The Problem
CRM data flows from many sources — apps, warehouses, manual entry, integrations. Changes upstream break downstream consumers. Firefighting dominates data team time without contracts.
What Data Contracts Specify
Schema (fields, types, constraints). Quality (completeness, accuracy thresholds). SLA (freshness, availability). Versioning. Breaking-change notification process. Enforcement mechanism.
Implementation
Declare contracts in code (YAML or similar). CI enforces on data producers. Consumers subscribe to specific versions. Breaking changes trigger notification + migration window, not silent failure.
Cultural Shift
Data engineers stop firefighting. Producers accept responsibility. Consumers stop hoarding workarounds. Contracts normalize the conversation. Tools help (Monte Carlo, Soda); culture matters more.
