I work in aerospace engineering and i hesitate to hire PhD. In my experience, PhD always want to find the best engineering solution and cant, dont, or wont bother to understand the business implications of budget and schedule. They simply cant say, “good enough,” and move on. They always need 1 more study, or to so the 1 month model instead of the 1 day hand calc because it gives a more accurate answer, and theyre a pain in the ass to manage. Sometimes all management needs to understand is directional trends to make a decision
We recently ran into a situation where we got an update to NX and the new version physically couldnt model a part we had designed. The part was very specifically designed around its aero features. Our CFD PhD said itd take him 3 months to determine the impact to the features.
I sat down with one of the other engineers, we ran through every scenario possible, ran it all through 1d flow solver models, and determined worst case scenario (which we were certain wasnt going to happen) was 7 degree F change to the metal temperature. When we’re talking metal temps 1200F+, 7 is insignificant.
We came to that conclusion in 4 hours and told the team to keep going with what NX could do.
Within your area of expertise too, even. In my field, Ph.Ds are viewed as being overqualified with not enough field experience

Bingo. It’s like this here too.
