Accendo Weekly Update #474 December 1, 2024

Progress in Field Reliability?

An article series by Larry George

Larry's goal: Work-related needs led to doing the best I could with available data,with help from employers, customers, and friends. I would like to share solutions and applications: multivariate risk analyses, optimal opportunistic maintenance, nonparametric reliability estimation without life data, design of ongoing reliability tests, assembly line buffer size and maintenance optimization, life tests without killing controls, multivariate reliability, and problems readers pose.

Thus an ongoing article series that explore how to tease out the most information from the available data.

RM157: What's On Your Workbench? Critical Steps to Avoid Contamination PCA's During the Rework Process

On today’s episode, we’ll be exploring the critical steps to avoid contamination on circuit assemblies during the rework process with our expert guest, Gayle Towell. [Listen here...]

Fundamentals of Early Field Results

Recorded 12 November 2024 / Fred Schenkelberg

At least one group called this the ‘Delta Phase.’ It is the period shortly after launching a product and provides a unique opportunity to reduce future field failures and improve customer satisfaction dramatically. The idea is to aggressively identify and resolve any field issues identified by your customers.

Let’s explore the concept of a delta phase and how to implement it in your organization. Plus, let’s examine a few situations that make significant short and long-term reductions in the field failure rate. [Listen here...]

What's Wrong with Using FITs?

Recorded 22 October 2024 / Chris Jackson

Every industry has its own way of characterizing reliability metrics. For example, the ball bearing industry uses the metric ‘B_10’ to represent the time by which they expect 10 % of all ball bearings of a specific type to fail. Electronic component manufacturers use the term ‘Failures in Time’ of ‘FITs’ to describe the reliability of their products. But what is a FIT? And how can you use it to measure reliability? Did you know that many electronic manufacturers advertise ‘FIT values’ that imply a mean time to failure of over 1000 years? If you are involved in electronic component reliability, this webinar recording is for you! [Listen here...]

Fundamentals of Ongoing Reliability Testing

Scheduled for December 10, 2024, at 9 am US Pacific time.

Speaker: Fred Schenkelberg

Ongoing Reliability Testing (ORT) is a class of product testing that aims to identify potential field reliability issues after product launch and before customers experience failures. Typically, done using a rotation of samples directly from production and using expected use conditions/stresses, the testing balances many factors to be of value.

ORT works well to monitor an ongoing production process subject to variation. If that variation impacts reliable performance, then a well-designed and implemented ORT should identify the issue.

Let’s explore the range of considerations when designing an ORT to optimize the ORT’s ability to identify field problems efficiently. We will also discuss the various tradeoffs that impact sample size, the use of accelerating stresses, and more.

Ten Things You Might Hear an Ineffective Reliability Professional Say

 A mid-level reliability engineer was disgusted, “Can you believe they didn’t ask me a single question? I knew they wouldn’t understand.” I have heard it so often that it inspired me to create the FINESSE fishbone diagram®. Improving our communication skills makes us better reliability professionals and respected trusted advisors.   ...[Read more…]   

DOE – What are You?

 The history of Design of Experiments (DOE) can be traced back to the work of various individuals, including Genichi Taguchi, a Japanese engineer and statistician. Taguchi made significant contributions to the field, particularly in the area of robust design, which aimed to improve the quality of products and processes. His work was influenced by the need for quality improvement in post-World War II Japan. Taguchi’s methodology, known as the Taguchi methods, was based on the concept of “robust parameter design,”    ...[Read more…]  

Hybrid Project Management Methodology

A Hybrid Methodology combining the speed and flexibility of Agile and the structure of Waterfall is feasible and practical. I base my opinion on the research I have done. I recently presented a Webinar to Project Management Institute (PMI) members on how to merge Agile and Waterfall to achieve a Hybrid methodology. The focus of this paper is to address the greatest risk to a company in implementing the new methodology i.e., acceptance of it.    ...[Read more…]

KPIs are a Big Lie About Performance Improvement

It is a mockery to use business performance indicators to manage a company or department. Using the informationthat shows up on the management dashboards on your screen can wreck your company. Measuring a process does not put you in control of it. A process is totally self-controlled. You always get what the process gives you.   ...[Read more…]

Reliability Analysis of life data with Multiple Failure Modes

 Dear friends, I am happy to release this video on reliability analysis of life data with multiple failure modes. The analysis procedure is illustrated fully in Minitab software with a real-life case study with six failure modes. The concept is that when a system fails for one failure mode at time t, this data of time is right censored data for other failure modes!   ...[Watch here…]

Reliability Starts Here: Why Every Role Matters

 Who’s responsible for Reliability? Spoiler alert: It’s everyone. Just like the intricate root system of mangroves 🌱, building a strong Reliability Culture involves every part of an organization working together. Discover how to involve every team member in creating lasting Reliability in my latest video from Key Largo, Florida.
