I think such posts (and books) are usually meant like checklists for people who already knows that stuff (not learning it), but want it formalized. Then when you have issues for example with team members, you can look at those resources and try to assess why something is going into the wrong direction. It's easier to enumerate those points then.
It seems this kind of posts/books is more aimed to selling oneself as a consulting business process expert in a corporate market than to teach anything to the practitioners. It's a bunch of soundbites aimed at a dilettante.
