Book Review: An Elementary Guide to Reliability

Book Review: An Elementary Guide to Reliability

If you sort your Amazon search on ‘reliability engineering’ by price: low to high, you may find some interesting titles available for free or maybe a few pennies. Not one to resist a chance to fill another bookcase, it’s been a bit of a spending spree.

One of the reasons I am interested in older titles is to determine why MTBF is so prevalent today. So far, still looking and learning along the way.

There are many great books in our field. Sure, some are older. Some are not at all useful or helpful.

This book review is the first in what may become a monthly addition to the NoMTBF blog.

Today’s review is on the book, An Elementary Guide to Reliability (3rd) Third Edition, by G. W. A. Dummer and R. C. Winton. [Read more…]

5 Why’s

5 Why’s

The 5 Whys technique is a powerful tool for root cause analysis, originally developed by Sakichi Toyoda and later popularized by Taiichi Ohno within the Toyota Production System. This method involves asking “why” five times to drill down to the root cause of a problem, rather than just addressing its symptoms. In the context of product development, particularly in the automotive industry, the 5 Whys approach can significantly improve overall reliability by uncovering the true sources of failure modes.

Equipment Defect Elimination Strategy

Equipment Defect Elimination Strategy

If you want to drastically reduce maintenance costs, stop lost production, eradicate unplanned outages and equipment breakdowns, you need to stop the continual introduction of defects and errors into your operation.

You do that by using quality management practices to drive continuous improvement of your management systems and so continuously improve the business processes, and your peoples’ knowledge.

Abstract:

To reduce maintenance costs and production downtime it is necessary to reduce the causes of the maintenance and downtime.  Both maintenance and downtime are an effect and not a cause.  The causes can be traced back to defects and errors from a variety of sources.  Knowing that defects eventually lead to future equipment failures, production downtime and lost profits, it is necessary put strategies into place to purposely prevent them occurring in the first place and to eliminate them if they are present.

PM Communications: Orders, Ordered, or Orderly Execution

PM Communications: Orders, Ordered, or Orderly Execution

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

Orders and being ordered can mean many things to many people.  In biology order concerns the taxonomic rank for classifying organisms.  More generally speaking it concerns the arrangement of people or things in relation to each other in some form of pattern, sequence, or method.  Alternatively, it can mean an authoritative command or instructions that are, typically, conveyed in a particular sequence.  When ordering a meal, for example, it’s normally done in the order in which the food will be served, but that’s always best clarified in some countries!

However, and despite orders regulating many of the things we do and being an intimate part of our lives, the concept of giving or taking ‘orders’ is taken as reprehensible and repugnant behaviour by some.  Ordering for them, outside of restaurants or other purveyors of supplies, smacks of being in the army or being subjugated.  Regimentation and discipline are often frowned upon by some of our more sensitive colleagues.

Measurement Systems Analysis using SigmaXL software

Measurement Systems Analysis using SigmaXL software

Dear friends, many of the viewers had requested for an introductory video on measurement systems analysis (MSA) and Gauge Repeatability and Reproducibility (R&R) Study. We are happy to release this video on MSA! In this video, Hemant Urdhwareshe, Fellow of American Society for Quality, and ASQ Certified Six Sigma Master Black Belt, explains the terminology of measurement systems and also illustrates how to conduct, analyse and interpret the results of a Gauge R&R Study. Hemant has illustrated this with an application example using template from SigmaXL software. Your feedback on the video is welcome!

When Do Failures Count?

When Do Failures Count?

One technique to calculate a product’s MTBF is to count the number of failures and divide by the tally of operating time.

You already know, kind reader, that using MTBF has its own perils, yet it is done. We do not have to look very far to see someone estimating or calculating MTBF, as if it were a useful representation of reliability… alas, I digress.

Counting failures would appear to be an easy task. It apparently is not. [Read more…]

Correlation vs. Causation

Correlation vs. Causation

In the field of reliability engineering, distinguishing between correlation and causation is essential for accurately identifying the root causes of system failures and ensuring the reliability of engineered systems.

Correlation refers to a statistical relationship between two variables where changes in one variable are associated with changes in another. However, this relationship does not imply that one variable causes the other to change. For example, an increase in ice cream sales and shark attacks are correlated because both increase during the summer, but one does not cause the other.

Making Sense of Gage R&R Analysis

Making Sense of Gage R&R Analysis

(Originally published in Quality Magazine, October 2025)

The term Measurement Systems Analysis (MSA) refers to a collection of experimental and statistical methods designed to evaluate the error introduced by a measurement system, and the resulting usefulness of that system for a particular application. In manufacturing, measurement system quality directly affects decisions about processes, products, and a manufacturer’s ability to meet their customer’s requirements.

Never, Never, Never Use FRACAS Like This 

Never, Never, Never Use FRACAS Like This 

 The article was written to cause people to question traditional approaches to FRACAS. In time senior managers in companies will come to realise that FRACAS has little chance of successfully improving their company. They then can instead look for what does work to move their operations to world class production performance.

“Uptime”, will there be a fourth edition?

“Uptime”, will there be a fourth edition?

Uptime is now in its 3rd edition

My book, “Uptime – Strategies for Excellence in Maintenance Management”, now in its 3rd edition includes a chapter on “Evidence Based Asset Management”. It emphasizes the use of historical data, enhanced (substantially in most cases) by “evidence” from experts obtained through a structured interview process of “knowledge elicitation.”

The questions asked are not leading, they are designed to get at reliability related information from the experiences of those who generally do not understand the mathematics of reliability. That process is painstakingly accurate and tedious. Projects that I was involved in, involved highly educated reliability and data science experts, and took upwards of 6 months to produce analytical results that could be used.

Rise and Fall of Bullsh*t Jobs

Rise and Fall of Bullsh*t Jobs

Don’t limit yourself. Many people limit themselves to what they think they can do. You can go as far as your mind lets you. What you believe, remember, you can achieve. ~Mary Kay Ash – Entrepreneur

Almost 40% of people according to surveys say their work and jobs make little difference to the organization, customer or marketplace. OK! So why do these jobs exist in VUCA time? Great question.
