I agree an ad - although I followed the sort of same advice which came from a stepdad 30 years ago: undergrad in bus admin and then masters in computer science. Seemed to do ok with this approach. Thought about a PhD, but was just burned out on more degree work (unless I could have someone else to cover the costs).
In most STEM fields I think it works better the other way around: an undergraduate degree in the STEM discipline and then an MBA. Or (if feasible) both an M.S. in the STEM field and an MBA.
