How Much Reliability Data Is Enough?

Some may argue that just enough reliability data is just the right amount. Too much may lead to confusion, too little doesn’t inform well. The reliability work we do helps others make decisions, and recent work in how humans make decisions may help us prepare and present our results effectively.

If preparing reliability data-based recommendations, consider using less information. Ed O’Brien and Nadav Klein have found decision-makers tend to use much less data or information to make a decision than they think they will need.

If using data and the derived information to make a decision consider the situation carefully to know when to use a structured decision-making approach or to simply go with your gut. Daniel Kahneman and Gary Klein provide some insights and basic guidelines for decision making. [Read more…]

5 Ways to Keep Your Audience’s Attention

I have found the best way to lose an audience is to focus on statistical derivation. While this is a fascinating subject for me, it just doesn’t seem to hold an audience’s attention.

Having something interesting and useful to say is key to maintaining an audience’s attention, yet at times how we present helps them become distracted.

So, given great content or proposal, how can you help your audience not quickly check their phone, yet again? [Read more…]

The Importance of a Reliability Engineering Community

Years ago I was a part of a reliability engineering community and I had not met more than two or three members. This was before the internet and was using a new-fangled system called an email list.

At the time, it filled the role of helping me understand the many facets of reliability engineering. It helped me answer questions and allowed me to help others as well.

My desire is to help create more such communities that can help you and your organization improve the discussion concerning reliability. Let’s explore exactly how to make this work. [Read more…]

The Changing Support for a Reliability Engineer

In most organizations being a reliability engineer is a lonely position. I like to think we’re so effective that one or just a small team is all any organization needs.

As with any engineering position, we have specialized training and skills. We view the world and problems just a little differently then others. Then we use statistics, which tends to future isolate us from our peers.

For over 50 years there have been professional societies focused on supporting the professional education of reliability engineers. For nearly as long there have been trade journals and newsletters. Longer for technical journals and other scientific and engineering organizations and journals. [Read more…]
