While I have been looking at how to do, and teach innovation for several years, it was only this month I discovered there were formal standards. After giving a pitch at CBRIN's First Wednesday Connect, I was chatting to Rizwan Khan, who pointed out that ISO TC 279 is developing innovation management standards. The idea of a standard for innovation sounds a contradiction in terms, but DE CASANOVE, and MOREL (2018), provide a useful overview of the work of the committee.
