I agree with you Deb, that someone with an MBA could help some museums save money, but that can backfire too.  I worked at a museum in Kansas where a person with an entirely business background was brought as Director.  The board's ideas was to start looking for ways to finance the museum in the future when grant money might become tight.  It was a big mistake!  This Director, backed by the businessmen on the board, changed the entire museum.  Interpreters were fired, exhibit buildings were sealed with plexiglass so visitors could look in but not enter, and programming, especially "gunfights" and blacksmithing, were eliminated to cut insurance premiums.  The museum went from a facility that showed the history of early Kansas to static exhibits.  There was no one left to answer quesstions and no programming to add additional information.  When staff objected to the changes and asked to be heard, the curator was fired as an example to the others (of course that wasn't the excuse the board gave.

All this happened after I left and there is a different director at that museum now (one with no history or business background).  I have no figures on how the changes effected visitor attendence, just hearsay from friends who live in the town.  But money didn't go to the staff, it came from cutting the staff.

Someone with a business degree might be able to help, but the lesson to learn here is that everything needs to be balanced.
