Management information systems?

Did anyone actually use the book that they reference?  Do we need it?

Hard to say without knowing your level of expertise.  If you're not familiar with Davar, their courses don't do a lot of hand-holding.  There aren't videos and 120 quizzes along the way like SDC.

My suggestion would be that if you have any concern about the sufficiency of the course materials, go ahead and grab the book off that big auction website for $13.  Not much of an investment to be on the safe side.
