BI Tool

BI tools (the Looker/Tableau/Metabase class) surface warehouse data as dashboards and ad-hoc analysis, democratizing access with governance strings attached.

Deployment lessons

The semantic layer is the prize: metric definitions encoded once (what is an FTD, an active, NGR — this glossary as code) end the parallel-spreadsheet civil wars. Self-service works with curated models; raw-table access reproduces the chaos it promised to end. Certified dashboards for recurring decisions, exploration space for questions — and usage auditing, because unused dashboards mark either solved problems or ignored ones, and the difference matters.
