When to Use Root Cause Analysis

Abstract

Carl and Fred discussing the reliability tool called “Root Cause Analysis,” and how RCA can be used in reliability programs.

Key Points

Join Carl and Fred as they discuss Root Cause Analysis (RCA).

Topics include:

• Be inquisitive on why things fail
• Using risk as a dial to determine when to use RCA
• Assessing risk using severity and frequency
• Getting to root cause and underlying failure mechanism for high-risk issues
• DMAIC and RCA
• Beware of “quick fix” that doesn’t solve the problem
• Field data integration and RCA for “hardy perennials”
• System FMEA helps understand system risk and where to use RCA
• Don’t have resources to use RCA on everything

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.
