Nicolas Nova thinks that Norman’s piece reflects “a narrow understanding of what field research about people can convey”. Nova also takes issue with the “distinction between improvement and breakthrough (or what [Norman] calls “revolutionary innovation”).” Perhaps, Nova says,” it’s a framing issue but the notion of a “breakthrough” seems a bit weird when one think about the whole history of technologies. This terms seems more appealing to the marketing/business people than observer of how objects evolved over time.’
