Asset Prioritization and criticality are used to provide a structured approach to determining the relative organizational risks and failure consequences associated with assets. This provides a means for the organization to focus on critical risks to the business.
Asset Management is more than maintenance and reliability, yet many often think they are the same. Asset Management is far broader and considers the entire life cycle.
How does your organization differentiate between asset management, and maintenance and reliability?
Early in the discussions around asset management, some organizations simply renamed their Maintenance and Reliability departments to Asset Management departments, even though they continued to do the same tasks and activities they always did.
Do you really need an assessment? Will it help, or will it create problems?
Conventional consulting approaches begin with detailed assessments to determine your current state of affairs, judge what’s good and bad about it, give it a score, provide a long list of recommendations and then build an improvement strategy based on the outcome. A typical assessment can take up to a couple of weeks plus report generation time. Does it really add the value you might expect?
Entropy and maintenance are more related than you might think. What happens in maintenance and many operations can be explained with this simple thermodynamic concept. Entropy is a concept that represents chaos and degradation. It occurs naturally in any physical system and will naturally grow (i.e.: the system will become more chaotic) if we don’t do something to arrest its growth. Doing something requires the expenditure of energy, so energy is what counters entropy. Entropy and maintenance are seldom discussed together, we don’t speak of these thermodynamic terms and concepts in everyday language and conversation, but they are at work behind the scenes. For practical purposes, if we want something to remain orderly we need to put some form of energy (effort) into keeping it that way. If we don’t, then nature will steadily and relentlessly increase the state of chaos in which we exist. In maintenance that means moving from proactive (which requires energy) to reactive (which drains it away).
Business processes are often talked about, yet not well understood. The big problem with them is that too few people know what the whole process actually should be. Whenever you are following a set of steps to achieve some goal you are following a process. Sometimes various people follow different steps to achieve the same goal. You rely on processes in order to deliver results. If they are ill-conceived or inefficient, then things move slowly and results are more expensive to obtain than they need to be. Well designed, efficient, and consistent processes that integrate with other related business processes keep things running smoothly, costs down, and help to keep people motivated.
Maintenance and Reliability improvement are keys to Operational Excellence – without them, you’ll suffer high costs and reduced outputs. This interview by Ryan Chan of UpKeep gives insight into what Uptime is, how it works towards Maintenance and Reliability improvement. The value it can deliver is high, how it does it is straight-forward, and leaders are needed to make it happen.
Emerging stronger from crisis – that’s our current challenge. We know we can do it. What doesn’t kill us makes us stronger. Our businesses can emerge stronger too, but that won’t happen without leadership and choice.
Capital asset-intensive industries that have had a chance to pause have been wise if they used the opportunity to catch up on deferred maintenance and review their proactive maintenance programs for effectiveness. They will emerge stronger. Better maintained equipment will run better, longer, and last longer, producing more and doing so with lower levels of risk.
There’s an old saying that, “two heads are better than one”. Teamwork has been proven time and again to produce superior results. It is the basis for many successful methods like RCM-R, PMR/O, RCFA, Total Productive Maintenance (TPM) and various quality improvement programs like Six Sigma. The various methods that help us while Choosing Excellence depend on a foundation of teamwork. Beyond facilitated teamwork, self-organized teams are even more effective.
You can wait for something to break, then fix it, or you can be proactive and manage the failure before it causes you problems. Being proactive is all about managing failures and their consequences before they occur. The failure itself, in some cases, is unavoidable, but how you manage consequences is entirely within your control.
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…]
