At OOPLSA 98, Booch convened the first society of software architects (or some such).
Having read all his writing (ditto Yourdon, Brooks, Rumblaugh, etc), I was super excited.
During the Q&A I finally got to ask “What is software architecture?”
Booch replied “Software architecture is what software architects do.”
Bubble popped.
I gave up seeking the council of the priesthood and blazed my own path.
Every time I see a shop with designated Software Architects who hog the architecture work, it's a fucking mess. Because then Software Architects don't get rewarded in their careers for making software. They get rewarded for writing white papers and coming up with "brilliant" architectures and impressing executives who know less than them about technology. Which is mostly inversely correlated with actually making it easier for developers to get real work done.
Jacobson was a little more method focused. You can see how his introduction of use cases started the idea of talking to your customer about what they need.
I remember seeing Rose and thinking this will make a huge improvement only to be repeatedly confused and frustrated that it seemed to make everything take longer.
