Purpose
The method helps clarify workflows, data, causes, and improvements concretely. It looks for patterns, causes, weaknesses, or bottlenecks and derives actions. The result is captured as a Cause Tree, Evidence Notes, and countermeasures.
Operations
Root Cause Tree Analysis
Clarifies workflows, data, causes, and improvements by framing the problem precisely, branching possible causes, and defining countermeasures.
Which causal paths lead from observed problem to controllable causes, and which actions address the most likely paths?
MediumWorkshop1-3 h
How it works
The team follows the steps: frame the problem precisely, branch possible causes, add evidence and uncertainties, prioritize likely paths, and define countermeasures. Each step is captured visibly. At the end, a Cause Tree, Evidence Notes, and countermeasures are available so decisions, tests, or actions can follow directly.

Deep dive
In detail
Root Cause Tree Analysis follows a clear working logic: frame the problem precisely, branch possible causes, add evidence and uncertainties, prioritize likely paths, and define countermeasures. This turns the method into a visible thinking process rather than only a conversation. Participants move step by step from raw material, observations, or options toward a shared structure. The result is a Cause Tree, Evidence Notes, and countermeasures that make decisions, learning, or further planning actionable.
Facilitation
Prepare a clear guiding question, the right information, and a visible workspace. Plan about 1-3 h with 2-8 people and use the format in a facilitated workshop. The facilitation needs noticeable structure and preparation; short timeboxes, visible intermediate results, and a parking lot for open questions help.
