Root Cause Analysis
Updated 2026-08-13
INTRODUCTION
English translation pending.
CORE DEFINITION
Root cause analysis means tracing a problem to its fundamental cause rather than its surface symptoms, using tools such as the 5 Whys, the fishbone diagram, and fault tree analysis. The scaffold is cure the cause, not the symptom: without it the same problem returns, because the conditions that produce it were never removed.
SCAFFOLDING EFFECT
Reduce cognitive load
- Keep asking why: climb the causal chain past the first convenient answer. - Separate proximate from root: mark which cause is a symptom and which is the source. - Fix at the source: intervene where recurrence is actually prevented.
Anchor fast decisions
Symptoms are downstream outputs, so treating them leaves the generating mechanism intact and the symptom regenerates. Each why moves one step upstream, and at the source a single intervention can break the chain for every downstream symptom, which is why depth multiplies the value of the fix.
