Your Reliability Engineering Professional Development Site
Computerized data gathering and information management systems are indispensable tools for business. Just remember the last power failure you experienced and you’ll understand. Technology continues to develop and become more complex. The array of available business applications is astounding and more are added daily.
Most of us wouldn’t argue that if you can measure it, you can improve it. Performance measures do indeed drive results, both good and bad. Knowing where you are now and what you want to achieve by some point in the future do help you to outline your path towards your objective. Once you know your path, you then need a way to make sure you are still on it. And once you’ve past way-points, you also need to know that what you’ve achieved so far, continues to be sustained.
Materials management for maintenance purposes is often a big mess. When I visit operations (doesn’t matter what industry) I often hear complaints from maintainers that they cannot get the parts they need, when they need them. Sometimes, their supply chain (warehouse, inventory, and purchasing management) are indeed a mess, but more often than not maintenance planning is also a mess, and there is usually (almost always) a lack of integration between planning and supply chain.
Like the human body, our plant and mobile equipment will break down if it’s not looked after. If we exercise and push ourselves harder, we gain strength. Unlike our biological bodies that can self-repair, our physical plants and mobile equipment do NOT strengthen if we overload them. Yes, they will tolerate some abuse but not for long. Machinery, unlike biological organisms, can not recover from damage on its own. It needs a bit of basic care. Basic care is all about taking care of our physical assets so they continue to do what we need them to do. Take care of their fluids (e.g.: oils, coolants), keep them from running hot (e.g.: clean heat transfer surfaces like cooling fins), and keep them free of contaminants that damage their insides (e.g.: keep moisture and dirt out). In the “Uptime Pyramid of Excellence,” the pinnacle is “Choosing Excellence”. That choice implies an active application of all of the model’s components. It’s a journey, not a destination.
There are two things you must do in a successful maintenance program: be good at doing your work, and only do the right work. Both are needed to deliver asset reliability – the cornerstone of sustainable, safe and quality production levels. In chasing reliability many turn to programs for defining the right work, yet many of those efforts will fail. Why? Poor or ineffective planning. The greatest benefits come from defining the right maintenance program using RCM and then implementing with quality work and on schedule.
Failure of reliability improvement programs can be from poor execution of RCM, but more often it is the result of something more basic. They are stuck in a culture of unreliability. [Read more…]
Reliability depends on the right maintenance being done the right way, and at the right times. At the core of making that happen is the work management process. It is a six step process that’s fairly simple, but often not followed very well. Without, workforce deployment becomes reactive to emergencies and maintenance costs are high. Work done in those reactive situations is anywhere from 1.5 to 3 times as expensive as work that is fully planned and executed on schedule. In some industries the cost of emergency work is even higher. [Read more…]
All organizations are made up of individuals. Invariably they reflect each other – the organization reflects the choices of its people, and vice versa. For any organization to thrive and achieve, so too must its people. Without them you’re dead. [Read more…]
Reliable operations are far less expensive to maintain and operate and they produce more consistently. Yet most industrial operations are far from achieving high reliability. Getting there will require effort and that effort goes well beyond the maintenance department alone. They will need to change from reactive, break it then fix it thinking and un-informed cost-cutting measures that undermine reliability. They will need leadership, not management. Leadership is all about making change and taking your organization in new directions. It will be disruptive, or it won’t be much of a change. Leaders are the ones who rock the boat, managers will keep it stable. In choosing excellence you’ll be choosing a path of constant change and improvement. Leadership is needed – it’s about strategy, effective execution, and it’s about your people – without whom you will accomplish very little. If you want excellence, it begins with leadership.

Entropy and economics, like entropy and maintenance, are related. In part 1 there is a simple 3 legged stool model: design, maintenance, and operations being its 3 legs. It can deliver high performance at low cost and risk – i.e.: high productivity. It is important to keep the legs balanced and indeed intact! Doing so requires a bit of investment. In thermodynamic terms, we need to put some energy into the system to keep the entropy from growing. That energy is an investment in maintenance and the payoff comes in the form of steady, predictable revenues with a high margin for profit. Those words should be music to accountants’ ears.

Entropy fundamentals for more Uptime can help us understand maintenance and reliability a little bit better. Reliability requires good execution of the right maintenance (energy), otherwise we will see reactive maintenance (entropy and chaos) increase. Engineers are familiar with the concept of “entropy” and the laws of thermodynamics. The second law of thermodynamics states that the total entropy of an isolated system always increases over time. It can remain constant in ideal cases where the system is at a steady-state or undergoing a reversible process. So what does that mean for us in the world of asset management and maintenance?

Asset Management in Public and Private Sectors have some similarities and some contrasts. Most of our clients are in the private sector but occasionally we do some public sector work so we see both sides. Often, we notice distinct differences in practices and in what motivates those practices. Both have strengths and weaknesses. Both can learn a lot from each other. [Read more…]
These days most of us are used to instant gratification – we want it now and we want it cheap! When it comes to information, entertainment, finding your way around, and communications we more or less have it all at our fingertips. It’s also available to us just about anywhere. We can even order and pay for coffee to pick up on our way from the commuter train to the office – no line ups for delays. We can book houses, rooms, hotels, airlines, vacations, and rental cars at the touch of our fingers with apps that show us the cheapest options. [Read more…]
Are we on the right track with the right train? Your job is to improve reliability and you have a plan. It focuses on bad-actors, having the right data, cleaning up some parts data that is known to be causing delays in work execution, a bit of training in reliability methods, and your adding engineers. You are certainly on the right track with your plan and the actions you will take should indeed make some improvement. But are you on the right track? [Read more…]
The original edition of Uptime had “process re-engineering” as a 4th level at its pinnacle. It reflected what was then widely regarded as an approach to obtain beneficial change quickly. But, since the 1990’s that approach, was abused and used as a smoke-screen for downsizing or right-sizing as many would prefer to call it. That was never intended by the originators of “Business Process Re-engineering”, but it is what happened. It was lopped off the top of the pyramid in the 2nd edition – process re-design belongs as a result of strategy, not as a panacea for poorly designed and executed process. Processes should be revisited BEFORE implementation of IT / IM and occasionally it should all be reviewed as part of good governance, just like audits. The fundamental processes of good maintenance management practice are already described in this book’s chapters – how they appear on flow charts or value stream maps is up to each user. The third tier in Uptime (1st edition) was about Continuous Improvement, but it contained methods that were both more fundamental in their importance and more sophisticated than the tweaking that “continuous improvement” implies.

In the first edition, the second tier of the pyramid was called “control”. Of course the harder we try to control something, the more complex we make things, and the more likely they will go awry. If you have teenage children you can see that very clearly! You want them to learn and mature, but if you try to control how they do it, you will have trouble. Less control, while providing guidelines and advice, and letting them make their choices will work far better. In “Uptime” the emphasis is on successful practice, not control. Control is exercised in how you decide to implement the practices. The practices remain “essential” to your success no matter how you deploy them. The subjects covered in this level of the pyramid have remained much the same throughout all three editions of Uptime but they’ve grown richer in detail, providing more insight, and with emphasis on how tightly integrated they really need to be with each other.
