I love to see IDEO and Frog at the beginning of the list. I think this tells a lot about your background/influences. I personally came from an Industrial Design background, and those two company simply spread their process/methodology across many design field. To me, that means that the UCD approach is still solid, even if there are “faster” methodology like “Design Sprints”. Each approach has their pros and cons, I think it would be nice to see two team working on the same “problem”, applying the two methodology, and have a look to the final results. It would be a nice “challenge”.
