MTBF, who are you?

MTBF, who are you?

Meantime between failures MTF is a widely used reliability metric in various Industries, particularly in electronics and manufacturing. While it can be a valuable tool in certain scenarios, its misuse or misinterpretation can lead to costly mistakes. Let’s explore when MTBF is applicable and when it might be inappropriate to use.

By understanding when to use MTB and when to seek alternative methods, organizations can make more informed decisions about product design, maintenance strategies, and reliability improvements, ultimately leading to better products and more satisfied customers.

Show Me the Money in Maintenance! 

Show Me the Money in Maintenance! 

Find the fortune maintenance can make for your business. Unfortunately, maintenance people get praise when they repair breakdowns. This embeds and promotes a culture of equipment failure acceptance in a business. Maintenance must be used to prevent equipment failures, not fix them. If you want to start a culture of failure elimination in your business you have to start putting a money value on the breakdowns prevented by Maintenance. You have to start praising and recognising them for the breakdowns they didn’t let happen. Maintenance needs to be praised and glorified for the money it makes a company, not singled out for the money it spends.

Climate Change or Global Extinction?

Climate Change or Global Extinction?

Is climate change humanity’s greatest ever risk management failure?
The Guardian newspaper

Climate change. Global warming. These are the ‘new normal’ or the ultimate ‘Horsemen of the Apocalypse’. U.S. intelligence report said:

“Global environmental and ecological degradation, as well as climate change, are likely to fuel competition for resources, economic distress, and social discontent through 2019 and beyond. Climate hazards such as extreme weather, higher temperatures, droughts, floods, wildfires, storms, sea level rise, soil degradation, and acidifying oceans are intensifying, threatening infrastructure, health, and water and food security.”

Read more: Climate Change or Global Extinction?

Risk likelihoods as well as direct risk consequences are increasing. Extreme heat is impacting global food supply chains, housing near the ocean, increases in cancer, and other factors.

Are you a denier? According to a recent report, there’s a 95% likelihood that VUCANs are the drivers of climate change through carbon dioxide emission.

OK, is human extinction too strong of a prediction? The New York Times said:

“Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival .”

Story: You may be a green believer or even an evangelist. Or, you may be a denier. It really doesn’t matter.

We’re in a global heating environment and changing political environment. So, pay attention to sustainability. I was a green skeptic until I saw first-hand major environmental changes occurring over a few years. I catch & release salmon on the Columbia River in Oregon, USA., which is a beautiful and pristine environment. The problem is over the last 30 years, salmon fishing changed. Fewer fish. Smaller fish. Shorter fishing season. Not good. As an engineer, I thought maybe we were going through a macro weather cycle from cold to warm.

Work Lesson Earned: Climate is now directly tied to work and salaries. More people see climate change impacting job retention, promotional opportunities, and recruitment. A recent survey concluded 74% of executives say climate change poses risks to their job security.  How does climate change impact or may impact your work? Are there any opportunities for you? As traditional industries adapt to the changing environment, have you considered working in a green business? You’re saving humankind. You’re having fun. You’re doing good. You’re saving the planet.

Today’s Gremlin – Assumptions

Today’s Gremlin – Assumptions

Today’s Gremlin – “Assumptions” can get a planner or a supervisor into a lot of trouble. You might be very knowledgeable and have great faith in your trades-persons, but assuming they know what you know, can be dangerous. There’s always discussion about “how much detail” to put in a maintenance job plan. It should be safe to assume your trades know how to perform those basic skills that earned them their trade. But it is not safe to assume they are familiar enough with your equipment and operation to use those skills correctly.

Is RCM Necessary for All Assets?

Is RCM Necessary for All Assets?

True or False? Reliability Centered Maintenance (RCM) must be applied to all assets.

False!

