Episode 24 — Use data minimization to reduce exposure without breaking the business (Domain 2C-4 Data Minimization)

This episode explains data minimization as an engineering and product discipline that reduces exposure by limiting collection, limiting use, and limiting retention to what is necessary for defined purposes. You’ll learn how to translate minimization into design choices, such as collecting fewer fields, reducing event granularity, shortening retention, avoiding sensitive enrichment, and splitting identifiers from content. We’ll cover common conflicts, like analytics and personalization goals pushing for “collect everything,” and we’ll show how to negotiate alternatives such as sampling, on-device processing, aggregation, and differential access patterns that still support business outcomes. You’ll also practice troubleshooting when minimization is blocked by legacy schemas, weak governance, or vendor defaults, and you’ll learn how CDPSE questions reward answers that reduce data footprint early and enforce minimization continuously.
