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…]
I was shocked to find out about our drug and medical supplies reliance on China, a dangerous risk to the U.S. I believe most Americans were also shocked. I believe this revelation is a game changer and the American people will insist on change. [Read more…]
I’m all about realizing the Inherent Reliability of my teeth and I use Condition Based Maintenance (CBM) to do it! Join me for a trip to my dentist’s office where Josie, my dental hygienist, details the Potential Failure Conditions she’s looking for. [Read more…]
Understanding now what perspective the executives have of an RCA initiative, how should RCA efforts be designed to report their results to the “C” level? Many would like to say “to express the results in a manner that demonstrates an increase in patient safety”. In a perfect world that would be nice, but what single metric expresses an increase in patient safety? Is there a line item on the Income Statement (IS) or Balance Sheet (BS) labeled “patient safety”? Not likely. [Read more…]
When a product is said to be of “high quality”, it is usually perceived to be reliable. Conversely, if the product is said to be “reliable”, it is probably perceived it to be of high quality. Why is this?
A product is an assembly of many components, all of which must be manufactured to some quality standard. Quality in component manufacturing is achieved through rigor in the manufacturer’s Quality Assurance (QA) system. QA systems define the Quality Control (QC) processes which ensure that materials, components, and assemblies meet the quality standard. The rigor must be appropriate for the product’s application. In critical applications (e.g. for sub-surface safety valves), the rigor must be high. [Read more…]
In the past, organizations have pr
acticed agility more than anything else because it is easy to simply pivot and put out small fires as they arise.
But with the world facing a global pandemic, statewide lock downs here in the United States, and a once booming economy now seemingly frozen in time, organizations both large and small are caught in the blaze as those small fires are now an uncontrollable inferno of a great unknown. [Read more…]
Reliability Centered Maintenance is an analytical process used in decision making about how best to manage equipment and system failures, and their consequences. Much of its output comprises maintenance tasks with assigned task frequencies. Those tasks will ultimately be managed in your Computerized Maintenance Management System (CMMS) or Enterprise Asset Management Systems (EAM). You don’t need software to perform RCM analysis, but it is helpful. Given the link between RCM output tasks and the proactive maintenance program you will manage using your CMMS / EAM, it seems to make sense to link or integrate the two software tools. Integration should enable automatic updates of the PM program stored in your CMMS/EAM whenever the RCM analysis is updated and possibly feed failure event historical data back to your RCM analysis with a notification that perhaps the analysis should be reviewed. Alas, that’s not going to happen. [Read more…]
Let’s celebrate the birthday of a very special Maintenance and Reliability event. In July 2018, the MSG-1 document turned 50 years old. Since many of the principles found in MSG-1 are embodied in RCM, that means RCM principles are also 50 years old! Take a trip down memory lane with me and MSG-1…the first of two documents that led us to Reliability Centered Maintenance! [Read more…]
An immediate purpose is to earn a living. You also may suggest the work is to improve the reliability of the product or system. Reduce downtime, reduce warranty, increase profit, etc.
That is fine for the overall purpose of reliability engineering work, yet in the day to day work, the specific task level, what is the purpose behind what we do?
In the previous Learning From Failure article, we reviewed that chloride stress corrosion cracking (Cl-SCC) of stainless steel readily occurs at temperatures above 140°F (>60°C) when exposed to aqueous (water-based) chlorides. Although the most attention is given to corrosion from product exposure, Cl-SCC can also occur from the external surfaces as a result of corrosion under insulation (CUI). Here is an example.

If 100 healthcare executives were polled about their definitions of “root cause analysis”, there would be 100 different answers. Here in is the problem, understanding the intent and power of Root Cause Analysis (RCA). For this reason, RCA is viewed as having either limited or phenomenal value to an organization. This article will seek to strip away the labels associated with RCA brands and focus on the processes, their results and how they are communicated (or miscommunicated) to executive management. Effective RCA efforts can fail because of their inability to demonstrate their value to the bottom-line of the organization. [Read more…]

I went to Washington recently to represent the SMRP Government Relations Smart Grid Committee, of which I am now the chair. I was there with other folks from SMRP to talk about the smart grid, and we ended up talking a lot about safety. The Society for Maintenance and Reliability Professionals—the fastest growing reliability organization in the world—is about to become an OSHA Alliance organization. That’s a big deal, because there are only a few organizations in the alliance and you have to jump through a lot of hoops to get in. SMRP has done that. [Read more…]
A commonly encountered fork in the career road for many successful engineers is to a) continue engineering or b) manage others who engineer. To continue engineering is an obvious choice, and an often desired one. [Read more…]
In his book “Willful Ignorance: The Mismeasurement of Uncertainty”, Herbert I. Weisberg notes: “Medical research is often held up as the paragon of statistical research methodology. Evidence-based medicine, based on randomized clinical trials, can provide proof of the effectiveness and safety of various drugs and other therapies.” (1) He goes on to note that clinical practitioners, who’s judgement is informed by evidence-based data, are finding little in the research that is useful.

Many of you may be surprised to learn that Reliability Centered Maintenance (RCM) was actually developed with cost cutting in mind! Aircraft maintenance costs were huge. For example the Douglas DC-8-32 aircraft (a four engine narrow body jet liner built from 1958 to 1967 that carried 150 passengers) required upwards of 4,000,000 man hours of maintenance work for only 20,000 hours of flying time! That’s 200 maintenance hours per operational revenue earning hour. With growing demand for air travel in those years, wide bodied aircraft were being designed (B747, DC-10 and L-1011). But air travel was prohibitively expensive. That limits the size of the market and growth potential. A solution was needed. [Read more…]
