Section 75 of 103
74. Digital Thread
Stable section ID: S05-CON-015-SECTION-75 · 13 content blocks
A Digital Thread is the continuous, traceable set of relationships connecting engineering information, decisions, entities, configurations, and events across the lifecycle of an asset.
It may connect:
Definition → Design → Verification → Manufacturing → Logistics → Installation → Commissioning → Operation → Inspection → Maintenance → Upgrade → Disassembly → Reuse or Recovery
The Digital Thread shall preserve relationships among:
requirements and design decisions;
Product Types and manufactured instances;
Interfaces and compatibility declarations;
configurations and version transitions;
physical events and digital records;
evidence and conformance decisions;
failures, corrective actions, and reverification.
The Digital Thread is not necessarily a single database or linear file history. It may be distributed and graph-based, provided that identity, provenance, authority, chronology, and relationships remain recoverable.
A missing lifecycle record shall remain identifiable as a gap and shall not be replaced by an unsupported assumption.
