
I want to talk about the recent client summaries. They're missing key details, and I'd like us to agree on what a good summary looks like going forward.
Someone you manage · Email
A formal follow-up suits this one because it puts the standard in writing and opens a conversation.
- 03
Quick thought on the draft: the middle section is hard to follow. Could we tighten it before it goes out? Happy to go through it with you.

Peer feedback on shared work fits here, since it centers on the document and offers to fix it together.
- 04
Can I share some feedback on the weekly briefings? They often arrive late and miss the numbers my team needs. Could we agree a deadline and a format?
Boss · Email
You can raise a quality problem upward this way by tying it to the impact on your team and proposing a fix.
- 05
The files we received don't yet meet the brief we agreed. Could you send a revised version by Friday? I've listed the three points to fix below.
Client · Email
When a client's input or approved brief isn't being met, this is firm, specific and gives a date.
- 06
Your last two deadlines slipped. Let's talk tomorrow at 10 about what's getting in the way and how to hit the next one.
Someone you manage · SMS
A time-sensitive nudge that can't wait for a meeting is where this helps, and it sets up a proper conversation.
- 07
The shared tracker keeps going out of date, and it's holding up my work. Can we agree who updates it and when?
Coworker · SMS
For a quick, low-drama push, this one helps when a teammate's gaps are blocking you.
Examples
Hi Nicole, I'd like to talk about the last three project updates. They've arrived after the deadline and have been missing the budget figures I need. Could we meet on Thursday to agree what you need from me and how to get the next one in on time? Thanks, Paul
Hi Peyton, the last two invoices went out with the wrong dates. Can we go through the checking steps together this afternoon so it doesn't happen again?
What to avoid
- Labels like “sloppy” or “not good enough” with no example attached.
- Delivering the feedback in front of other people.
- Comparing the person with a colleague.
- Praise piled on so thickly that the real point gets lost.
- Raising the issue but never saying what a better result looks like.
