About this view

Investigation detail provides structured root-cause analysis with hypothesis tracking, evidence collection, and CAPA linkage. Fishbone categories are organized fields so teams can record causal factors consistently across methods, materials, equipment, and people. Effectiveness check commitments ensure corrective plans are verified after implementation. Next actions include completing evidence items and confirming linked CAPAs remain on track.

Root Cause Hypotheses

Root cause identified as Human error. Further analysis confirms this was the primary contributing factor.

Level 1: Machine • Level 2: Human error
