When you think of the perfect data science team, are you imagining 10 copies of the same professor of computer science and statistics, hands delicately stained with whiteboard marker? Applied data science is a team sport that's highly interdisciplinary. If you're keen to make your data useful with a decision intelligence engineering approach, here's my take on the order in which to grow your team. We start counting at zero, of course, since you need to have the ability to get data before it makes sense to talk about data analysis. If you're dealing with small datasets, data engineering is essentially entering some numbers into a spreadsheet.
