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.

SPECIALIZATION. Nucor’s team members are deeply skilled, but they’re also multiskilled. Shared targets, cross-training, and malleable roles help them tackle the sort of tough, boundary-spanning problems that yield big productivity gains. There are no “slots” at Nucor and, thus, no artificial limits on where and how team members can contribute.

The 2015 European Working Conditions Survey found that just 14 percent of nonmanagerial employees were eligible for bonuses based on individual or team performance. The figure from a parallel American survey was slightly higher, at 15 percent, but only a scant 4 percent of frontline employees were eligible for productivity-related rewards.

We learned early on from Bill that when it came to creating teams, you have to put your bias blinders on (and that we all have biases). To him it was simple. Winning depends on having the best team, and the best teams include more women. A pair of 2010 studies bear Bill out on this point. They examined collective intelligence in teams: why are some teams “smarter” than the sum of their individual IQs? The answer is threefold: on the most effective teams everyone contributes rather than one or two people dominating discussions, people on those teams are better at reading complex emotional states, and...the teams have more women. This can be partly explained by the fact that women tend to be better at reading emotional states than men. So Bill always pushed us to consider women for any senior positions; he believed “you can always find a woman for a job, it may just take a little longer.” He helped recruit them when he could, such as when he got Ruth Porat to come on board as Google’s CFO in 2015.

At the end of the day, the best way to respect and reward the A players on your team is to surround them with other A players. This is how you attract more A players. And it means you must invest as much energy into hiring as you expect the team to invest in their jobs. You cannot expect someone to keep giving all of themselves if you put someone alongside them who isn’t willing to do the same. You need to be as unreasonable in how you build your team as you are in how you build your product or experience.
