As someone in a work environment that does NOT have these 5 boring things in place, I can certainly speak to how much that slows productivity. So I think there's some value there, but it doesn't go into much detail, nor give you a game plan for implementing those things in your workplace. (And in many cases, you aren't empowered to implement them, so you either attempt to manage up or you find a new job.)

Empty is not the same as succinct & straight to the points. I'd say strong title, succint content. Each of the points invites as much thought as you can give it.

Not totally empty, but would have been much better digging into each of the 5 things and why they aren't commonly implemented.

Author hand waves at "organizations not wanting to open a can of worms" when I wanted to examine each squirmy helminth.

Only because you've heard this advice already.

The point is that these practices imply other practices and propagate their own culture. It's simple and not new but still unreasonably effective.
