Understanding the TapRooT® Root Cause Tree® Dictionary The TapRooT® Root Cause Tree® Dictionary is a foundational component of the TapRooT® System, a systematic process for incident investigation and problem-solving. Rather than relying on guesswork or brainstorming, this system uses an "expert system" approach to guide investigators through a structured hierarchy of potential causes to find fixable system weaknesses. The Core Components of the TapRooT® System
To understand the dictionary, it is essential to see how it fits into the broader investigation workflow:
SnapCharT®: A visual timeline used to document evidence and identify Causal Factors (mistakes or failures that directly led to the incident).
Root Cause Tree® Diagram: A decision tree that categorizes human performance and equipment reliability issues into logical paths. taproot root cause tree dictionary pdf
Root Cause Tree® Dictionary: A detailed guide containing yes/no questions for every node on the Root Cause Tree® to ensure consistent and evidence-based analysis. How the Root Cause Tree® Dictionary Works
The dictionary acts as the "instruction manual" for the Root Cause Tree®. It helps investigators move from a broad problem to a specific, actionable root cause by providing:
Standardized Definitions: It defines what each category on the tree means (e.g., what constitutes a "procedure" or a "work environment" issue).
Diagnostic Questions: For each node, the dictionary provides a list of bulleted questions. If an investigator answers "Yes" to a question based on their evidence, they follow that path deeper into the tree.
Consistency: By using the same set of questions, different investigators can reach the same conclusions, allowing companies to trend data across multiple incidents. Why Investigators Use the Dictionary Avoid: Scribd, course-sharing sites, or any “free PDF
The primary benefit of the dictionary is that it takes investigators beyond their current knowledge. Many internal investigations fail because the team only identifies causes they already understand. The TapRooT® dictionary prompts users to consider factors like fatigue, human engineering, and management systems that they might otherwise overlook.
