That awesome quote is attributed to Peter Drucker; a man of many skills and one who's wisdom I have an enormous amount of respect for. Like all great ideas though, it's a little too abstract to be of practical use without some extra thought and effort.
Without the extra effort, these ideas will inevitably be abused by people in support of their own agendas. It's not their fault of course, we all do that. In this case, I see more and more that we are starting to miss the point in an attempt to measure everything.
