Then do you believe that the tasks outlined above are in fact Engineering. If so, why do you think so? And what is your definition of what would constitute Engineering versus non-Engineering efforts?

It's true, my definition is US-based (maybe even based on a single state), and even more narrowly, it's based on US PE licensing requirements, which isn't even necessary for many Engineering fields these days. But at least I'm not dodging the question, here.

As an example, drafting is billed at a different rate than Engineering precisely because drawing in CAD itself is generally not considered Engineering.
