14 Ways to Acquire Reliability Engineering Knowledge
Maria Popova recently wrote about the work of James T. Mangan and his book You Can Do Anything!
, published in 1936. In particular she focused on one section titled 14 Ways to Acquire Knowledge
The article is about learning anything, which had me thinking about how to learn reliability engineering. So, without apology let’s explore 14 ways to learn about reliability engineering. [Read more…]
10 Steps of FMEA
In Chapter 8 of The Basics of FMEA by Robin E. McDermott, et. al. discusses the ten steps for an FMEA. I find it to be an excellent summary for describing and conducting a failure mode and effect analysis.
Therefore based on the work of McDermott and others, plus my own experience here are the ten steps with my descriptions. [Read more…]
Basics of Reliability Engineering
One of best features about working in reliability engineering is everything fails, eventually. This fact provides a bit of career stability.
Another aspect I enjoy is the concepts and approaches that create the foundation for reliability engineering knowledge do not change very much over time. The basics of reliability engineering are the same as when the earliest engineers began design structures and products.
How to Read a Standard Normal Table
One of the most basic skills needed for the CRE exam is the ability to correctly read the Standard Normal Table.
Writing this short how-to article would be really easy if there were only one way to create the table. There isn’t. It seems every author has to create a unique way to tabulate the values. [Read more…]
3 Ideas to Overcome Organizational Inertia
It seems the forces of nature are working against our ideas.
I recall being frustrated as a child playing in the sandbox. I wanted to create a ramp of sand to race my cars down. No matter how much I pushed and patted the dry sand succumbed to some unseen force and did not hold the desired shape.
In business, we sometimes experience the same frustration. It’s not gravity.
Instead, we are facing organizational inertia.
Role of Reliability in an Organization
An effective product reliability process requires a strong team, at every level.
The team of employees within an organization that participate and impact product reliability is a vast and widespread group of people. They include members of the design team, design managers, quality and reliability engineers and managers, procurement engineers and managers, warranty managers, failure analysis specialists, members of the marketing and sales staff, members of the finance and manufacturing teams, and field service and call center staffs.

11 Ways to Find Reliability Value
Most agree that improving products or process reliability is a good thing. It’s good for customers, factories, and our business.
And, sometimes it’s difficult to answer the question,
What is the value of that reliability activity?
Years ago my boss asked me what value I provided the organization. Working as a reliability professional, I thought that my value was obvious. He asked me to show the value.
It was harder than I thought.
Calculate Weibull Mean and Variance
For our use of the Weibull distribution, we typically use the shape and scale parameters, β and η, respectively. For a three parameter Weibull, we add the location parameter, δ. [Read more…]
Finding Value in FMEA
Failure modes and effect analysis (FMEA) is a tool that works to prevent process and product problems before they occur.
I like to define FMEA’s as an organized brainstorm. The process examines a product or process and asks what could go wrong. Then the team systematically determines and rank orders for each failure mode:
– the severity of the problem when it occurs
– the probability of the problem occurring
– the ability to detect the problem before it occurs
Good design engineers think about how the design could fail and improve the design. FMEA provides a structured team approach to further improve the design.
Top 10 CRE Exam Preparation Tips
My best CRE exam preparation tips
Over the past few years, we have been helping people from around the world prepare for and pass the ASQ CRE exam. Over this time, and from personal experience, I’ve learned a few things about what makes a difference.
Here are ten tips to help you prepare. [Read more…]
Consider Reliability Prediction Value
One of the primary questions we answer as reliability engineers is:
How long will it last?
Reliability prediction is the forecast or prognostication attempting to quantify either the time till failure, or expected future failure rate or warranty claims, or required spare parts.
We need to know as we make decisions today about the design or purchase.
Recipe for CRE Exam Preparation
In a recent discussion in the Linkedin group ASQ Reliability Division, John Pagendarm replied with his recipe for CRE exam preparation. With John’s permission, I’m posting here.
When Are We Out of Control
For a stable process, nothing much happens. If the stable process is producing acceptable products, we should expect to continue to produce acceptable products.
Unless something changes. [Read more…]
2013 in Review
Thanks to you all for a great year. The idea of the blog is to assist those preparing for the CRE exam or wanting to learn about reliability engineering. It seems to have found the audience.
The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.
Here’s an excerpt:
The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 21,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 8 sold-out performances for that many people to see it.
