And what more than two decades of research into teams and their leaders has to tell us is this: what distinguishes the best team leaders from the rest is their ability to meet these two categories of needs for the people on their teams. What we, as team members, want from you, our team leader, is firstly that you make us feel part of something bigger, that you show us how what we are doing together is important and meaningful; and secondly, that you make us feel that you can see us, and connect to us, and care about us, and challenge us, in a way that recognizes who we are as individuals. We ask you to give us this sense of universality—all of us together—and at the same time to recognize our own uniqueness; to magnify what we all share, and to lift up what is special about each of us. When you come to excel as a leader of a team it will be because you’ve successfully integrated these two quite distinct human needs.

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.

Two questions in the survey showed the strongest relationship to a worker’s feeling of trust in his team leader:

• Do I know clearly what is expected of me at work?

• Do I have the chance to use my strengths every day?

This data suggests that these two conditions—knowing what is expected, and being able to play to one’s strengths—are the foundations of trust. When a team leader, despite the ambiguities and the fluid and fast pace of the world of work, can help team members feel clarity about expectations and a sense that their best is recognized and utilized frequently, then trust is built, and a Fully Engaged team becomes more likely.

One way to think of these results is to imagine a team leader having three distinct jobs. Her first is to ensure her team members feel connected to the purpose and future of the company, even though she may not directly define those. Her second is to ensure that her team members, as a group, understand and support one another. And her third is to ensure that her team members, individually, understand what’s expected of them and how they can do their best work now and in the future, all while feeling recognized for who they are.

The subtlety here is that, as we saw above, the feeling of enthusiasm about a company’s mission, and confidence in its future, still vary team to team. In other words, our experience of our company is significantly mediated by our experience of our team.
