Root Cause Analysis

The term root cause analysis is commonly used in manufacturing to summarize the activities involved in determining the variables or factors that impact the final quality or yield of the respective processes. For example, if a particular pattern of defects emerges in manufacture of silicon chips, engineers will pursue various methods and strategies for root cause analysis to determine the ultimate causes of those patterns of quality problems.

STATISTICA Process Optimization contains several designated tools for root cause analysis that will not only determine the individual factors that cause particular observed outcomes, but will also check for possible interactions among factors and automatically identify the best types of models that best account for the observed relationships between the causes and effects of quality problems.
