In my experience BI has no business being done by technical people. You need business people who are just technical enough to use the system for what they need.

In my experience BI has no business being done by technical people. You need business people who are just technical enough to use the system for what they need. You need domain knowledge and deep product understanding to know what data to be looking for, not a stats and CS whiz. In 99% of cases, SQL backed by a fast distributed analytics database and Tableau+Excel is enough for that. Even as a software engineer doing basic analytics charts for the service I own I don't want to be writing JavaScript. Ideally I wouldn't be writing SQL either.
