Two things stuck out to me. A lot of the roles/responsibilities stuff is very similar to Holocracy. Like a lot of methodologies, Holocracy may be better taken loosely. And flexible, but clear roles is one of the nicer things from that world. And the bit about having teams work on only one project at a time has a lot of backing in the book Principles of Development Flow. A lot of things done in the name of efficiency actually slow things down. And packing in your spare cycles with extra projects is definitely one of them.
