How do you rank a reliability engineering book? Amazon and Goole can rank books based on algorithms, numbers, customer reviews and so on. But some books do a magnificent job of explaining the wrong concept. These books can have a great 'ranking' but be useless for you. So how do YOU rank YOUR reliability engineering books?
You can't talk about reliability engineering without talkiing about psychology. Why? Because reliability engineering decisions you make today have consequences, weeks, months, and years from now. So we can prioritize instant gratification (not doing reliability stuff) over future costs and consequences if we want. And that is where psychology comes into play.
Better Risk Management Abstract Greg and Fred discuss risk management tools specifically the advantages and disadvantages of using color -coded risk matrices. Key Points Join Greg and Fred as they discuss how risk matrices can be used effectively and graphically to communicate the likelihood and severity of risks. Risk matrices are inherently not precise and […]

Sample Size Considerations Abstract Dianna and Fred discuss sample size considerations for reliability testing. Key Points Join Dianna and Fred as they discuss sample size considerations, tackling the frequently asked question: “How many samples do I need?”. Topics include: Understanding the trade-offs between desired reliability/confidence levels and the massive sample sizes often required. Balancing statistical […]
Fault trees are very useful ways to visualize the logical relationship between events ... like which combinations of components need to fail for a system to fail, or which potential root causes need to occur for an undesirable event to occur. We tend to teach fault trees to unsuspecting students to solve only one type of problem ... and this is wrong! Want to learn more?
Dismissing Failures Abstract Chris and Fred discuss a common problem of dismissing or ignoring failures, especially when they don’t fit your ‘profile.’ Key Points Join Chris and Fred as they discuss the problems and hazards that arise when a failure occurs and is ignored. This can be tricky, as it can sometimes be hard to […]
Join Enrico and Fred as they discuss the pros, cons, and pitfalls of designing and running a test that has no failures, or does.
