Root Cause Analysis: A Framework For Tool Selection, Mark Doggett Dec 2004

Root Cause Analysis: A Framework For Tool Selection, Mark Doggett

Mark Doggett

This article provides a framework for analyzing the performance of three popular root cause analysis tools: the cause-and-effect diagram, the interrelationship diagram, and the current reality tree. The literature confirmed that these tools have the capacity to find root causes with varying degrees of accuracy and quality. The literature, however, lacks a means for selecting the appropriate root cause analysis tool based upon objective performance criteria. Some of the important performance characteristics of root cause analysis tools include the ability to find root causes, causal interdependencies, factor relationships, and cause categories. Root cause analysis tools must also promote focus, stimulate ...

Selected Collaborative Problem-Solving Methods For Industry, Mark Doggett

Mark Doggett

In problem solving, the root cause of the problem produces an undesirable effect. Any pursuit that does not seek the root cause leads only to the symptom of the problem and, by definition, solving a symptom will not solve a problem. Problem solvers identify root causes of problems to be able to predict future cause and effect relationships. The purposeful application of an analysis method can address complex problems using a structured approach rather than emotion or intuition.
