True or False? The RCM Facilitator is responsible for checking the technical validity of the RCM Working Group’s answers to the RCM questions.
False! In this video, we explore the true role of the RCM Facilitator, highlighting their responsibilities and why they should not be an expert on the equipment being analyzed.

Dear friends, we are very happy to release this video on the first day of the World Quality Month 2023! Some of you have asked the question about how the formula for success run theorem was derived! You should find answer to that question in this video!
Also, the previous video shows the sample size calculation using template! However, in this video, Hemant Urdhwareshe, Fellow of ASQ, explains the mathematics of it and also illustrates how to perform sample size calculations using Microsoft Excel!

Did you notice the speed limit signs in your neighborhood today?
If like me, you went about your commute or regular travels relatively blind. You watched for the neighbor’s dog that jumped into the road last week, yet didn’t register seeing the speed limit sign.
It’s a cognitive burden to notice the mundane or known. [Read more…]
In the push toward digital transformation, automated inspection, and AI-enabled quality systems, it’s easy to overlook the fundamentals that quietly hold everything together. Among them are two terms that are frequently confused, even by seasoned professionals: Calibration and Verification
These words live at the core of measurement assurance, and understanding the difference isn’t academic; it shapes risk decisions, audit outcomes, and ultimately, product quality and reliability.

In the bustling Boeing factory in Seattle Engineers work diligently on the 737 Max. Alex Carter an engineer notices discrepancies in the AOA sensors test results. His concerns are overlooked amid the pressure to meet production deadlines. In a Sleek boardroom, senior executive Mark Thompson stresses the importance of production targets. Discussions over the MCOS system reveal it relies on a single AOA sensor prompting safety Advocate Sarah Lee to voice her concern.

A RELIABILITY IMPROVEMENT POLICY IS A DOCUMENT CONTAINING A SET OF PRINCIPLES TO GUIDE DECISION MAKING AND ACTIONS. IT TELLS HOW RELIABILITY WILL BE ACHIEVED IN AN OPERATION. IT COVERS THE WHOLE ASSET LIFE CYCLE AND SAYS WHAT WILL BE DONE AT EACH PHASE TO DELIVER RELIABILITY.

Unfortunately, we have been operating in a crisis manner without a reliability improvement policy. Have you samples of a Reliability Improvement Policy that I can use as a basis of crafting one for my organization — do you have anything to share?
As I have stated in the past, the materials you post have been a big blessing to my work. You have definitely empowered me with great information that I see changing the way people work.
Hello Friend,
Industries using machines require them to run reliably (no failures or unplanned stoppages) with high availability (ready for immediate use) and high utilization (continuously in use) all their working life.

People conclude what is expected of them is based on cues received from the forces that they face daily. These forces drive what they believe and how they should behave – in either constructive or defensive ways. These behaviours can either enables or inhibits effective risk management.
These forces also influence how people:
The attitude towards risks and risk management varies from person to person, from unit to unit, and from stakeholder to stakeholder. It can also be influenced by social context and surrounding culture.

Getting the right parts for your maintenance isn’t quite as easy as you might think. To begin with they must be included in your spares inventory and stocked on your site. If not, they must be purchased when needed. If you are reacting to a breakdown, you will need them in a hurry, and you may find yourself short. Why does that happen? And, what can you do about it? Missing parts can cost you time – time that the equipment is down and not producing. Your operators are idled and your supply chain folks are scrambling to help you. That increases maintenance and operating costs, reduces production output and reduces available working capital. Those parts are like gold to your operation!

In this video, I reveal one of the most common mistakes people make when writing Failure Modes in a Failure Modes and Effects Analysis (FMEA).
Too often, people confuse Failure Modes with Failure Effects, leading to wasted time and ineffective results. But don’t worry! I’ll show you how to avoid this by asking one simple question: “What specifically causes…?” This technique helps ensure you develop proactive strategies that improve equipment reliability, avoid unexpected downtime, and strengthen your overall maintenance plan

The power of a strong team cannot be overstated. Teams drive innovation, solve complex problems, and deliver results that no individual could achieve alone. Yet, successful teamwork doesn’t happen by chance—it requires intentional effort through team building.
Team building is the art and science of creating connections, fostering collaboration, and aligning individuals toward a common goal. While it’s often associated with trust falls and icebreaker games, effective team building goes far beyond these surface-level activities. It focuses on strengthening relationships, improving communication, and establishing a shared sense of purpose.

Dear friends, we are happy to release this interesting video to explain and illustrate the relationship between sigma level and process capability indices Cp and Cpk! Hemant Urdhwareshe, ASQ Fellow and Six Sigma Master Black Belt, explains this relationship with animations! We are sure, you will find this video interesting and useful!

Progressive improvement beats delayed perfection. Mark Twain
In this article, I will outline how to evaluate an individual Design FMEA or Process FMEA against the FMEA Quality Objective for design improvements.
An essential part of FMEA procedure is for the FMEA team to recommend and implement actions to reduce risk to an acceptable level. For Design FMEAs, this includes actions to improve the product design. For Process FMEA, this includes actions to improve the design of the manufacturing or assembly process. Of course, there are other types of actions that can be recommended, such as test improvements; but this quality objective is focused on design improvements. [Read more…]
I generally write articles about topics I personally struggled to understand from the sources available to us, such as books, online resources, and so on. I believe most technical concepts are fairly straightforward at their core, but the way we express ideas and translate our understanding into writing often makes them harder for others to grasp. That is an area where we can all continue to improve.
As part of that journey, my goal with the Breaking Bad for Reliability newsletter is to be a communicator of Reliability Engineering principles, and I am doing this mainly for two categories of people:
This may seem an odd article for the NoMTBF site. Stay with me for a moment longer.
Over the years of speaking out on the perils of MTBF, there has been some pushback. A few defend using MTBF. Here are three of the most common (maybe not exactly the best, per se) reasons to use MTBF. [Read more…]
To design more reliable electromechanical components and delay wear out, several strategies can be employed, focusing on material selection, design principles, and reliability testing.
– Hardness: Selecting materials with high hardness can resist wear from abrasion and erosion. For example, ceramics like alumina (Al2O3) and silicon carbide (SiC) are highly resistant to wear and are suitable for components exposed to abrasive environments. [Read more…]
