AI Source of Truth

A source of truth is what your organization agrees is authoritative when facts conflict. For AI, that agreement must be explicit. Models do not resolve organizational ambiguity. They retrieve what ranks highest and state it with confidence.

Without a designated source of truth, customers get different refund answers from the chatbot, the help center search, and email macros. Employees get different guidance from the copilot and the internal wiki. The model is consistent in tone and wrong in fact.

Sources of truth are scoped. Refund amounts may come from policy. Setup steps may come from docs. Sales talk tracks may come from enablement. AI needs to know which collection wins for which question type.

Maintaining a source of truth is an executive commitment, not a technical trick. It means retiring duplicates, updating downstream systems, and refusing to let AI cite convenience copies.

Organizations accumulate convenience copies: mirrored wikis, exported PDFs, slide summaries. AI does not know which copy is authoritative unless you declare it. Convenience copies become accidental sources of truth.

Declaring sources of truth forces uncomfortable cleanup. That cleanup is the point.

Executives should treat source-of-truth maintenance as a quarterly business process, not a documentation cleanup when someone has time. AI makes stale copies visible at scale.

Identify authoritative collections per domain: pricing, refunds, security, SLAs. Mark them in metadata and retrieval policy so they rank above secondary sources when topics overlap.

Version authoritative documents explicitly. When the Nintendo Refund Policy changes, the old version leaves the approved set. Historical copies remain for audit but not for live retrieval.

Wire precedence into RAG and answer contracts. High-stakes queries check authoritative collections first. Secondary sources supplement context but do not override claims.

Test against the source of truth. Answer suites encode expected facts from authoritative docs. Any drift fails the release until resolved.

Maintain a precedence table by topic and audience. When Help Center prose simplifies policy language, precedence rules keep numeric limits tied to policy collections.

Audit quarterly for shadow copies indexed outside authoritative collections. Shadow copies are where stale answers hide.

Publish an internal registry of authoritative sources with owners and escalation contacts. New hires and vendors should onboard to the registry before touching AI configs.

Nintendo declares the Nintendo Refund Policy site the sole source of truth for refund eligibility and windows. Help articles may explain how to request a refund but may not invent new rules. The chatbot cites policy passages for limits and Help Center steps for navigation.

When a blog post from marketing mentions a hassle-free 30-day guarantee, governance flags the conflict. Marketing updates the post or the chatbot policy adds a prohibited claim. The source of truth wins.
