概要

Organizations treat derived data—ad‑hoc dashboards, denormalized tables, ML features—as ‘free’ insight until a surprise bill, outage, or compliance question forces firefighting. This episode opens with a concrete vignette: a VP of Sales wakes to a $30,000 monthly cloud bill from the “Regional Sales Rollup” report and demands answers; Rina Patel, a Senior Data Engineer, explains how missing ownership and no rollback plan turned a 2‑hour analysis into months of toil. Mirko and guest analytics lead Carlos Mendoza present a one‑page Derived Data Contract (read verbatim on-air and available in show notes) and argue the counterintuitive claim: treat derived datasets as reversible products, not artifacts. Listeners get a live-filled example, three low‑friction week‑long rituals, a 7‑day freshness-and-cost audit, and a measurable pilot goal (catalog five derived datasets and cut surprise‑cost incidents by 50% in 30 days). CTA: copy the template from the notes, run the 7‑day audit, pilot one contract, and leave a review.
