Robust Quality and Reliability
Join Kirk and Fred as they discuss how making a product with less variation, and closer to the target, will result in less warranty returns. We discuss Deming and Taguchi and the article “Robust Quality” which is accessible from a link below in the show notes
- The problem of variation and errors in manufacturing significantly contributes to latent defects and field failures
- Margins of capability and strength in a product must exceed the use specifications in order to allow for manufacturing variations
- Many products, especially consumer portable electronics, will be subjected to unreasonable over-stress conditions, so the more strength in the product the more delight from customers when it survives accidental abuse
- We cannot design a product to be indestructible and make it cost competitive, but should build it to the fundamental limit of the technology as the end-use conditions may change as products may be used in extreme conditions.
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.
