Reliability Centered Maintenance is an analytical process used in decision making about how best to manage equipment and system failures, and their consequences. Much of its output comprises maintenance tasks with assigned task frequencies. Those tasks will ultimately be managed in your Computerized Maintenance Management System (CMMS) or Enterprise Asset Management Systems (EAM). You don’t need software to perform RCM analysis, but it is helpful. Read more “Myth busting 29: You can integrate your EAM / CMMS with RCM”
Many of you may be surprised to learn that Reliability Centered Maintenance (RCM) was actually developed with cost cutting in mind! Aircraft maintenance costs were huge. For example the Douglas DC-8-32 aircraft (a four engine narrow body jet liner built from 1958 to 1967 that carried 150 passengers) required upwards of 4,000,000 man hours of maintenance work for only 20,000 hours of flying time!

Reliability Centered Maintenance (RCM) is method for determining the most appropriate failure and consequence management strategies. It deals with your physical assets in your current operating context. The first four questions in the RCM method, are defined in standard, SAE JA-1011, “Evaluation Criteria for Reliability Centered Maintenance (RCM) Processes.” They utilize the time proven engineering method, Failure Modes and Effects Analysis (FMEA).

Root Cause Failure Analysis (also called, Root Cause Analysis) is great for eliminating the causes of failures. It’s usually used where there are major production, cost, safety, or environmental consequences. But it only deals with failures that have already happened – it is usually triggered by the very consequences you would have been better off avoiding altogether.

Reliability Centered Maintenance has been around since the 1970’s and it has proven to achieve amazing results wherever it has been used properly. As a reliability method, it guides decision making based on available evidence about past, and expected future, failures. It makes sense that failure data be part of that evidence. But do you need a lot of data?
A common mis-perception about RCM is that it requires a lot of data. Read more “Myth busting 23: We need lots of failure data to do RCM”
In the late 90’s, the show “60 Minutes” did showed that an average economy car worth $15,000 new would cost about $95,000 if it was to be built from aftermarket parts, and adding in an allowance for your own labor, excluding the uni-body (which wasn’t for sale). It is more or less a given that manufacturer’s make more money on parts for their products than on the initial sale of the product. Read more “Myth busting 22: We can’t trust OEMs”
Many believe strongly in the value of warranties on new / refurbished equipment. They go to great lengths talking about how important it is to do the manufacturer’s recommended maintenance to maintain validity of the warranty. This is a continuation of the last blog article on having too many failures despite following manufacturer’s recommendations. Manufacturer’s usually recommend maintenance and spare parts for their products. In our last blog we can see that those recommendations are often flawed. So what about their warranty? Read more “Myth busting 21: Are manufacturer’s warranties worth it?”
Manufacturers always publish recommended maintenance for users of their products. There are a few myths about this maintenance – one is that it will result in reliable operation of the equipment. In some cases it does, but in most, it does not. Why?
The myth is that the manufacturers always know best how to maintain their designs. Think about that for a minute. How many manufacturers actually use and maintain what they sell? Read more “Myth Busting 20: We must follow manufacturer’s recommended maintenance”
These days everyone seems to be cutting spending. It’s entirely discretionary, so it’s easy to eliminate. But is that a smart move?
But today, times are tough. Trade wars, protectionism, and generally sluggish economies before those were a factor have all contributed to poor corporate performance. Shareholders want more. But can you really cut costs to become profitable? No – of course not, at least not in the long term. Read more “Myth busting 19: High performing organizations spend too much on training”
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 “Myth Busting 18: There are a lot of savings in maintenance cost reductions”
