The most important action that a leader must take to encourage the building of trust on a team is to demonstrate vulnerability first. - Patrick Lencioni

An organization has to institutionalize its culture without bureaucratizing it.

The key is to take five minutes at the end of staff meetings and ask the question, "What do we need to communicate to our people?" After a few minutes of discussion, it will become apparent which issues need clarification and which are appropriate to communicate. Not only does this brief discussion avoid confusion among the executives themselves, it gives employees a sense that the people who head their respective departments are working together and coming to agreement on important issues.

Harmony itself is good, I suppose, if it comes as a result of working through issues constantly and cycling through conflict. But if it comes only as a result of people holding back their opinions and honest concerns, then it's a bad thing.
