The only engineer in a business meeting..

[Aldryic C'boas]

I really don't understand situations like these. Why not just stand up for yourself and tell them how things are done and why instead of being buttraped into doing shit with unrealistic timeframes/resources. You got hired by them because you know the stuff that they don't, so go show them.

That's not how the real world works.  Informing senior management of their ignorance, no matter how gently worded, is typically a one-way ticket out the door.
