“On behalf of Fluor B&W Ports, I would like to offer my personal thanks for teaching your DLE Root Cause and Event Investigation course at our Piketon,OH training facilities… We sent a wide cross section of our personnel to attend the training, including managers, operators, mechanics and safety representatives, and the feedback we received has been extremely positive. You did an outstanding job of helping our personnel understand the fundamentals of causal analysis that will help us create an excellent problem solving organization. Your material was top notch and your subject matter expertise and delivery of the course content were way above average. Again, I thank you for providing excellent training that has contributed to improving our problem solving culture at Fluor B&W Portsmouth.”

By more effectively identifying the causes of our issues and events we were able to target our Corrective Actions to mitigate recurrence and improve our overall performanceYour understanding and use of the BlueDragon root cause method is best-in-class and on behalf of UDS and myself, I extend my sincerest
