Maybe. Great care must be taken if any kind of template of failure mode library is used to complete an RCM analysis.[Read more…]

How much should you pay attention to readability scores generated from tools like the Flesch-Kincaid Readability Formula? As a technical professional, you probably should pay careful attention. But remember, while improving the Flesch-Kincaid score is important for accessibility and readability, balancing this with accurately conveying the technical information is essential.
Readability is a quality of your business writing. People will be able to understand your sentences easily if your text’s readability is high. If the readability is low, people still might understand what you’re saying, but reading your text is likely a draining experience, but people may still understand it.
Big words and complex sentences aren’t bad. Using too many of them demands much more concentration from your reader. Big words and complex sentences are also harder if someone’s first language is not yours or the reader has some form of visual or hearing impairment.[Read more…]
Barringer Process Reliability – Your factory performance on a single page!
Barringer Process Reliability (BPR) was developed by Paul H. Barringer, a fellow reliability engineer “extraordinaire” and an outstanding mentor for myself and countless others in this field of practice. BPR highlights operational issues. Not addressed and mitigated, those could have significant revenue impacts. A BPR analysis uses the Weibull probability plot which happens to be a very well-known tool in the field of Reliability Engineering. On one side of a sheet of paper only, the BPR plot can tell the true “story” on the operation.[Read more…]

“Too many cooks spoil the broth” goes the Elizabethan poet George Gascoigne’s proverb. Although only written down in circa 1575 it had probably been around for many years beforehand. It is still used today and, far from being archaic, it’s become more and more relevant despite mankind’s predilection towards efficiency and effectiveness. But why?[Read more…]

What do you know about Reliability Centered Maintenance?
Despite its well-documented successes, Reliability Centered Maintenance (RCM) has always drawn a lot of discussion and controversy. Much of it is because of a lack of understanding and “myths” generated to discredit RCM as a viable business solution. Here we attempt to fill in some of those gaps in understanding and debunk some of the myths.[Read more…]
To help select which work orders to do first in situations of resource shortage many CMMS provide calculations for maintenance work order priority. Deciding maintenance work priority is a risk decision. The presence of risk totally changes the way to allocate maintenance job priority if you want to compare situations equally1. When you work with risk you cannot use a linear priority scale. Using linear priority ranking gives the wrong order of importance for doing maintenance work.[Read more…]
EPA announced that the promulgation of National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters is postponed to January 16, 2011. The regulation, commonly referred to as Boiler MACT, will affect approx. 13,500 boilers at various facilities deemed to be major sources of hazardous air pollutants (HAPs).[Read more…]

The current state of the quality profession is affected by shifting business infrastructures and changing definitions of brand quality.
Businesses need to react and change against external pressures like increased frequency of consumer communications, the availability of big data, expanding regulations and standards, and the expectations to innovate quickly. The quality profession is at risk of losing its effectiveness in the overall business operations if it does not proactively change with the business.[Read more…]
A tutorial explaining the Physics of Failure method applied to regularly failing roller bearings in a dewatering press. After three years of exhaustive efforts to solve the cause of the bearing failures it was decided to test Physics of Failure Analysis with the aim of finding a lasting answer.
The Backbone of High-Quality Operations
In the world of industrial and manufacturing enterprises, where precision and reliability are paramount, maintenance leadership stands as the unsung hero. Behind the scenes, these individuals and teams are the custodians of high-quality operations, ensuring that machinery hums with efficiency, downtime is minimized, and standards are not just met but exceeded. Let’s take a closer look at the essence of exemplary maintenance leadership and why it’s the cornerstone of a well-oiled operation.[Read more…]

The New-Products manager asked me, “Your actuarial failure rate estimates (from vehicle registrations, bills-of-materials, and automotive aftermarket store sales) are for dead-forever parts with at most one failure. What if auto parts could be renewed or replaced more than once?” Chagrined, I wrote a spreadsheet program to estimate actuarial rates for renewal processes, without life data. But what is the corresponding estimator from grouped, cohort renewal counts like the Kaplan-Meier estimator for grouped, cohort failure counts?[Read more…]

Failure of Ship Hulls Due to Rot
British oak forests provided the wood to build the fleets that fought the Seven Years’ War, American Revolutionary War, French Revolution, and the Napoleonic Wars. New trees had to mature for 80-120 years for shipbuilding. By the early 1800s, three-quarters of British oak forests had been harvested to fight a half century of naval wars. Additionally, a scourge of dry rot reduced the service life of Britain’s main battle ships from the historical 25 years to less than 7 years. Britain had a severe national security problem – the Timber Crisis.[Read more…]
