Of the eight conditions that are the signature of the highest-performing teams, there is one in particular that stands out —in study after study, irrespective of industry and irrespective of nationality—as the single most powerful predictor of a team’s productivity. It is each team member’s sense that “I have the chance to use my strengths every day at work.” No matter what kind of work your team is doing and no matter which part of the world you’re working in, your team will always be most productive when more team members feel delight and joy in what they do every day.

Diversity isn’t an impediment to building a great team—rather, it’s the fundamental ingredient without which a great team cannot exist. If we were all the same, there would doubtless be things that all of us could not do, and that therefore the team could not do. We need to partner with people whose strengths—whose weirdness, whose spikiness—is different from ours if we are to achieve results that demand more abilities than any of us has alone. And this means, in turn, that the more different we are from one another, the more we need one another. The more different we are, the more we rely on understanding and appreciating the strengths of others, and on building a shared understanding of purpose, and an atmosphere of safety and trust, so that those strengths can be most usefully put to work. Well-roundedness is a misguided and futile objective when it comes to individual people; but when it comes to teams, it’s an absolute necessity. The more diverse the team members, the more weird, spiky, and idiosyncratic they are, the more well-rounded the team.

The takeaway here is worth repeating: Getting the team right is the necessary precursor to getting the ideas right. It is easy to say you want talented people, and you do, but the way those people interact with one another is the real key. Even the smartest people can form an ineffective team if they are mismatched. That means it is better to focus on how a team is performing, not on the talents of the individuals within it. A good team is made up of people who complement each other. There is an important principle here that may seem obvious, yet - in my experience - is not obvious at all. Getting the right people and the right chemistry is more important than getting the right idea.

As Pak’s painting reveals, this is a complete misunderstanding of the point of a team. We did not invent teams to remind individuals that they are not as important as the group. We created teams precisely because it was the best mechanism for maximizing the unique qualities of each individual. We sat around the fire, pondering how the heck we were going to solve our problems—building shelter, finding our way, taking down animals far bigger than each of us—and we peered through the smoke at our uniquely gifted brothers and our sisters.

Not surprisingly, when Google conducted a study to determine the factors behind high-performing teams, psychological safety came out at the top of the list. (More details about the study can be found in James Graham, “What Google Learned from Its Quest to Build the Perfect Team,” New York Times, February 25, 2016.)
