This article is talking about a role typically called “data analyst”. They help product managers, marketing, operations, etc by running reports, building dashboards, (business intelligence), building data models, running an exploratory analysis, analyzing A/B tests (product analytics) or things like building marketing attribution models or timeseries forecasting.

It’s the job that’s 80% of what a data scientist does but without Python or R. But mostly it depends because no one can decide what these roles should be called or what their responsibilities should be.