In this video, we explore the flexibility of Reliability Centered Maintenance (RCM) and how it can be tailored to your specific needs. RCM doesn’t have to be applied to every asset; instead, your analysis scope should be driven by your goals. Whether you focus on a single piece of equipment, a specific component, or a select group of machines, the approach can vary. Join me as we debunk the myth that RCM must be applied to everything.

How to be ‘qualified’ in Weibull Analysis 

How to be ‘qualified’ in Weibull Analysis 

(and Why It Matters)

In the world of reliability engineering, few tools are as powerful – or as misunderstood – as Weibull analysis. It is a statistical tool, which can turn people ‘off’ straight away, as we can immediately leap to a list of equations and tables of numbers that we need to memorize and embrace. But Weibull analysis is different. You actually don’t need equations.

Check out the chart below, which is called a ‘Weibull plot.’ The different shapes and colours representing the failures of different components can tell us so many things without having to evaluate a single equation.

FMEA in Practice: Lessons Learned from Mistakes

FMEA in Practice: Lessons Learned from Mistakes

I usually write articles about topics I personally struggled to understand from the sources available to us such as books, online resources, and so on. I believe most technical concepts are fairly straightforward at their core, but the way we express ideas and translate our understanding into writing often makes them harder for others to grasp. That’s an area where we can all continue to improve.

As part of that journey, my goal with the Breaking Bad for Reliability newsletter is to be a communicator of Reliability Engineering principles, and I am doing this mainly for two categories of people: [Read more…]

Quality Objective 8: SPECIAL CHARACTERISTICS

Quality Objective 8: SPECIAL CHARACTERISTICS

“Always remember, your focus determines your reality” – George Lucas

In this article, I will outline how to evaluate an FMEA against the FMEA Quality Objective for identifying special characteristics. Special characteristics are often not well understood by FMEA teams, and yet have potential to be highly useful in FMEA applications.

REVIEW Analyzing Repairable System Failures Data

REVIEW Analyzing Repairable System Failures Data

Recently, Ziad let me know he published an article titled Analyzing Repairable System Failures Data in the April-May 2017 issue of Uptime magazine (subscription required). He suggested I’d be interested in the article since it provides a way to analyze repairable system data without using MTBF. He was right.

The article is a short description and tutorial on using mean cumulative plotting and function (MCF). While the article recommends staying away from using MTBF, it could be a bit of a stronger message. The article does provide a very nice worked out example illustrating the use of a mean cumulative plot. [Read more…]

How to Create a Healthy Organization

How to Create a Healthy Organization

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

Healthy organisations create an environment where organisational members have mutual trust and respect for each other, especially in terms of how they decide and implement decisions. They create an environment in which organisational members are empowered to deal with their problems and where problems can be identified, discussed, and solved with mutual trust and respect through cooperation and communication amongst themselves.

When there is mutual trust and respect, there will be more teamwork and collaboration. This constructive and collaborative culture will generate a positive ‘risk culture’ and a collaborative approach to risk management. It builds a higher level of risk maturity for the organisation.

Moving from Quality to Accuracy in Production and Maintenance 

Moving from Quality to Accuracy in Production and Maintenance 

The Accuracy Controlled Enterprise: Using Accuracy-Controlled 3T SOPs for Production and Maintenance Quality Assurance

 Reliable equipment is necessary to reduce production costs and maximise production throughput. High reliability from operating equipment requires high quality reassembly, coupled with the correct operating practices. You can guarantee correct maintenance and proper plant operation by specifying a target and tolerance in maintenance and operating procedures. 

Having a target and tolerance sets the recognised acceptance criterion. A simple proof-test will confirm if it has been met. Specifying a mark and tolerance range changes the focus from one of simply doing the job; to now doing the job accurately. This results in high quality trades’ workmanship and sound equipment operator practices that deliver reliable equipment performance. Those organisations that use ‘target, tolerance, proof-test’ methodology in their procedural tasks move from being a quality-conscious operation to being an Accuracy-Controlled Enterprise (ACE).
