Release It! Design and Deploy Production-Ready Software

Why this matters here

Nygard's Release It! shows how integration assumptions—retries, partial states, missing fields, edge-case classifications—diverge from production behavior under change, and why production-ready systems need stability patterns at those boundaries. Coupling extends that diagnosis to schedule pressure: a thin adapter that absorbs vendor assumptions into the domain core can let an external dependency quietly rewrite the system's own logic.
