What is Inherent Reliability?

There are three important things we can learn about Inherent Reliability…from a cotton field! Watch as I explain what Inherent Reliability is. And, I discuss two important points any responsible custodian needs to know to achieve the Reliability that’s required from an asset. [Read more…]

Single Sample Z-test Hypothesis Testing for Mean with Known Variance

Single Sample Z-test Hypothesis Testing for Mean with Known Variance

Single Sample Z-test Hypothesis Testing for Mean with Known Variance

In the situation where you have a sample and would like to know if the population represented by the sample has a mean different than some specification, then this is the test for you. Oh, you also know, which is actually rather rare in practice, the actual variance of the population you drew the sample. [Read more…]

Cool new Reliability Culture book launch site

Cool new Reliability Culture book launch site

We made a cool “Reliability Culture” book launch website. The best part is that they let me put a big countdown timer on it like they have in James Bond films. Ya know, when the villain leaves James Bond in an easily escapable situation and there is a totally unnecessary timer building suspense to his (probably unlikely) demise.

The big difference being that in the Bond film we all know the big delivery will be before the timer goes off. In this situation the timer will go off and the delivery still won’t have happened because of Covid delays. Anyway it’s still cool.

But to save the day you can pre-order right now on Amazon or at Wiley right now.

Reliability Questions and Decisions

Reliability Questions and Decisions

Reliability Questions and Decisions

Very few reliability decisions are made by reliability engineers. Yet, reliability engineers are asked many questions concerning reliability. How reliable will this design be for customers? How will the system likely fail? How many failures should we expect next month?

How you answer these and the many other questions received does impact the reliability of your product or system. The information provided those that ask reliability related questions, with useful and practical information, can make better decisions which improves reliability performance.

Equipment Risk

Equipment Risk

Equipment Risk

Equipment risk is a reality of every oil or gas well completion, but is this risk the exclusive responsibility of the equipment manufacturer (OEM)?  To answer this question, let’s examine the major aspects of equipment risk in more detail. [Read more…]

Understanding the Principles of Reliability

Understanding the Principles of Reliability

Understanding the Principles of Reliability

The Reliability Approach… “Something understood and practiced by engineers and highly specialized technicians,” is apt to be the first reaction of the line supervisor, “certainly not an area where I can be expected to become involved.” Although this reaction is understandable; nothing is farther from reality. Let’s explore why in this paper. Please read until the surprising end (I know it is lengthy) and you will find that these Reliability Principles apply to any industry, any where at any time!

It’s All About Jobs!

Guest Post by John Ayers (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

COVID 19 throws a curve ball in the path of life and job security. If you compare life as a walk through a forest, then COVID-19 is a high stone wall (curve ball) along the path of life. Do you stop and retreat or go over or around it and continue your journey? I think you get through the pandemic and continue along the path back to job security and low unemployment. [Read more…]

Maintenance and Finance – Partners

CFO – you need to know that maintenance can help you be very strategic in achieving greater outputs, at low cost, and for a minimal investment. Maintenance and Asset Management managers, you need to enlist Finance as your ally. Both Finance and Maintenance / AM are after the same results. Understanding this is key to becoming partners in sustaining our businesses. After all, we both have the same goals in mind.

AND and OR Gate Probability Calculations

AND and OR Gate Probability Calculations

AND and OR Gate Probability Calculations

In system modeling and fault tree analysis (FTA) we use a set of similar calculations based on Boolean logic, the AND and OR gate probability calculations. Within FTA, the AND and OR gates are just two of many possible ways to model a system. Within system modeling, often reliability block diagrams (RBD) we model parallel and series elements of a system.

In order to do these basic calculations, we need to consider a few assumptions then proceed to the math.

Turning RCA into ROI in Healthcare? – Part 3 – Unknown Benefit…Intellectual Capital

The Greatest Benefit of RCA is Generally an Unknown…Intellectual Capital

Because business is measured based on credits and debits, this is how we must express effectiveness of initiatives in reality. However, the physical costs are NOT the greatest benefit derived from RCA when done properly. [Read more…]

It Takes a Village

It Takes a Village

It Takes a Village

In May 2018, we sponsored a summit that brought electric power reliability leaders from all over the country to Houston to discuss the gap in reliability. I’ve had a few weeks now to reflect on the event, and I want to share those thoughts with you.

If SDMyers was the mother of the Electric Power Reliability Summit (EPRS), then I feel like I was the midwife. [Read more…]

What are the Best Reference Books for Quality Engineers?

In this age of infinite information at our fingertips, it seems that fewer people are finding reference books and investing in their own libraries. After all, googling whatever’s on your mind is free and easy. But books, especially reference books and textbooks, still have a necessary place in our information age. [Read more…]

Teach and ask, don’t observe and judge. Maintenance assessments…

In my book, Uptime, I talk about doing a review or assessment to determine your current state as compared with your vision of some desired future state. This suggests to many that a formal assessment is needed. However, you might also notice that I removed the Appendix containing sample assessment questions. Here’s why… [Read more…]
