We establish reliability goals and measure reliability performance.
They are not the same thing. Goals and measures, while related, are not the same nor serve the same purpose. [Read more…]
The Relationship Between Reliability Goals and Confidence
Program Communication Management: Really?
Guest Post by Malcolm Peart (first posted on CERM ® RISK INSIGHTS – reposted here with permission)
Communication…dictionarily is the imparting or exchanging of information by speaking, writing, or using some other medium. It’s essential to humankind and allows us to live, work, trade and co-exist. It’s the basis of society, culture and civilizations and through communication there’s understanding and establishment of common beliefs.
Communication allows us to impart information, clarify such information and rectify misunderstandings. Of course, if miscommunication occurs and is acted upon then mistakes may well happen, and these mistakes can then cause problems. In Project Management such mistakes often result in delays, cost overruns, quality shortfalls, disputes and, possibly, project failure.
[Read more…]Do You Have a “Rich” or a “Poor” Person Mindset?
Demographic shifts in the workforce have given us “younger” companies with less experience and little guidance other than the way we were “raised”. Has the way you were raised left you with a mindset that is getting in your own way?

My brother-in-law, who worked for Japan Airlines (JAL) at the time, tells a story of watching Japanese aircraft maintenance technicians overhaul a JAL airplane jet engine. He tells this story because it is so unusual. During his visit to the maintenance hanger he was enthralled by the extraordinary maintenance procedure that the JAL technicians followed.

Chapter 4: Difference between Agile Hardware and Agile Software
In the previous chapter, how markets and global needs can impact your product was discussed.
In this chapter the differences between agile Hardware and Agile Software are explored to allow you understand how to apply agile techniques to a hardware development workflow.
The desire to gain a competitive advantage by releasing products faster has driven the widespread adoption of agile software methodologies. More recently, a push to apply agile techniques into the hardware development process has yielded mixed results, This is because electronic hardware products cannot be tested until complete subassemblies are built, and so important modifications to the product realization process are necessary.
[Read more…]Time-based VS Meter-based PMs
Time-based PM variation.
- PM1 and PM2 are for identical assets
- When FMEA was completed on these assets, it was determined that an inspection PM must be done every 30 days or 30,000 cycles.
- The decision was made to go with time-based PM’s. You let your technicians schedule their own work. They are assigned the PM at the beginning of the month and have till the end of the month to complete.
- You may be PM compliant, but not FMEA compliant.
My First Maintenance Lesson Exposed a Major Reliability Pitfall
The First Maintenance Lesson I Ever Learned—and How It Applies to Reliability Today
In today’s storytime, I’m sharing the first maintenance lesson I ever learned, back when I was eleven years old and eager to change the oil in my father’s car. As you’ll see, this experience taught me a valuable lesson about quality assurance and accountability—and it reveals one of the biggest mistakes many Reliability Teams make today.
[Read more…]Integrating Human Factors with Traditional Reliability Techniques
In Part 1 of Beyond the Numbers, I reflected on why Human Factors matter in reliability engineering and how the human element of the system can be overlooked by traditional hardware-focussed approaches.
This article explores how Human Factors principles can be integrated into traditional reliability analyses such as Reliability Block Diagrams (RBDs), Fault Tree Analysis (FTA) and Failure Mode, Effects and Criticality Analysis (FMECA) and without reinventing the wheel or introducing additional complexity.
The short answer is that we are already doing much of this implicitly. Applying Human Factors principles makes those assumptions explicit and therefore visible, challengeable and open to improvement. [Read more…]
Top Reliability Engineers Make Risk Management Simple for Every Frontline Worker
Think about the greatest risk you have encountered in the past five years. Maybe it was related to physical injury or serious sickness. It could be related to the mental health of a family member. Natural disasters or career changes are obvious ones. In fact, you can probably think of more than one great risk you have recently experienced.
Now, what is the definition of risk? In technical sessions and my workshops, well-educated business professionals struggle with the terminology. It usually takes two to three minutes for someone to arrive at their definition. The sad news is that there are about as many definitions as there are well-educated people in the room.

Just when I thought we had experienced every possible MTBF definition confusion, here’s another.
This one is courtesy of the thread concerning the impact on reliability when adding redundancy to a system. [Read more…]
Reliability Test can be Done in Parallel to Design Validation?
Yes, reliability testing can be done in parallel with design validation (DV). This approach has both advantages and disadvantages, which are important to consider in the context of product development and testing.
Safety Culture and Artificial Intelligence
Guest Post by Bill Pomfret (first posted on CERM ® RISK INSIGHTS – reposted here with permission)
Since the 1990s, organisations have attempted to improve safety culture. They have tried top-down approaches, with senior management making statements about how important safety is. They have tried bottom-up hearts and minds programs, encouraging workers to work safely, and stop if a job can’t be done safely. There have been great strides, and examples of success, such as the UK 2012 Olympic development.
However, many safety culture programs stall after some initial improvements. Senior managers have invested in the program. Workers on the frontline want to be safer and healthier. Sometimes the obstacles come from the middle managers and supervisors, who are invested in existing ways of doing things. For a busy manager there just isn’t time to get ahead with improvement programs while they are doing the day-to-day supervision and management tasks.

Maintenance Strategy 202: Develop your equipment maintenance strategy, then develop your equipment maintenance programs
First develop maintenance strategy—what you want to achieve with your equipment maintenance, why it is necessary, and how to do it.
Then turn strategy into the plans to maintain production asset reliability with the equipment maintenance program.
Often maintenance managers and maintenance engineers are asked to develop a maintenance strategy for their plant and equipment. They need to develop a document. In it you explain how you are going to use the least plant and equipment maintenance expenditure and efforts to ensure the necessary production performance from your production plant and equipment.
[Read more…]The Field Reliability Applications Award
From ASQ Reliability Review, Vol. 16, No. 3, Oct. 1996. Revised 2002, 2018, and Jan. 4, 2026.
The Apple Computer Reliability Department manager, Wayne Smith, told me (circa 1991), “We make sure Apple doesn’t sell a product that doesn’t work,” (by in-house product tests during design phase). (I worked in Apple’s Service Department.) Testing helps, but real, age-specific reliability is determined in the field, in the hands of customers, in their environments. Companies could benefit from using age-specific, field reliability to eliminate waste, improve customer satisfaction, and reduce uncertainty. The Field Reliability Applications Award is a clone of the Malcolm Baldrige National Quality Award modified to quantify reliability maturity. The field reliability applications evaluation in this article supplements Fred’s podcast on “Reliability Maturity” [Schenkelberg].
[Read more…]Your Warehouse is Either a Goldmine or a Graveyard
It’s 2 AM. Your SAG mill gearbox just failed. The plant is down, losing $95,000 every hour. You call the warehouse: “Do we have a spare?”
That answer could mean the difference between a 4-hour repair and a 4-week nightmare waiting for an emergency shipment from overseas. The frustrating thing is, someone made a decision months or years ago about whether to stock that gearbox. They either got it right, or they didn’t. Tonight you find out which.
This scenario plays out daily across mining and processing operations worldwide, and most organizations don’t know they’ve got it wrong until that phone call comes. They’re either sitting on millions in dusty inventory that’ll never be used, or they’re one failure away from catastrophe. The sweet spot in the middle is surprisingly hard to find. [Read more…]
