Master system reliability while controlling cost through a practical breakdown of lifecycle cost analysis and engineering risk management. This episode explains core reliability metrics including failure rate (λ), Mean Time Between Failures (MTBF), and system availability, and shows how engineers use the Bathtub Curve to separate infant mortality from wear-out failures for smarter maintenance planning.

We dive into Quantified Risk Assessment (QRA), examining how failure probability and consequence intersect to drive real engineering decisions. Learn how to optimize total cost of ownership across capital investment, preventive maintenance, repairs, downtime, and operational risk.

This analysis covers redundancy, over-design, common mode failures, Reliability Centered Maintenance (RCM), Safety Integrity Levels (SIL), and ALARP risk principles, giving engineers the tools to design high-integrity systems without wasting money or overcomplicating infrastructure.
