Yes, it's kind of interesting that way.  Three of the main
practitioners of OO methodologies and modeling strategies all ended up
working for Rational,  leaving them with the odd situation of having
the proponents of three different modelling schemes on staff.  Clearly
that's a problem they needed to solve, and along the way, the solution
has become a standard, not that that's a bad thing for the rest of us
either, but it seems to be something that benefits Rational most of
all...  on the other hand, it may be that Rational Rose really is
"that damn good" (personally, I have zero experience with it).
