Kirk and Fred discuss new product market release schedule pressures, and then after customers start finding reliability issues, the actual firefighting begins. Many times, those who quickly can fix the causes of failures, the firefighters, get many more accolades than those who find and mitigate product weaknesses that become failures during the design and development phase.

Historically, Reliability Engineering of Electronics has been dominated by the belief that 1) The life or percentage of complex hardware failures that occur over time can be estimated, predicted, or modeled, and 2) the Reliability of electronic systems can be calculated or estimated through statistical and probabilistic methods to improve hardware reliability. The amazing thing about this is that during the many decades that reliability
