Kirk and Fred discussing how much we should invest in backup power or systems redundancy to prepare for rare weather or use conditions.
Join Kirk and Fred as they discuss how much money do we need to spend to have backup systems or increasing the strength or robustness of systems to insure reliabile use or availability.
- Engineering always has tradeoffs between costs and reliability and we know that someone will accidentally or on purpose drop a cell phone out a 12-story building window. Should we considering making cell phones that can withstand that abuse?
- Fred lives in a beautiful wooded area in California, but the tradeoffs are that they lose power fairly often, either due to weather or the power company cutting off electrical service to prevent possible forest fires from power lines arcing. Spending money to buy and install a automatic backup generator to prepare for the occasional loss of power is much better than a catastrophic forest fire.
- The bottom line is that we cannot prepare for all rare weather or environmental conditions that cause failures, and we have to make priorities based on the impacts of a failure. Safety is of course the highest priority.
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.
