Lessons Learned from Deploying Conversational BI Agents

After the business and finance teams piloted Databricks Genie (now Genie Agent), the author found that it is indeed functional within narrow, clear data domains. When limited to a single star schema with clear field names, around 15 tables, and instructed with example questions containing verified SQL, queries like "last month's returns by region" can return results directly, reducing support tickets.
However, performance degrades rapidly when connected to broad, messy schemas: with ambiguous field names, unclear join paths, or multiple definitions for the same metric, it will answer confidently but incorrectly. The author argues that such tools actually expose data modeling debt; the issue isn't whether "users know how to ask questions," but whether the semantic layer and data model have been properly organized first.
