Failure Analysis and Field Failures: a Real Shortcut to Reliability Improvement

TL;DR

This paper discusses how thorough failure analysis of historical cases can reveal earlier failure events, leading to improved reliability and better prediction tools.

Contribution

It introduces a method of using failure analysis of past cases to enhance reliability assessment and prediction accuracy.

Findings

Failure analysis can uncover root causes linked to earlier events.

Reliability prediction tools can be refined through case-based insights.

Improved reliability models lead to better failure prevention strategies.

Abstract

Starting from two case histories, where only after thorough Failure Analysis the suddenly appearance of a failure was linked to much earlier events, the possibility of improving the reliability and of adjusting the reliability prediction tools are discussed.
