The Amazon model of "Single Threaded Ownership" doesn't mean focusing on only a single responsibility. Instead it means that each responsibility has only a single owner.

"i.e., instead of multi-tasking, you are focusing on a single thread of work or focus at a time"

Amazon is a hierarchical organization. From the inside, that results in crystal clarity on who is responsible for everything, which is one of the greatest benefits.
