I have to completely agree with that paragraph. As long as we are talking about metrics, impact is the one to measure.
Ok, if you already are measuring impact and has a correct prioritization of it above anything else, adding delivery date and time spent won't hurt. But if you don't prioritize it above anything else, you are simply begging for a huge failure.
