Root Cause Failure Analysis is an analytical approach used to identify and solve problems. Analysis is presented in the Seven Basic Tools of Quality in addition to advanced methods used to increase organizations effectiveness, efficiency and reliability.
Specific areas presented:
Traditional methods of Process Improvement demonstrate high failure rates: Business Process Reengineering (BPR) 50% TO 85%, Total Quality Management (TQM) 75% and Six Sigma 90% Proactive methods used in Process Reliability Modeling (PRM) will identify organizational issues before they result in loss of revenue.
The Post-it Exercise: Root Causes to process ineffectiveness are identified by Post-it survey.
Pareto Chart: The most common chart used by management; the Pareto is an ordered histogram that displays defects in order of frequency.
Cause and Effect diagrams (Fishbone or Ishikawa Diagram): The Ishikawa Fishbone Diagram (IFD) is a tool used to identify and present possible root causes to a problem. IFD was created by Dr. Kaoru Ishikawa; his method was popularized in early 1960s and used in the Kawasaki shipyards.
Process Reliability Modeling: Process Reliability Modeling (PRM) is a very sensitive measurement instrument used to identify areas of transactional or manufacturing processes contributing to loss of revenue and customer dissatisfaction. PRM is suited for any industry or service including medical processes. PRM has its roots in reliability engineering. Through employee surveys qualitative information is converted into quantitative data to determine the likelihood of passing work through the entire organization error free. Processes with a low reliability score are flagged and root cause failure analysis methods engaged.
Failure Mode Effects Analysis (FMEA): A step by step approach for identifying and resolving process problems effecting organization effectiveness, efficiency, reliability and safety.
Value Stream Mapping: Method used to document, analyze and improve the flow of information or materials required to produce a product or service for a customer.
