I recently received a question about the artwork found at Accendo Reliability. “Why castles?” So, I provided an answer and thought I would share it in this webinar. Also, let’s talk about how and why Accendo Reliability got started and how it’s been doing over the past ten years. [Read more…]
We do not “do reliability”. “Reliability” doesn’t just happen to a product – well, it does with or without our intervention. To achieve the stated reliability objectives for a new product or production line, we can trust to luck or sort out what needs to happen to realize the objectives. [Read more…]
One role reliability engineers enjoy is that of analyzing data. We have available to us a wide range of statistical methods, yet each does require some form of data. In some cases, we are data rich with almost too much data. In other situations, we are lacking data or have insufficient data.
During the interview, I turned down a job when I learned the hiring manager expected me, a potential new reliability engineer on the team, to only conduct tests. Creating and assembling a reliable product or service takes more than testing. [Read more…]
In the past two months, I’ve received a few questions concerning why I recommend avoiding using MTBF or similar metrics. I’m also moving the articles I and others wrote on the topic from NoMTBF.com to Accendo Reliability. So, the topic of MTBF has been on my mind.
This morning’s email included a question on why I was so against using MTBF. This event is my answer. [Read more…]
When first charged with designing, conducting, and analyzing an ALT, I didn’t even know there was such a thing as accelerated life testing. Along with the assigned task was the expectation that I would learn what was necessary to design, conduct, and analyze a suitable ALT. I like those kinds of tasks – one where I must learn to succeed. [Read more…]
Over the past few months, we’ve received some questions about accelerated life testing. There are bound to be more questions as ALT can be confusing to plan, conduct, or interpret. Let’s get together and address your questions related to ALT. [Read more…]
Creating a plan and generating information is part of reliability engineering, yet it’s not enough. To be a successful engineer, one must communicate well. This means we need to write, discuss, and present well. We are often called upon to examine failures and recommend solutions, examine a dataset and explain the finding, or conduct an experiment and detail the results. [Read more…]
A key element of reliability engineering is doing the right thing at the right time. When running an experiment or test, conducting an assessment, or performing an analysis, the method we use must fit the situation. Being busy does not add value; getting meaningful results does. [Read more…]
This is an overview of the six steps to achieve high reliability from Carl and Fred’s book. Creating and executing a reliability plan that assists the team in designing, manufacturing, and supporting meeting reliability objectives takes effort. Let’s discuss the details of that effort so that you can focus on the critical steps. [Read more…]
Once word got out that I was taking graduate-level courses in statistics, I dreaded the knock on the door. Colleagues, some of which I knew and others from some far reach of the company, would ask if I could take a look at their data. I didn’t learn the necessary first steps with a stack of data in class.
I’ve lost count of the number of data sets I’ve reviewed and analyzed. I know there are important considerations and questions before creating the first plot. Let’s review the essential first steps you should take when presented with data.

We have many options to learn reliability engineering—books, magazines, newsletters, conferences, seminars, etc. We have options. Some options are better than others, depending on what you want to know. Likewise, some options are better than others, depending on what you want to share.
After 30 minutes of being on hold, I wasn’t sure what to expect from customer service for a product reliability issue. The scratchy soundtrack didn’t foretell a great experience either.
Once connected to a company representative, we resolved the issue quickly and satisfactorily. Unfortunately, that was a pleasant surprise. All too often, the frequently repeated “Your call is important to us.” (an Amazon affiliate link) just isn’t true, in my experience.
Did you know that customer service can add significant value to an organization, especially when product reliability doesn’t meet customers’ expectations? Besides providing the team with valuable product reliability performance information for past products, the service team can improve customer loyalty.
[Read more…]When working with a team creating a new system, I always ask, “what is the goal?” The answers often do not make much sense. The team using SMART reliability goals are astonishingly well-stated.
The difference that makes a goal, objective, or requirement practical and useful is summed up by SMART. A SMART goal is Specific, Measurable, Achievable, Relevant, and Time-bound. Let’s explore each element as related to a reliability goal.

While I’m not much of a New Year’s Resolution guy, I guess I’ve set a resolution. I need to restart writing weekly articles for Accendo Reliability.
The thing is, I struggle to write. Plenty of other interests and tasks keep me away from the keyboard. Yet, as I explained to a few new authors how writing and posting on Accendo Reliability is a good thing, I realized I have been putting off hitting the keyboard again.
Over the past few weeks, I’ve explained to those interested in writing articles about the virtuous circle created by having many authors contribute articles, which increases interest, engagement, and traffic to those articles, which further increases the reach of those articles. Of course, this is just one reason, and there are others, plus plenty of hurdles to overcome.
