You have to hire people that don't have big egos, and are also high performers. Some people will obviously be higher performers than others but without egos communication works. If someone is not performing well, everyone should feel open and trusted enough to communicate about it and find a resolution.

If you hire even one person with a big ego communication breaks down and you are in for a really bad time. Pretty much every high performance team knows this and put a lot of effort at weeding these people out.

A lot of it is also setting a good example once you've made the hire through your team and company culture. Hopefully when someone joins the team they will see how others communicate and carry themselves and it will rub off on them. Everyone should have enough respect and trust in everyone else not to have a huge ego even if they might have had one at their previous job where people treated one another poorly.

> It is possible to be disagreeable in a constructive way, combined with a “disagree-and-commit” attitude where the team’s success is the priority.

Disagreement is absolutely key to making a team work. Disagreeing with humility, and trusting others to take disagreement without having their egos involved, is what is needed. Being overly agreeable happens when you don't trust the other person to take your disagreement without ego.
