What MTBF Do You Want?

What MTBF Do You Want?

Originally published in the ASQC Reliability Review, Vol. 15, No. 3, Sept. 1995 pp. 23-25 

This article shows reductio ad absurdum in action. Yes you can achieve any MTBF you want, by mixing products with Weibull life distributions, but you won’t want the consequences. The article also shows the absurdity of specifying MTBF, alone.

Mental Risk: Solitude is Pleasant: Loneliness is Not

Mental Risk: Solitude is Pleasant: Loneliness is Not

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

Mental Health Awareness week is fast approaching. This year [2022] it is from 9th-15th May, and the theme is Loneliness, Anna Neagle is right, in her book Cultivating and being happy in our own company is important, but even the most introverted among us benefit from human connection and where increasingly people have started working from home, or in a hybrid home/workplace setting, we need to proactively seek that connection out.  Connection can be with our close circle, or even from small talk with strangers the research shows that both are helpful for our well-being.

Maybe you’re new to a city and struggling to make friends. Or the people you love seem to be in a different phase of their lives than you are. Or you’ve got all the friends you could possibly want, but you still don’t feel connected. At one time or another, everyone has felt lonely. It’s just one      of those things that happens sometimes. The hard part is dealing with loneliness when it overcomes you.

“It’s something every human being has gone through or will go through, In fact, a study analysis in Perspectives on Psychological Science suggests this feeling is involved in everything from depression and alcoholism, to strokes, decreased immune system, and early death, Here’s how to     deal with loneliness when you inevitably get hit with the blues.

  1. Create a list of activities you can do by yourself.

Ironically, if you only ever try to cure your loneliness by surrounding yourself with people, it can be remarkably short-lived. “As soon as that person leaves, you’re lonely again,” Instead, have a list of simple activities you enjoy or would be willing to try when you’re lonely: a puzzle, playing on your phone, crocheting, quilting, watching movies, painting, screenwriting. The goal is to distract from the acute loneliness in a healthy way

Better yet, date yourself, says Kate Balestrieri, a licensed psychologist in Los Angeles, California. “We can use [loneliness] as an opportunity to get to know ourselves better,” she explains. Take yourself to dinner, a movie, the park, a museum, a place you’ve always wanted to go. Many people look to relationships to regulate their emotions, Balestrieri says, and feeling lonely can be an opportunity to learn to do that for yourself.

  1. Look for activities where you can be alone with other people.

Think Meet Up groups, library clubs, city events, and so on, If you can establish a new hobby that puts you with like-minded people, even better. Always wanted to hike or paint or learn photography? Look for classes or groups that are welcoming to beginners. The goal is to find a place where you’ll be around people, even if you’re not necessarily making friends. If you happen to meet somebody great there, even better.

  1. Make a list of the people you can be with when you’re lonely.

Is it a friend, family member, or an acquaintance who keeps things positive? Give yourself a list of people to lean on when you feel like you don’t have anyone to talk to. You want to keep your options open, Dr. Bill Pomfret says, so list as many as you can. Avoid leaning on a single person, if you can  it can put too much pressure on the relationship and leave you reeling if they’re not available when you call.

  1. Try to be social sometimes — even if you don’t feel like it.

Does the idea of talking to new people make you break out in a cold sweat? That’s not unusual. Loneliness has a way of making social interaction seem pointless. “At some point, you just have to make yourself do it,” Pomfret says. Daily affirmations, like positive “I” statements, could help. “I am interesting, I have things to offer, I am not afraid of rejection” are a few good examples, Pomfret says.

  1. Try giving back.

Maybe it’s volunteering to play with cats at the local animal shelter, dog walking, serving meals at a homeless shelter, or visiting people in nursing homes. Contributing to your community in a way that feels good can be wonderful for loneliness. The interactions can help build positive connections with new people — or pets — who are happy to see you, without leaning too heavily on a friend group, Pomfret says.

  1. Find a way to move your body that you enjoy.

It’s not so much about exercise as it is about getting in touch with your sensory system, Pomfret says, which can encourage a state of connection and flow. “What you’re trying to do is engage your body and engage your mind out of the loneliness,” he explains. Surfing, playing soccer, sailing, walking barefoot in sand or grass — all of these can help you pay attention to the sensations in your body.

