Even after all this years I think this article is still current. After reading all your reviews I think that there was a misunderstanding of what my intention was. I wanted to show the difference between the two professions. There is not a single person that can claim to perform both tasks. I agree that it has to be a very strong collaboration among the people involved. But this does not mean to step in each other’s areas; again I will take doctors as an example. Exactly their method of collaboration has to apply in our field too!!!
