I am sorry sir , I kindof disagree with you. Every new invention is out of need. So PLM was need of the industry and hence it came into existence.
I agree with you on upper managements need to have solid business fundamentals. They should be the one to drive PLM implementation and monitor the productivity and returns.
Old processes done in the old way is always going to give old results and that is lower efficienct, no control over losses long lead time for desing , slower product introduction to Market etc etc
