This is the sort of historical revisionism and weak reporting that seriously pisses me off. Sutherland did not invent Scrum in the 80s, Scrum is not the founder of agile, there were 17 people involved, etc etc. That HBR is passing this along is seriously bad history/reporting
Just seen again a beautiful “agile enterprise transformation” led by a large consulting company: You get a reallocation of people to the offices. Cross-functionality is the new saviour.
