I'd like to see them round up as many engineers as possible and rota them on a healthy 24/7 schedule. There comes a point where you just can't be productive for 7 days a week. If 4 days is proven to be productive, then put them on a 4 day rota. Otherwise, the status quo of 5 days.

Some of the greatest ideas are conceived when away from work with just time to think on your own. We always need breaks and rest.
