A good question to ask is: If this person were not already at the organization, would I recommend that another team hire him or her knowing what I know? Sarah, the employee who struggled with operating independently, was not somebody who I could see being successful anywhere within the company.

We encourage our managers to apply the Keeper Test regularly. But we are very careful to not have any firing quotas or ranking system. Rank-and-yank or “you must let go of X percent of your people” is just the type of rule-based process that we try to avoid. More important, these methods get managers to let go of mediocre employees, but they kill teamwork at the same time. I want our high-performing employees to compete against Netflix’s competitors, not one another. With rank-and-yank what you gain in talent density you lose in reduced collaboration.

Fortunately, there is no reason to choose between high talent density and strong collaboration. With the Keeper Test we can achieve both. That’s because there is one critical way we are not like a professional sports team. On the Netflix team there is no fixed number of slots. Our sport isn’t being played to a rule book and we don’t have limits on how many people we play with. One employee doesn’t have to lose for the other to win. On the contrary, the more excellence we have on the team, the more we accomplish. The more we accomplish, the more we grow. The more we grow, the more positions we add to our roster. The more positions we add, the more space there is for high-performing talent.

It’s clear that the Keeper Test increases talent density, but it also creates worry. Employees report feelings ranging from “mildly concerned” to “occasionally terrified” that they will be cut from the team.

There are two steps we take at Netflix to minimize fear around the office. The first step is that any employee who is feeling the type of anxiety that Marta and Derek discussed is encouraged to use what we call the “Keeper Test Prompt” as soon as possible. That almost always improves the situation. During your next one-to-one with your boss ask the following question: “If I were thinking of leaving, how hard would you work to change my mind?

The same principle applies to any meeting you attend. What issues do you expect to arise in the meeting? Who will take which position? Privately commit yourself in advance to some judgments about these issues, and you will have daily opportunities to learn, improve, and recalibrate your judgment.
