The gage measurements are expected to be stable, meaning the gage should provide consistent readings. Some random variation due to random error is expected. However, gage measurements change with time or because the gage is damaged. The gage stability can be checked by measuring a known reference.
In this article, it is shown how to use control charts to assess gage stability.
In the article Calculating Network Reliability the lack of published analytical solution for dual-ring network reliability was highlighted. This article provides a neat solution and further challenges readers to offer their proof or prior publication reference. The solution and the author’s general proof will be presented at RAMS 2020.
We offer three main services – projects, program management and training. This video illustrates the typical progression of service use through a case study. Don’t be afraid to skip ahead in the process! [Read more…]
60% of failures and safety issues can be prevented by ensuring there is a robust equipment design and that Maintenance & Reliability is taken into account during the design phase. Equipment should be designed with the following in mind:
ISO 31000 is the International Enterprise Risk Management (ERM) framework developed in 2009 by the International Organization for Standardization (ISO). Its use in government is increasing. The reason for the increase is that governments around the world are recognizing that risk events are increasing in frequency and cost. For instance, Hurricane Harvey impacted the States of Texas, Louisiana, Mississippi, Tennessee and Kentucky. It flooded 19 water systems, 31 waste water systems and 13 super fund sites spreading toxic waste throughout the region. It cost Texas $125 billion dollars. (1) [Read more…]
We discuss what traits make successful reliability journeys happen. This is part 2 of 2. (part 1 is here) [Read more…]
Who knew that the ocean could teach us something about Reliability Centered Maintenance (RCM). Join me on Daytona Beach and we’ll debunk one of the most common misconceptions about the process. [Read more…]
Evolutionary operations is an approach to design of experiments that is not commonly known. Where can it apply? May it be useful in your situation? [Read more…]
Let’s face it, the field of reliability engineering is diverse and full of statistics, models and detailed analysis. The detailed calculations, the building of models and analysis, have been performed with great success in the past and currently. The models built through manual calculation have been successful and demonstrated the importance of reliability engineering.
The rule is simple. For high-risk issues, the FMEA team needs to properly identify the cause(s) and associated failure mechanism(s). So, what exactly is a failure mechanism?

On December 29, 2018, RCM celebrated its 40th birthday. This process offers us two very important gifts. And they are just as important (if not more relevant!) today as they were in 1978. [Read more…]
Most senior managements don’t know that Reliability can get them high profits very quickly. And therefore high return on investment. Hyundai’s Ten Year Warranty. Their market share was going downhill for over ten years, suddenly it started to go upwards instead. All because of high reliability!
The impact of reliability extends far beyond reliability itself. It establishes the cost of warrants, repair, maintenance, logistics and the indirect costs of unavailability, downtime, and the COST OF SAFETY RECALLS which runs to hundreds of million dollars., and throughout the life of the product. This paper presents an outside-the-box view of how to get the best results by aiming at twice the life in the product specification and by preventing the high-risk failure modes resulting in an extraordinary return on investment, as much as 10,000%.

People are drawn to use of the blocking feature in Design of Experiments quite often. My experience shows that it is overused. This video explains my rationale. [Read more…]
“I told you so…” is so often cried after something has gone wrong. But was that ‘telling‘ stated clearly and unequivocally before things went wrong or was it merely a passing counterview against a probable likelihood based on an alternative possibility.
When a risk manifests itself and takes a grip on a project it’s amazing how quickly hindsight can kick in. This comes in the form of free advice as to what could have happened to avoid the risk ‘after the fact’. These latter-day soothsayers were, for some reason or other, unprepared to prove their prophetic ability before the fact preferring, it would seem, to go with the flow as an uninvolved observer but officious bystander when all facts are revealed.

Have you ever wondered how RCM principles emerged? They were born from a hard-fought lesson in the mid 1960s by the commercial airline industry. Watch as I explain from 25,000 feet! [Read more…]
