A manager notices something during the week: an order that left with an item missing, a quote that went out late, a customer conversation that could have gone better. They remember it. They plan to mention it at a more suitable moment.
The suitable moment turns out to be the review meeting, three months later. By then everything has merged into one general sentence: “You need to be more careful.” The person hears it and does not know what it refers to.
Often the manager was not the only one at fault. There was a valuable comment, but it was said after the situation had faded from memory.
Say it within a day
A comment is worth more while the situation is still in front of you. The person remembers what happened, what they thought and what they might have done differently. After a month that remains only as a vague impression.
Within a day does not mean in front of others or in the middle of a busy shift. It means the same day or the next, in two or three minutes, somewhere the person can speak. If you have no time, write one line down and say it as soon as you can.
Feedback is useful while the person can still connect it with what happened.
This applies to good things as well. Work that was done well and is not mentioned in time usually is not mentioned at all.
Describe what you saw, not what you think of the person
“You were careless” is a judgement about the person, and there is nothing to act on. “Yesterday the order left without the third bag; the list was complete, but we did not compare it with what we had in hand” describes what happened. Someone can act on that.
A useful comment has three short parts. What you saw, as concretely as possible. What effect it had, on the customer, the team or the work that follows. What could change next time. Then ask: how did you see the situation?
“Be more careful” is not a standard. “Check the list against what is in your hands before you close the order” is.
Listen to the answer. Often the person has a reason you had not seen: a system that was closing, an instruction that said otherwise, another job that called them away. What they say may show that the problem is not the person but the way the work is set up.
Agree on the next step
A comment that ends with “okay” and nothing else rarely changes anything. Before you part, say what will be done differently and when you will look at it again.
It can be simple: “Tomorrow before dispatch, compare the list with the order. On Monday, tell me how it went.” One small, checkable step is worth more than a general promise.
When the same comment is needed for different people, ask yourself whether the instruction was clear. A single mistake calls for a conversation. A mistake that repeats across the team calls for a change in the process. The Shift Lead planet has a routine for closing the shift with the open issues and the owner of each.
At the end of the week, go back to what you said. If something has changed, say so. A person who sees that their effort had an effect meets the next comment with less defence.
