Your Reliability Engineering Professional Development Site
A Crisis in the Home IT departmentIf you are the head of your home IT department, you may relate to this tale
Last night my wonderful wife Stacy was riddled with angst over the disruption of her binge watching a spy series, a mild crisis with our own IT hardware.
The cause of her disappointment was the failure of our new large screen Ultra High Definition (UHD) Smart TV to deliver a drama series with a reasonable picture and sound quality. [Read more…]

Kirk and Fred discussing the challenge of getting samples to test during product development. Early prototypes of new products are typically scarce, expensive, and in high demand to many engineering teams to test. HALT testing requires pushing the product to operational limits and discovering what will fail which is scary for management and engineers that do not understand the value of information that is discovered with empirical limit tests.

Kirk and Fred discussing the difficulty in getting to root cause of a component failures. In many cases a component failure is not due to a intrinsic failure mechanism in the component, but instead is due to a circuit application issue such as rapid voltage spikes or transients. They also discuss the issues with Li-ion battery failures in Samsung and Boeing leading to costly recalls and failures.
