Cause (because of)

Stringing crew calibration variance

Uncertain Event (there is a risk that)

As-built sag exceeds design tolerance

Consequence (which would lead to)

Rework of tensioning and re-inspection

Root Cause

Stringing crew calibration variance

Trigger / Threshold

QA survey flags out-of-tolerance spans

Early Warning Indicator

QA survey flags out-of-tolerance spans

Assumptions
