Microspeak: who's in charge here?
drive
To push; to captain the initiative on a particular issue or project. "Ed is driving the HTML issue for the product."
own
To take responsibility for an issue. Ownership is even more serious than drivership; you can drive an issue without owning it, but it's unlikely that you would own it without also driving it (just like automobiles, in fact). Syn - Champion (as a verb; to "champion the issue"). Variant - Owning the Vision: Ownership on a loftier, almost metaphysical level.
