Data-driven vs. data-informed decision-making

The Netflix Data War is a very interesting post about the internal discussions that happen between Netflix’s content team and their data team. In short, data isn’t everything:

[…] in almost any decision-making situation involving data, there is some non-zero percentage of the process that involves “gut”. The reason is because not all information about a process can be incorporated into a data analysis, and it’s important for data analysts to realize that.

That’s an important point to reflect on. It doesn’t matter how complete a data model is. There are some variables that simply cannot be included, because it’s impossible to know what should be included in any particular model.

Apart from that, it’s also just a fascinating look at the internal workings of Netflix.
