A great read from the Decomposition blog about the day in the life of a Data Scientist. I consider myself a Data Scientist by any other name. The blog article by Sean does a great job of breaking down the essence of making better decisions for the organization you may be involved.
I've always thought asking good questions is the start of good analysis. The organizations basically doesn't know what it doesn't know. A good Data Scientist will be a like a sleuth looking for clues. In all honesty that may be the most fun about being a Data Scientist.
