I'm not sure that the Top 10 Myths offered by Blue Avocado are the 100% top ten myths but these are certainly a good starting point.
I'm particularly fond of the myth about board size (16) and the expectaiton that boards are supposed to raise money.
Regarding size, I've always maintained that as an Exec, 3 was a great number for board size but no way near helpful in terms of bringing community and other input. I've also maintained that size really doesn't matter as much as having the "right" people at the table (committed, passionate) with clear roles and responsibilities and good support and structure to be able to do what has been agreed upon.
Regarding fundraising, yes, it's great when board members are committed to and have the capacity (e.g. access) to be helpful. And yes, many institutional donors are more welcoming of board members as the requesters of support. And yes, maybe there is a consequence if the board plays no role in helping request support (like not enough money). But is raising money are requirement of board members? Not implicitly. Members must reach an agreement about this and then hold themselves accountable for implementation.
Anyway, check-out the myths. This is a good thought piece that can generate some healthy conversation around your board table. A cautionary note: the refutes to the myths are not necessarily any more factual than the myths themselves.
