Lloyd Root Cause Pattern Diagrams are a data mining technique that takes complaint and/or failure codes for products in combination with their date of manufacture and time to failure in order to quickly plot graphical data patterns that indicate their root cause area.
Lloyd Diagrams are not only capable of identifying the root cause of elusive NTF issues, but they are just as applicable for the analysis of many transactional issues.
The following is the Lloyd Diagram presentation made at the 2012 ASQ World Conference in Anaheim, CA.
