This is interesting. I wonder how much of a depressing effect throwing away the backlog every time will have on contributions from people on the team who have good ideas but are not super vocal, e.g. "what's the point of saying my ideas when they'll just be thrown out next time we do planning?"
I think the hope is that management looks at the backlog and uses that to guide their OKR creation so that there is a meeting in the middle of the upper level OKRs and the backlog.
