Data Consistency

What is Data Consistency?

Consistency is a property of the broader stack, not a single record. A contact might be perfectly accurate in isolation in two systems but inconsistent across them — different titles, different emails, different lifecycle stages. The cause is usually independent updates without a sync layer: marketing updates the title in their tool, sales updates it in the CRM, neither knows the other did it. The fix is a defined source of truth per field (marketing owns engagement fields, sales owns opportunity fields, ops owns firmographic fields) plus a sync layer that propagates the canonical value. Without explicit ownership, even excellent individual tools produce systematic inconsistency.

Why it matters

• Eliminates contradictions that erode rep and analyst trust in the data.
• Required for accurate reporting — the same metric in two tools must equal the same number.
• Powers cross-system automation — workflows that span tools need consistent inputs to work.

Use cases

• Source-of-truth mapping. Explicit ownership defined per field across the stack.
• Bi-directional sync. Changes propagate both ways between CRM and marketing automation.
• Consistency audit. Periodic check that the same record matches across systems.
