Three ways to get into senior management:
1/ Have a loud obnoxious/condescending laugh and must love to hear yourself talk even when you're not making sense. This is a must-have in ES.
2/ Able to effectively interrupt productive meetings and add very little input causing people to wonder what you just said exactly thus delaying product a few months, but just as long as your voice was heard (see example 1).
OR
3/ Be quiet, be an excellent paper-pusher and just do what your seniors tell you to do and never stick up for the people you actually manage.
Please note: You do not need any design experience for these roles.
Designers complain about management, and then when they get promoted to manager (because there's not many options for actual "design" promotions) they just roll over on their bellies forgetting everything they complained about - just to keep that nice management paycheck coming. Seen in time and time again. Until someone steps up to the plate and challenges them nothing will ever change here.
