If you have an engineer the whole point of them being able to claim the title is they are educated and expert in their field. Without knowledge and expertise in a field you aren't going to get any engineering done.

Which is different to saying anyone trained to be an engineer will be able to get stuff done. But getting stuff done was always a recnognised requirement of an engineer; i.e. by definition they should be getting stuff done.
