It's as simple as this. When people don't unload their opinions and feel like they've been listened to, they won't really get on board. - Patrick Lencioni

Ironically, for peer-to-peer accountability to become a part of a team's culture, it has to be modeled by the leader. That's right. Even though I said earlier that the best kind of accountability is peer-to-peer, the key to making it stick is the willingness of the team leader to do something I call "enter the danger" whenever someone needs to be called on their behavior or performance. That means being willing to step right into the middle of a difficult issue and remind individual team members of their responsibility, both in terms of behavior and results. But most leaders I know have a far easier time holding people accountable for their results than they do for behavioral issues. This is a problem because behavioral problems almost always precede results. That means team members have to be willing to call each other on behavioral issues, as uncomfortable as that might be, and if they see their leader balk at doing this, then they aren't going to do it themselves.

The kind of trust that is necessary to build a great team is what I call vulnerability-based trust. This is what happens when members get to a point where they are completely comfortable being transparent, honest, and naked with one another, where they say and genuinely mean things like "I screwed up," "I need help," "Your idea is better than mine," "I wish I could learn to do that as well as you do," and even, "I'm sorry." When everyone on a team knows that everyone else is vulnerable enough to say and mean those things, and that no one is going to hide his or her weaknesses or mistakes, they develop a deep and uncommon sense of trust. They speak more freely and fearlessly with one another and don't waste time and energy putting on airs or pretending to be someone they're not. Over time, this creates a bond that exceeds what many people ever experience in their lives and,

truly nimble organizations dare to create clarity at all times, even when they are not completely certain about whether it is correct. And if they later see a need to change course, they do so without hesitation or apology, and thus create clarity around the new idea or answer.
