Root Cause Analysis in Maintenance

What You Will Learn

This book covers Root Cause Failure Analysis (RCFA) — the methodology to structurally eliminate recurring failures by addressing the true cause:

When to Use RCFA

Not every failure warrants a root cause analysis. Learn to select which problems deserve priority based on impact, frequency, and solvability.

The RCFA Team

Composition, roles, and facilitation of effective analysis sessions — from technicians to engineers, everyone contributes expertise.

Data Collection

What happened exactly, when, and under what circumstances? Learning to separate objective facts from assumptions and interpretations.

Causal Tree Analysis

Building the tree of causes and effects — from visible symptoms vertically and horizontally through to the real root causes: physical, human, and latent.

5-Why: A Faster Approach

When 5-Why is appropriate and how to use it correctly — avoiding the common pitfall of stopping too early.

Implementing Solutions

From identified cause to implemented and verified improvement — closing the loop so the failure stays away.
