The big thing about Data, not little d data, is that we all envision it as the answer to our prayers and some box that we can open that will make the tough job of thinking something we need to do less of.
In fact, Data is more than just metrics…it opens up a bigger box of decisions, ones that require us not just to examine data, but to look at data from the point of view of how does it influence my decision making process and how does it effect me when I am not making wise decisions that the data doesn’t back up…(or, how do you keep yourself honest because we know that we can all spin our data anyway that we hope.)
