Optimize for completion of features, not busyness of humans. Start with ditching scrum. Have everyone focus on exactly one user story at a time until it is complete and passes QA. Once it does, go on to the next one. Every time I suggest this, people tell me I'm crazy, but every time I've talked a team into trying this it has increased their throughput. There are lots of reasons why this works. It reduces time lost to queuing, reduces crosstalk and coherence penalties, tamps down on Parkinsons Law, and many more.
