CASE 07 · CASE ATLAS · LEVEL B WORKSHOP SCENARIO

Offshore power cable process

SITUATION

An offshore power-cable manufacturing process spans multiple suppliers and process steps, each generating its own quality records in different systems, making it hard to see whether a single cable segment's full evidence trail is complete before shipment.

EVIDENCE

Process records, material certificates and test reports from each supplier and process step, linked by cable segment and lot identifier where such linkage exists.

AI APPROACH

The Quality Evidence Graph connects available records across the supplier and manufacturing chain by segment identifier and surfaces where the chain is broken or a record is missing, rather than inferring a missing record's content.

KEY CONTROLS

A broken or missing link is reported as a coverage gap, not silently treated as satisfactory; the tool states which segments it could not trace end to end.

VALIDATION MEASURES

Measure coverage — the proportion of segments with a complete traceable chain — against a manually verified sample, and confirm the tool does not report false completeness.

HUMAN DECISION

The quality engineer decides whether an incomplete chain blocks shipment or requires supplier follow-up before release.

DISCUSSION QUESTIONS

  1. What does 'no finding' mean here if a third of the chain could not be traced at all?
  2. How do inconsistent supplier data formats affect what this tool can and cannot connect?
  3. Who is accountable when a gap in the graph is discovered after shipment?
