You can't lump them in a single category..so perhaps it's my misunderstanding but I'm not sure what you are trying to convey here?

I would really appreciate it if you could expand on these points.
As for the commitment, I think the point isn't the control the outcome but more keep an eye on your progress, I see it more of a checks and balances.
