Si Chen has a nice write up of a talk he gave discussing OFBiz, and more general, open source in the business world:

When I started getting involved in the free software world, open source was very squarely aimed at tools, and applications for our fellow geeks. It’s interesting to watch it march off in new directions, such as Ubuntu on the desktop (my wife requested that I put Ubuntu on her new laptop!) and systems like OFBiz, which are very much aimed at higher level business processes.
