1. A storage device production failure analysis system comprising:
- a factory quality control unit configured to transmit a trigger signal when a storage device production failure is detected; and
an analytics unit configured to determine a root cause of the storage device production failure by at least;
receiving the trigger signal from a factory quality control unit;
extracting storage device production data from a database when the trigger signal is received, wherein the storage device production data comprises process input variables;
identifying one or more potential root causes of the storage device production failure based in part on an analysis of the process input variables; and
generating a report indicating the process input variables that correspond to the root cause of the storage device production failure, the report comprising at least one of a decision tree graph, a leaf report and a correlation data chart.

Abstract
A production failure analysis system including a factory quality control unit configured to transmit a trigger signal when a production failure is detected, and an analytics unit. The analytics unit is configured to determine a root cause of the production failure by at least receiving the trigger signal from a factory quality control unit, extracting production data from a database when the trigger signal is received, wherein the production data includes process input variables, and identifying one or more potential root causes of the production failure based in part on an analysis of the process input variables.
