I have been in the industry and worked in 2 Countries for a number of consultancies sometimes my business card read: “Industrial designer” and sometimes it said “Product Designer” my responsibilities remained the same.
My last in-house corporate business card read, “Senior Engineer”, but my responsibilities and skill set remained those of an Industrial Designer.
What I find more than a little annoying is that many industries, banking in particular, refer to their services as “products”; loan products, retirement products, etc. I realize that in marketing, a product is anything that can be offered to a market that might satisfy a want or need, but it is still seems somehow misguided. And adds to the confusion (?).
