I can remember a presentation in 2007 from Jonathan Arnowitz with the title Innovation and Design in a World of Engineering. In his presentation Jonathan warns us about the quality of a design process within an engineering environment. He also points out the differences between developers and designers. When I saw this presentation I couldn’t agree more. I think this was because I noticed that a lot of professionals with a developers mindset were calling themselves designers. Or even worse, a devigner, which often meant that they were neither good at programming nor at designing.
