Warranty and field-failure trend analytics for quality strategy
Live Core high effect
Core capability
The system continuously monitors equipment and process behavior, helping operators and managers see abnormal situations early and respond before they become failures, quality losses, or downtime.
How it works
The system continuously compares current sensor behavior with normal operating patterns. When it detects a meaningful deviation, it evaluates severity and alerts the team early enough to prevent larger failures, quality losses, or downtime.
Application here
Statistical analysis of warranty claims and field failures reveals which components fail most, which trends are worsening, and where teams should act.
Business impact
This helps teams identify systematic quality problems and prioritize supplier and design actions that reduce warranty cost.
Limitations
Warranty data is delayed and often inconsistent. The analytics show patterns, but they do not prove root cause by themselves.
In production
This is already used in many factories to watch equipment and process behavior around the clock, detect abnormal situations early, and help teams intervene before quality loss or downtime grows.
Research
The next step is systems that do not only flag abnormal behavior, but help explain likely causes, identify the most relevant signals, and suggest what to inspect first.
Examples
Automotive OEM uses JD Power IQS data + internal warranty DB for quarterly quality strategy review; SPC dashboards on SAP QM identify trends by model line and supplier — .
