1. There are many different engineering courses and the methods of education differ greatly.
Is the school teaching the student or encouraging the student to learn themselves? (Traditional tech school / university approaches) "Learn the topic" or "read for the degree"?
2. Are the students being encouraged to be analytical? Highly encouraged in Europe but seemingly less so here in the US.
3. Having some qualification in engineering, does not make you an engineer. You don't enter the workforce as an engineer (as the article claims)
It might help if the authors of the article had engineering degrees (maybe they do but a 30 second look at the HBR pages for each author proved little.)
Engineers know that an engineering degree completely changes the way one sees the world. It is subsequently observed very differently from those who do not have an engineering degree.
