What does it mean if everyone around the table agrees with the decision? Does that mean that the decision is obvious, or does it mean that we don’t have enough diversity on the board?
Maybe everyone agrees because they are actually all the same people, they drink the same Kool-Aid and they always agree. Or does it mean that there are people on the board who are afraid to voice a dissenting opinion.
The chair of the board should be concerned if most of the decisions made by the board are made unanimously. This could indicate that there is not enough diversity on the board to provide a thorough discussion of all of the ramifications of a decision, or that people are not comfortable voicing their opinions.
