Customer Segmentation Without Personas
As someone who has made hundreds of personas throughout my career in my past life as an Experience Designer, I've come to loathe them.
They often sit idle within a Powerpoint and never make it into the game, sitting on the sidelines being a regret from various business managers, who really didn't give a shit about the process to begin with.
Now since being within Data Science I can automatically carve out segmented buckets daily from a predictive model and set a new course for a particular top performing buyer profile.
This is a method called K Means Clustering, you really don't care the name of this. But you should care about the large % increase in sales with immediate effect.
