@chris Oops! Sorry for lumping you in with the old-timers. 😅
I didn’t realize this was still an issue in 2012.
The first time I saw a well-defined IC track, it was at an agency I joined in 2007. The titles went: Assoc. Software Eng. → Software Eng. → Sr. Software Eng. → Software Architect → Sr. Software Arch. → Dir. of Software Eng. (IC) → VP of Software Eng. (IC).
It blew my mind.
Nowadays, those upper levels are Staff, Principal, and Distinguished, rather than Architect, Director, and VP.