  1. Consider going to therapy.

Even if you’re skeptical of therapy’s other values, it can be helpful for loneliness simply because you’re being heard and valued and gives you someone to talk to. “Sometimes it’s just about somebody listening to you,” Pomfret says. “And that’s very important.”

  1. See if your company has an Employee Assistance Program (EAP).

If you’re looking for help but you don’t totally know where to begin, check to see if your employer has an EAP. Often, they will offer free or discounted benefits that include access to counselors and therapists who can help you work through your loneliness.

  1. Take a social media break.

Social media can bring people together, but it can also make people feel terribly lonely, and experience FOMO, or Fear of Missing Out. A study from the University of Pennsylvania that was published in the Journal of Social and Clinical Psychology found a causal connection between  social media use and feelings of depression and loneliness.  So, know that if your social media is making you feel more distant than connected, you’re not alone. Consider deleting the apps from your phone and giving yourself a break.

  1. Get some sunshine.

It might seem silly but getting out in the sunshine and fresh air can do wonders for your mental health. Getting sun can trigger your body to produce endorphins and serotonin, which have positive effects on how you feel. Of course, remember to wear sunscreen.

  1. Remember loneliness is temporary.

Even if you’re feeling lonely now, that doesn’t mean you’ll always feel lonely or you’ll never find a community that nourishes you. “You are the architect of your future,” Pomfret says. “You get to go out and make new bonds.” he adds that absolutely everyone has something to offer in relationships. You’ve just got to go out and create them.

One of the quotes I use on a regular basis is,

“There is little difference in people, but that little difference, makes a big difference, the little difference is attitude, the big difference is whether the attitude is positive or negative”.

Last year I wrote an article “Avoiding Loneliness when working from home” and if you would like a free copy of our PDF which you can use internally to educate your teams on simple steps, they can take to manage this proactively. Alternatively if you are looking for a talk either face to face or online about why human connection is important and why we need to look more proactively at managing this in our lives we do have a few slots still available that week and I can talk you through the session before hand to see if you can see value in it for your workforce.

A poet is a nightingale who sits in darkness, and sings to cheer its own solitude with sweet sounds,

Bio:

Dr. Bill Pomfret of Safety Projects International Inc who has a training platform, said, “It’s important to clarify that deskless workers aren’t after any old training. Summoning teams to a white-walled room to digest endless slides no longer cuts it. Mobile learning is quickly becoming the most accessible way to get training out to those in the field or working remotely. For training to be a successful retention and recruitment tool, it needs to be an experience learner will enjoy and be in sync with today’s digital habits.”

Every relationship is a social contract between one or more people.  Each person is responsible for the functioning of the team.  In our society, the onus is on the leader.  It is time that employees learnt to be responsible for their actions or inaction, as well.  And this takes a leader to encourage them to work and behave at a higher level.  Helping employees understand that they also need to be accountable, visible and communicate what’s going on

How Defining Functions Shapes Your Reliability Strategy

How Defining Functions Shapes Your Reliability Strategy

Understanding RCM

Hi everyone, I’m Nancy Regan, and in today’s video, I’m breaking down what makes Reliability Centered Maintenance truly “Centered.” Using a real-life example from my own vehicle—where my fan only works on level four, causing all sorts of noise issues—I explain how defining the function of an asset is the key to understanding its reliability needs.

I walk through how writing Functions is the foundation of the RCM process, ensuring assets are maintained to meet the specific needs of their operating context. From there, I explain how this noisy fan failure creates non-operational consequences in my case, and why, in this situation, it’s okay to run this particular Failure Mode to failure. What does the “Centered” in Reliability Centered Maintenance mean? Watch to find out!

Distinguishing NPI Materials Management from Project Management

Distinguishing NPI Materials Management from Project Management

A sometimes overlooked function of production planning, is materials management for new product introduction (NPI).

In our previous article, we covered fundamentals of managing contract manufacturers (CM) value streams.  The goal for NPI is similar: we want NPI prototypes available per a prototype plan and (eventually) a production plan.

Below is a simplified value stream map for a managing a contract manufacturer using “plan, source, order, make, deliver” as major subprocesses.  The planning function “NPI Materials Manager” is shown with corresponding interfaces and is the focus of this article.

