Announcements & Reminders
I received a nice comment this week: "Hi Fred, hope you are doing well. First of all, I wanted to tell [you] that Accendo Reliability is a perfect source of information. I really appreciate your time and effort on that. I refer to different articles, webinars almost every week." ?And received two questions, too: One on using time vs cycles and the second on system modeling approach with complex states.
If you have a question or compliment, send it over.
Stay safe, stay flexible, and stay resilient.
Cheers,
Fred
PS: How about a location on Accendo Reliability just for questions and answers? It would be like an FAQ, yet listing all questions received. It might be a long list. I will?have to think about how to organize it.

Fundamentals of Safety Margins
One way to create a robust product or system is to consider all the stresses and design to withstand those stresses. We often do not know all the stresses, magnitudes, and ranges of variation. We know that many materials degrade with time, yet we do not know precisely how much or how fast. We also do not know what new stresses may arise or how stresses will change over time.
How to Get Unstuck
In this presentation, Greg Hutchins will explain how to Get Unstuck: Do Good. Be Happy – based on the Working It book (4.9/5.0 stars on Amazon). Today’s Linkedin review: “A wonderful book by a great author. A must recommend for those who are looking to enhance their skills in the VUCA world.” ~Ankur Tyagi
Reliability of a 'K out of N' System
We often use the term ‘system reliability modelling’ to describe any scenario where we need to somehow convert what we know about component reliability into system reliability in order to make a decision. Some of us might have heard of ‘series systems’ that have no redundant components, meaning that the system fails when any component fails. Then there are ‘parallel systems’ where the system fails when the last component fails. But then there are ‘K out of N’ systems that need ‘K’ components out of a total of ‘N’ components to work for the system to work. Do you know when ‘K out of N’ system reliability looks like series system reliability?

The MTBF and Modeling System Reliability?
Scheduled for March 26, 2024, at 8?am?US Pacific time.
Speaker: Chris Jackson
The Mean Time Between Failure (MTBF) appears in lots of textbooks and standards, so it must be really important … right? Well, not really. The MTBF is the most overused and misunderstood term in reliability engineering, including system reliability modeling, where we can find textbooks and standards with equations that allow you to calculate system MTBF from component MTBFs. If you are unsure why the MTBF is bad, especially for system reliability modeling, then join us for this webinar, where we will illustrate with pictures (not equations) what the MTBF is and how bad it can be to focus on it as a reliability performance metric.

AI Product Development and Deployment
领英推荐
Scheduled for April 2, 2024, at 9?am?US Pacific time.
Speaker: Greg Hutchins
Greg will discuss the critical architecture and design practices that need to be considered in AI product development and deployment. Why should you attend? AI knowledge, skills and abilities are now recognized as a prerequisite for continued employment, development, and promotion for ALL knowledge workers.
In this webinar, Greg will discuss:
? What is an AI product? ? What are the requirements for AI integration into products and services? ? What is the state of AI product development? ? What are the 3 key questions in AI product dev? ? What is the lens for understanding AI product dev? ? What can quality and reliability professionals do NOW to understand AI product dev and increase their employability?

Fundamentals of Control Charts
Scheduled for April 9, 2024, at 9?am?US Pacific time.
Speaker: Fred Schenkelberg
On one of my first vendor visits, they proudly showed us the control charts behind glass near the conference room. They were nicely printed, all in perfect control, and rather odd. A control chart belongs on the production line, where the operators make the measurements. They are of little value when automatically collected and printed out once a month for display-only purposes.
Statistical control charting (SPC) is a method for monitoring and determining whether a process is in control or stable. It permits the team to identify opportunities for process improvement and provides the necessary evidence that a process is in control, if it actually is, as a prerequisite for calculating process capability.
Let’s discuss control charts and how best to employ them. We will also examine how valuable an SPC program can be for the organization and customers.

Boeing is Steering Harder into its Spiral of Death
Boeing has somehow managed to make the bad public relations created by those pesky onboard batteries catching fire in 2013 practically disappear. Not through good management. But through a never-ending series of disasters and catastrophes that shows no sign of letting up which is dominating Boeing’s news cycle that there is no remaining airtime for missteps like those battery fires. ? ?...[Read more…]

The Language We Use Matters
During RAMS this year, Wayne Nelson made the point that language matters. One specific example was the substitution of ‘convincing’ for ‘statistically significant’ in an effort to clearly convey the ability of a test result to sway the reader. For example ‘the test data clearly demonstrates…’
As reliability professionals let’s say what we mean in a clear and unambiguous manner.? ?...[Read more…]

Statistical Tolerancing using Monte Carlo Simulation
One of the weak areas in designing parts is deciding tolerances of various parts. Most engineers are familiar with Arithmetic Tolerance stack up analysis wherein they check impact of maximum and minimum values of various tolerances on assembly of parts. However, this can often result in high manufacturing cost. Thus, it may be more appropriate to analyse tolerances using statistical tolerance stack up approach. This can be performed using Monte Carlo Simulation. ? ?...[Read more…]
