One of the barriers Kate mentioned was the financial expectations put on board members, particularly in cultural organizations because it is a source of their funding.
One way we've mitigated that is by having young people join our board, and we have artists on our board. We realized that when choosing between someone who is a corporate executive and someone who is an artist or a young person by simply giving them a bye on that. We valued that they were giving in other ways, and so that barrier went away for us and allowed us to have generational diversity that we wouldn't normally have seen. It also makes it possible for artists to be very engaged, as they should be, in what we're doing at the museum.
I would say that managing that financial expectation would remove an important barrier so that you can bring in the people who can give you the content and the participation you need.
