ClearCase was the main system at Altitude Software in Portugal, and at Nokia, eventually replaced by Subversion.

Yes, it was, is, quite complex and requires a dedicated team, however there are plenty of features that are still to be made available as easyly.

I loved my view configurations, there were some tricks we could do for mix and match what code to see, and the build caches to this day is still not as integrated as sharing object and library files was back then.