The Answer That’s Clear, Simple, and Wrong

The Answer That’s Clear, Simple, and Wrong

H.L. Mencken, the sharp-witted satirist and critic of early 20th-century American life, once wrote, “For every complex problem, there is an answer that is clear, simple, and wrong.”1 Mencken, born in Baltimore in 1880, was known for his incisive critiques of societal norms and his skepticism of simplistic solutions to complex issues. 

Mencken’s wisdom applies to both everyday life and technical fields. His insights are particularly relevant in the engineering, manufacturing, and reliability disciplines, where the temptation to seek easy answers can lead to costly errors. We’ll start with a relatable everyday example before exploring documented cases in engineering and manufacturing that demonstrate the pitfalls of oversimplified solutions.

The Origins and Power of the FINESSE Fishbone Diagram for Reliability Engineers

The Origins and Power of the FINESSE Fishbone Diagram for Reliability Engineers

You get a few raised eyebrows when you claim to be Communicating with FINESSE. Well, at least you do if the person on the other end does not understand that FINESSE stands for something. Or if they do not understand what a fishbone diagram is. Here’s a short review of the origins of FINESSE and how the FINESSE fishbone diagram powers the communication of reliability engineers.

Agile EVM Based DOD Software Development Project WBS

Agile EVM Based DOD Software Development Project WBS

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

“Department of Defense (D0D) acquisition must improve program while working within budgetary constraints. The DoD community shows an interest in utilizing Agile methodologies, but struggles to reap Agile’s benefits. They encountered challenges including the historically built-up processes that enforce heavy-weight oversight, the outdated, manufacturing focused Work Breakdown Structure (WBS) provided in DoD Handbook: Work Breakdown Structures (WBS) for defense Material Items (MIL-STD-881C), and the inability of traditional waterfall-based process to accommodate iterative development.

 Fundamentals of Vibration Measurement and Analysis Explained 

 Fundamentals of Vibration Measurement and Analysis Explained 

Thanks to Peter Brown for this article.

1. Introduction: 

The advent of the microprocessor has enormously advanced the process of vibration data acquisition and analysis in recent years. Measurement tasks that took hours only two decades ago can now be completed in minutes and better decisions made because of better data presentation. 

However, the basic processes of measurement and analysis have remained essentially unchanged, just like the machines from which the vibration is measured. The results of the measurement and data analysis need to be compared with known standards or guidelines and decisions made as to whether the machine is acceptable for service or maintenance should be planned. Increasingly these processes are being handled electronically but we are still a long way from replacing the fundamental knowledge and experience of the vibration analyst. 

In this article we will review the basic principles of vibration measurement and analysis in order to lay the foundation for capable fault diagnosis to be considered later.

Will you Accept a “No Brainer” Opportunity?

The “no brainer” opportunity

Imagine, 6 operational locations with a combined maintenance spend of $438 million and acceptable but mediocre performance. Production outputs ranged from 70% to 94% of nameplate values.

  • The cost savings potential is $97 million.
  • Improvement to nameplate levels adds upwards of $768 million in revenues.
  • The spend to achieve that over 3 to 5 years was only $30 million.

That’s faster than the current mine permitting processes. Revenue was equivalent to adding a new mine at about 3% of the typical capital investment. Yes, this was a real customer in the mining industry with operations throughout North America.

Condition Based Maintenance vs. Preventive Maintenance Tasks

Condition Based Maintenance vs. Preventive Maintenance Tasks

Finding the Best with RCM

Hi everyone, I’m Nancy Regan, coming to you from the Watermelon Festival in Russellville, Alabama! In today’s video, I talk about how Reliability Centered Maintenance (RCM) can help you find the “sweet spot” when choosing proactive maintenance tasks for your equipment.

Just like every watermelon has a sweet spot, RCM helps you pinpoint the best maintenance task for each Failure Mode. Using a simple example like “oil degrades due to normal use,” I explain how RCM guides you to decide between different options, such as Scheduled Replacements or Condition Based Maintenance. By answering the RCM questions, you can figure out which task is the most cost-effective or reduces the risk of failure to an acceptable level.
