For a leader, giving feedback—both when things are going well and when they aren’t—is one of the most fundamental aspects of the job. Mastering this skill means that you can knock down two of the biggest barriers preventing your reports from doing great work—unclear expectations and inadequate skills—so that they know exactly where to aim and how to hit the target.

Give Task-Specific Feedback as Frequently as You Can.

As the name “task-specific” implies, you provide this kind of feedback about something that someone did after the fact. For example, after your report presents an analysis, tell her what you thought she did well and what could go better in the future. Be as precise and as detailed as you can.

This is the easiest type of feedback to give because it’s focused on the what rather than the who, so it feels less personal. If you find yourself struggling to get into the habit of giving feedback, start with this category.

Share Behavioral Feedback Thoughtfully and Regularly

When you zoom out and look at many examples of task-specific feedback for a report, what themes emerge? Does he make decisions quickly or slowly? Is he a process wizard or an unconventional thinker? Does he gravitate toward pragmatic or idealistic solutions?

Asking this question about themes helps you reflect on your report’s unique strengths or areas of development as shown in his patterns of behavior.

Behavioral feedback is useful because it provides a level of personalization and depth that is missing from task-specific feedback. By connecting the dots across multiple examples, you can help people understand how their unique interests, personalities, and habits affect their ability to have impact.

When we first tested annual written 360s, we ran them like everyone else. Each employee selected a handful of people she wanted to receive feedback from, and those people filled out the report anonymously, rating the employee on a scale of 1 to 5 across a series of categories and leaving comments. We used a “Start, Stop, Continue” format for the comments to ensure that people didn’t just pat each other on the back but gave concrete, actionable feedback… We no longer have employees rate each other on a scale of 1 to 5, since we don’t link the process to raises, promotions, or firings. The goal is to help everyone get better, not to categorize them into boxes. The other big improvement is that each person can now give feedback to as many colleagues as they choose at any level in the organization—not just direct reports, line managers, or a few teammates who have invited input. Most people at Netflix provide feedback for at least ten colleagues, but thirty or forty is common. I received comments from seventy-one people on my 2018 report.

If you’d like to try the live 360 for yourself, here are a few tips:

Length and location: A live 360 will take several hours. Do it over dinner (or at least include a meal) and keep the group small. We sometimes have sessions with ten or twelve people, but eight or fewer is more manageable. For a group of eight you’ll need about three hours. A group of twelve could run to five hours.

Method: All feedback should be provided and received as an actionable gift following the 4A feedback guidelines outlined in chapter 2. The leader will need to explain this in advance and monitor it during the session. Positive actionable feedback (continue to . . .) is fine, but keep it in check. A good mix is 25 percent positive and 75 percent developmental (start doing . . . and stop doing . . .). Any nonactionable fluff (“I think you’re a great colleague” or “I love working with you”) should be discouraged and stamped out.

Getting started: The first few feedback interactions will set the tone for the evening. Choose a feedback receiver who will receive tough feedback with openness and appreciation. Choose a feedback provider who will give the tough feedback, while following the 4A guidelines. Often the boss chooses to be the first to receive.

Live 360s work because of our high talent density and “no brilliant jerks” policy. If your employees are immature, have bad attitudes, or lack the self-confidence to show public vulnerability, you might not be ready to run these events. And even if you’re in a state of perfect readiness, you’ll need a strong moderator who makes sure all feedback falls within the 4A framework and steps in if someone says anything out of line.
