Yes : this is a very important point. In the compagny where I work (they
don't pay me enough to make me give their name :-), there were a report
written on this subject. A team cannot start from scratch such a work. It
means that you will need some "gurus" to help you not to make too much
MAJOR errors. And the team must be "young enough" to be able to switch to
object oriented stuff.

BTW, I am not sure that pure object oriented thinking is good for real
time software. If the implementation rely on high level objects, are you
sure that you'll be able to control the timings ?
