Our organization recently went through a re-org, and the Senior VP now oversees marketing, PR, fundraising, donor relations and development, event planning, etc. She is not an expert in all areas, and I'd say there are some areas where she has very little experience. It is her job to make sure the departments are functioning as a unit, to cast the tone and vision, etc. She is a really incredible leader and communicator, knows the right questions to ask, etc, to keep everything on track. I'm guess many executive level jobs are like this. If you are a leader and a visionary and have good management skills, I would consider it!
