Before joining Microsoft, I always thought that working with data is something that only data scientists and analysts do - a PM sets out the path for the product, the data science team provides the numbers and insights, and then engineering drives the implementation. What I’ve noticed, however, is that data scientists are much more scarce than I expected, and I had too many features to ship that I needed data analysis on than I had data team members available to do the analysis. Being more well-versed in data does not mean that you don’t need a data science team - they still are a major factor in your product’s success, as they operate at a much higher scale.
