The trick to doing this is not just to tell the person how well she’s performed, or how good she is. While simple praise is by no means a bad thing, it captures a moment in the past rather than creating the possibility of more such moments in the future. Instead, what you’ll want to do is tell the person what you experienced when that moment of excellence caught your attention—your instantaneous reaction to what worked. For a team member, nothing is more believable, and thus more powerful, than your sharing what you saw from her and how it made you feel. Or what it made you think. Or what it caused you to realize. Or how and where you will now rely on her. These are your reactions, and when you share them with specificity and with detail, you aren’t judging her or rating her or fixing her. You are simply reflecting to her the unique “dent” she just made in the world, as seen through one person’s eyes—yours. And precisely because it isn’t a judgment or a rating, but is instead a simple reaction, it is authoritative and beyond question.

My biggest takeaways were: Criticize the behavior, not the person. Praise in public; criticize in private. Praise with emotion, criticize without emotion.

Whether criticism or praise, it’s a leader’s job to give their team feedback all the time. But every person on the team should be hearing more about what they did well than what they could do better, or they’re going to feel deflated and unmotivated. And if you can’t find more compliments to deliver than criticism, that’s a failure in leadership—either you’re not coaching the person sufficiently, or you’ve tried and it’s not working, which means they should no longer be on the team.

These rules help your team to feel safe—especially if you practice them consistently. Consistency is one of the most important and underrated aspects of being a leader. A person can’t feel safe at work if they’re apprehensive about what version of their manager they’re going to encounter on any given day. So if you’re the boss, you need to be steady, controlling your moods so you don’t end up taking out that morning’s squabble with your spouse on a server with a wrinkled shirt.

This is the ideal—but let’s be honest: every once in a while, you’re going to mess up. When you do, apologize. There’s an inherent intensity that comes with being passionate about what you do, and on occasion, it can get the better of you. I’ve certainly expressed exasperation and disappointment in ways that weren’t textbook illustrations of how to handle a correction in the workplace. But every time, I’ve made sure to apologize—not for the feedback itself, but for the way I delivered it.

I’m always interested in what others, and not just the esteemed critic from The New York Times, think about what we’re doing. If your business involves making people happy, then you can’t be good at it if you don’t care what people think. The day you stop reading your criticism is the day you grow complacent, and irrelevance won’t be far behind.

You have to know the people you’re working with. Some people are totally pragmatic about criticism; correct them privately and without emotion, and they’ll receive the reproach in exactly the spirit in which it’s offered. Three minutes later, they’ll have apologized for the mistake, taken the note, and the two of you will have moved on to chatting about last night’s Mets game.

Other folks are sensitive to criticism. This isn’t necessarily a negative characteristic—it’s usually an indication they want to do a good job and feel deeply wounded at any suggestion that they haven’t. But those people are going to react, no matter what you say or how gently and diplomatically you say it, so you’d better spend some time planning exactly how you’re going to deliver the feedback. And you’d be wise to budget time to spend with them afterward, so you can sit with them and let them know that they’re still loved.

Then there are the people who can’t or won’t hear what you’re saying unless it comes with a little thunder. If your reprimand is too mild and conversational, they won’t believe you’re serious. With these people, you’re going to have to get into it a little bit, even if that’s not your usual managerial style.
