Giving feedback in a way people can actually hear
If feedback only happens when something blows up, you'll have a team that only hears bad news from you.
Specific, soon, and small
Within 24 hours of the moment, about a specific thing, kept short. Generic feedback ('be more proactive') doesn't change behavior. Specific feedback ('next time, call the customer before you leave the parking lot') does.
Praise in public, correct in private
The order matters. Public correction makes people defensive. Private praise feels withheld. Flip the defaults.
Ask for feedback back
'What's one thing I could do differently?' once a month, from a few people you trust. The answers will sting at first. They'll also make you better.
Take your version of this question further
This is one operator-tested angle on the question. Your shop, your size, your trade, and your team change the answer. Ask your specific version inside Ask a Shop Owner to get a response grounded in how owners like you actually handled it.
