When to use it
Use it at the end of a tough feedback conversation. Agreeing on a follow-up date shows you care how things go next and gives you both a natural time to check in. It moves on from the hard part without pretending it didn't happen.
Example
You: “Let's check in next Friday to see how the new approach is going.”
Teammate: “Sounds good. I'll have the first week's numbers by then.”
In an email or Slack message
Send a short note afterward: “Thanks for the conversation today. I've put 15 minutes on Friday to check in on how the new approach is going.” Then keep that meeting.
