Definition: The controlled, connected record linking requirements, design decisions, configurations, verification results, manufacturing records, quality events and certification evidence across a product's lifecycle. In regulated engineering, it acts as the product's operating memory, capturing what was required, what changed, who approved it, and what evidence supports each decision.
So what? A weak or fragmented thread pushes teams back onto meetings, spreadsheets and manual reconciliation to reconstruct decisions and evidence, which undermines traceability. A strong thread gives AI tools governed context, so they can support traceable engineering decisions rather than just produce plausible-sounding output.
Example: In aerospace, defence, nuclear or advanced manufacturing programmes, a digital thread might link a requirement through its design rationale, test evidence and certification submission, so any later change can be traced back to everything it affects downstream.
