Functions is the first step in the RCM process and they serve as the foundation of the RCM process. Properly written Functions serve two very important aspects of asset management. [Read more…]

When you think about maintenance from a reliability perspective rather than an engineering perspective, it becomes clear that transformers are somewhat of a red-headed stepchild, even though they are the heart of the electrical system.
Why? Let’s take a closer look.

This case history takes place in a packaging facility in Virginia. The packer on module E5 was checked for vibration integrity during a pre-machine care evaluation. A problem was detected in the folding arm gearbox. The frequency characteristics indicated a bearing was deteriorating.
This seems very straight forward but let’s put the reality of the situation into the problem detected. The gearbox is located in a section of the packer that is not easily accessible. To do the necessary repairs it will require separating the two sections of the machine. When the packer is split it will take an additional two days of work before the unit can be restored to service. [Read more…]
This one is a HUGE MYTH. Maintenance costs are a direct result of what you do and what you do produces capacity for service delivery or production (depending on your business). Cost is a consequence of your actions, available cash (in a budget) does NOT determine what you will spend. [Read more…]
It’s another Saturday at my house. In this video we use RCM principles to determine if the replacement task my husband is performing on his 1989 Toyota Supra is both technically appropriate and worth doing. [Read more…]

At the root of most mechanical and system failures lurks a human cause. Insights into what to look for when solving human-caused failures are essential. Human error is generally described as behavior that goes beyond the norm. A proper definition in the context of this article is, “an action planned but not carried out according to the plan”. To find a means of minimizing human error, one must first understand its characteristics: [Read more…]
The last article speaks to who should run your storeroom – NOT maintenance. It also leaves us hanging a bit – what should go into the store room to ensure good supply of needed materials, when needed? [Read more…]
My mentor John Moubray taught me that managing the consequences of failure is the essence of RCM. Watch how I used RCM principles to change the consequences of failure with a Default Strategy. [Read more…]

As VP of reliability at my company, I often meet customers when they are at the tyranny of the urgent. They’ll have a significant problem, multiple questions, and a big decision to make.
Just recently I was with one of our customers as he was facing one of those big decisions. It was a tough one. [Read more…]
In order to know if all RCA is the same, we first have to define ‘What is RCA?’ On the surface this seems quite simple, but unfortunately it is quite complex. When I train or present speeches around the world, I often poll my audiences about how they define ‘RCA’. The fact is I will get as many answers, as I have people that I ask. This is unfortunate because there is no universally accepted definition of what ‘RCA’ actually is. Are there definitions out there, absolutely! There are hundreds of them. Various regulatory agencies have their own such definitions, as do corporations and companies. However, when definitions differ between agencies, corporations and industries, it is hard to measure the effectiveness of ‘RCA’ across the board, because everyone considers whatever they are doing, as ‘RCA’.
Perhaps the number one excuse that maintainers use for being unable to get repairs executed in a timely manner is to blame parts and their supply. For the maintenance technician on the tools, it’s a very obvious problem. No parts or materials means that work simply cannot be done without some sort of work-around / jury-rigged solution. The alternative is to get the needed materials as quickly as possible – often incurring substantial premiums on the price of the materials and premium shipping charges. When the parts arrive, usually after some waiting period, all emphasis is on getting the job completed even if it requires overtime effort and costs. This makes compliance to budget a real challenge and invites plenty of queries from accounting, finance and general management about our ability to work within a budget. As fire fighters we are sometimes heroes, but as managers we are failures. [Read more…]
No matter where we work, we will experience failures or ‘undesirable outcomes’ of some kind. As long as we work with other humans, this will indeed be the case. These failures may surface in the form of production delays, injuries, customer complaints, missed deadlines, lost profits, legal claims and the like.
In order to prevent recurrence of any such undesirable outcome, we have to truly understand the causes that led up to that bad outcome. In many of our worlds, the process used to analyze and understand what went wrong is called Root Cause Analysis or RCA. However, for the sake of this article, call this process whatever you want; problem solving, brainstorming, troubleshooting, etc. The common denominator of these terms, is they desire to resolve a failure and ensure it does not happen again.
Let’s get away from labels and specific industries and focus on the anatomy of a ‘failure’. Where does a failure come from? Think about this no matter where you work and see if it applies. [Read more…]
Many believe that if you can’t measure it, you can’t manage it. That’s just not right. Measurements can only count what is countable – dollars, production numbers, headcounts, timeliness, etc. They can’t count the achievement of objectives unless those objectives are purely numeric in nature.

A few weeks ago I went to a customer site where they had a meeting of the minds for their reliability team. The host was a multi-site paper manufacturer with an intelligent approach to plant reliability. The reliability team included, of course, several reliability professionals, but there were procurement people there too. That’s not unusual. We’re finding more and more that procurement and reliability often work hand in hand. [Read more…]
In theory, integrated computer systems enable multiple uses for any single piece of data that is input only once. Data becomes available wherever it needs to be in whatever business process is integrated into the whole. In a sense it is like our brains – information and experience is registered once and available for access whenever needed for any purpose. Integrated systems should make our lives at work easier, but they seldom do that. Integrated business computer systems are very complex and can be very difficult to use. Imagine that they must support many separate business processes and departments, all of whom have different “languages” and ways of doing things. [Read more…]
