I didnt get my Masters in a specifically technical field. Engineering Management was 60% Industrial Engineering and 40% business.

I found 2 classes useful-

>Lean Principles- changed my life, I started using Industrial Engineering at home and sharing my findings with the internet. It has been very popular.

>Marketing class- 2 lessons, if you are going to put years into a project, do a marketing plan. Also, learned how incredibly important marketing is.

Everything else was basically useless. Had a few crazies as professors in my business classes. Engineering classes were not bad, but not helpful.

So 2/10 classes were useful? But incredibly useful.
