This question is outside of my area of focus, but I agree based on what I've seen that most substantial gifts or endowments are the product of long-term relationships. In some cases, those relationships become so important that if the development director leaves the museum, sometimes the donors follow them out the door. It is also worth considering the possible effect on other staff members whose pay has no bonus structure or any other means of advancement. The compensation of registrars, exhibit preparators, visitor services and security personnel doesn't change if a big contribution comes in or if ticket sales go through the roof due to the exhibit that just opened. Internal equity can be a big deal, especially in an institution with relatively small staff. Just my $0.02 worth...
