SSOT — Single Source of Truth

A trusted information source that provides the authoritative and consistently maintained version of specific data.

Definition

Single Source of Truth (SSOT) is an information management principle in which a designated system, repository or dataset is recognized as the authoritative source for a particular class of information. SSOT minimizes inconsistencies, duplication and conflicting data by ensuring that all users and connected systems reference the same validated information.

Why It Matters

A Single Source of Truth provides the authoritative source of information for a defined dataset or business domain.

In Practice

Single Source of Truth is a foundational principle of digital engineering and enterprise information management, supporting data quality, governance, system integration and lifecycle information management.

Common Misuse

A Single Source of Truth identifies the authoritative source for specific information, whereas Master Data Management governs how master data is created, maintained and synchronized across multiple systems.
