Doing the right thing, not just the thing right.

means The degree to which something actually produces the result you wanted, as opposed to just producing activity.

from From 'effective,' tracing back to Latin 'efficere' — 'to work out, accomplish' — built from 'ex-' (out) plus 'facere' (to do or make). So buried in the word is a quiet demand: not just doing, but doing until something is actually made to happen. The '-ness' tacked on later turns the quality into a measurable noun, the thing you point to when you ask 'but did it work?'
