Public Reporting of Failures
Join Kirk and Fred as they discuss product failure reporting to the public.
- Backblaze, a data storage company, publishes the annualized failure rates between thousands of hard drives from a variety of manufacturers and yet the drive manufacturers do not provide the public the most important data which is the root cause of those failures.
- Consumer Reports has a spring and fall surveys from the membership on consumer satisfaction including the reliability of products they purchased recently and that is one source of comparative reliability data available.
- The Warranty Week website does report warranty costs for public companies and that can provide motivation for companies with similar products to compete on reliability and reduce warranty failure rates.
- Legal liabilities prevent the public disclosure of the cause a vast majority of product failures and that limits the broader knowledge of reliability engineering, but this conflict is not going to end anytime soon.
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.
