Carl and Fred discussing a question from an Inside FMEA reader on the subject of Process FMEA. It brings up a general topic of root cause, and whether assigning the cause to various forms of operator error is useful.
Join Carl and Fred as they discuss how to determine the Cause in Process FMEA.
- Deming teaches us to focus on the process, not the person.
- Deming’s red bead experiment.
- Westinghouse experiment on efficacy of measurements
- Erroring proof the design and the process can improve the manufacturing or assembly process
- Robust design can help reduce process sensitivity
- Some Process FMEAs use “Operator Error” as most common Cause; better is to determine and describe the deficiency in the process itself.
- Operator training and work instructions are both important
- Make designs as easy to assemble as possible; Design for Manufacturing/Assembly
- What about human element, if manufacturing process no longer needs human involvement?
- Improve the process, don’t blame the operator
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.
