Reliability Centered Maintenance (RCM) was developed in the airline industry to be used for developing maintenance programs for new aircraft. There’s no doubting it – originally RCM was intended for new designs and arguably where the results of failure could be catastrophic, specifically the loss of life and where costs of maintaining had grown ridiculously high. Aircraft maintenance costs had indeed grown very high by the 1960’s and 70’s before RCM came along. In fact, one of the big drivers behind RCM was cost reduction. It worked too – in both the aerospace and nuclear power industries! Safety and other benefits were there too, but they were not primary drivers. Then, as today, cost was the problem that got the attention. [Read more…]

Educational institutions realize that we all learn differently and combinations of learning styles will reach most of us. Some of us learn by seeing (reading), some by doing (tactile), some by hearing (aural). Most of us have a bit of each of these and rarely only one is enough. In college and university there is reading as well as assignment and lab work. We need both, so, how do we learn once we leave the academic world? [Read more…]

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. [Read more…]

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? [Read more…]

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. The parts market is so lucrative that there is an entire industry of aftermarket, non-OEM parts manufacturers with their own reverse engineering capabilities to sell parts at costs lower than the OEMs. If you’ve ever needed an OEM part in a hurry, the premiums are even higher and lead times can be longer than the aftermarket parts “pirates,” as they are sometimes called.

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…]

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? [Read more…]

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. Cost cutting, if not done intelligently, is an immediate measure that often ends up reducing capability and / or capacity and leaves the organization weaker than it was before. [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…]

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…]

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…]

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.

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…]

You’ve acquired and are now implementing a new CMMS / EAM (Computerized Maintenance Management System / Enterprise Asset Management) computer software program to help you manage maintenance. It may be a simple functional system that only looks after maintenance and likely Maintenance, Repair and Operating (MRO) spares, or it may be part of a much bigger enterprise system that handles many business functions. Regardless, one question almost always arises when converting from one to another system – what should we do about our old data? [Read more…]
