In practice
The usual setup is a data warehouse, a modeling layer and dashboards or reports. It is good at answering the same high-level questions repeatedly.
BI isn't product analytics, which measures behavior inside a product. It also isn't customer feedback, which tells you what people said.
Why it matters for product builders
BI is strong on what happened and weak on why. The reason often sits in a customer conversation that never reached the warehouse.
