CORE DEFINITION

Trace to the root: not satisfied with surface causes, ask about the root cause. Multi-level questioning: repeatedly ask "why" until the root cause is found. Systematic improvement: improve for the root cause rather than symptoms. Scaffolding role: solve problems at the root, rather than repeatedly extinguishing fires. Surface solutions are only temporary; if the root cause is not removed, the problem will recur. Related variants: root cause analysis, root cause analysis method, root cause tree, root cause analysis matrix, root cause tree.

Solve problems at the root, rather than repeatedly extinguishing fires. Surface solutions are only temporary; if the root cause is not removed, the problem will recur. Related variants: root cause analysis, root cause analysis method, root cause tree, root cause analysis matrix, root cause tree.

RCA traces the underlying cause of a problem by continuously asking 'why', rather than staying at the surface symptoms. Treating the root begins with tracing the source.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Define the problem
use methods like the Five Whys to drill down layer by layer
distinguish symptoms from root causes
implement measures targeting the root cause and verify.
