How do you work-out the right life-cycle maintenance strategies? Does one strategy apply throughout an asset’s life? What influences the choices and decisions as to what maintenance to do and when it should be done? How much money and resources do you expend in the maintenance of an asset? To keep the concepts behind these important questions on maintenance strategy selection simple they are applied to a sheet of paper.

Accuracy Controlled Standard Operating Procedures Use The 3T’s – Target, Tolerance, Test – For Work Quality Assurance
Assure production and maintenance work quality with accuracy controlled standard operating procedures containing 3t precision work instructions where work is done right-first-time, every time
—
An Accuracy Controlled Enterprise (ACE) is focused on getting things ‘right first time’. The quality focus in an ACE is about doing a job, every job, masterly, whether done on the shop floor or in the boardroom. That is achieved with accuracy controlled standard operating procedures in which every task is proven to be completed accurately before continuing to the next task. It is about being a master of what you do so you deliver world-class results in your work. You can read about being an ACE in the white paper The Accuracy Controlled Enterprise.

If you want to drastically reduce maintenance costs, stop lost production, eradicate unplanned outages and equipment breakdowns, you need to stop the continual introduction of defects and errors into your operation.
You do that by using quality management practices to drive continuous improvement of your management systems and so continuously improve the business processes, and your peoples’ knowledge.
To reduce maintenance costs and production downtime it is necessary to reduce the causes of the maintenance and downtime. Both maintenance and downtime are an effect and not a cause. The causes can be traced back to defects and errors from a variety of sources. Knowing that defects eventually lead to future equipment failures, production downtime and lost profits, it is necessary put strategies into place to purposely prevent them occurring in the first place and to eliminate them if they are present.

The article was written to cause people to question traditional approaches to FRACAS. In time senior managers in companies will come to realise that FRACAS has little chance of successfully improving their company. They then can instead look for what does work to move their operations to world class production performance.

A RELIABILITY IMPROVEMENT POLICY IS A DOCUMENT CONTAINING A SET OF PRINCIPLES TO GUIDE DECISION MAKING AND ACTIONS. IT TELLS HOW RELIABILITY WILL BE ACHIEVED IN AN OPERATION. IT COVERS THE WHOLE ASSET LIFE CYCLE AND SAYS WHAT WILL BE DONE AT EACH PHASE TO DELIVER RELIABILITY.

Unfortunately, we have been operating in a crisis manner without a reliability improvement policy. Have you samples of a Reliability Improvement Policy that I can use as a basis of crafting one for my organization — do you have anything to share?
As I have stated in the past, the materials you post have been a big blessing to my work. You have definitely empowered me with great information that I see changing the way people work.
Hello Friend,
Industries using machines require them to run reliably (no failures or unplanned stoppages) with high availability (ready for immediate use) and high utilization (continuously in use) all their working life.

High equipment reliability is a choice and not an accident of fortune. To a great extent you can choose how long you want between equipment failures. You can deliver high equipment reliability by ensuring the chance of incidents that cause failures of equipment parts are low. The secret to remarkably long and trouble-free equipment lives is to keep parts and components at low stress, within good local environmental conditions, so there is little risk they are unable to handle their design duty. If there is nothing to cause a failure, the failure will not happen and your equipment continues in service at full capacity and full availability.
For maintenance practitioners, it is the use of precision maintenance backed-up with condition monitoring applied as a tool to prove maintenance work is done precisely, that provides the foundation for exceptional equipment reliability.

Improved reliability has a cause. Just like a failure has a cause, so too is there a cause for improved reliability. You can wait for a failure to happen and then learn from the experience and change your processes to prevent it. That is root cause failure analysis. But it is not proactive behaviour. Such an approach quickly buries you in firefighting. It helps you fix a few terrible failures, but not the tens of thousands of defects that are waiting to create the next lot of disasters. Permanent reliability growth requires proactive methodologies that identify all potential problems and stops them from starting. This is what is done in high reliability operations – they never allow defects to begin.
The process maps of your business processes, the workflow diagrams of your operating procedures and the bills of materials for your equipment are the foundation documents for improving equipment reliability. They are used respectively to control the business processes, to control human error and to address limitations in materials of construction and parts’ health practices.

Find the fortune maintenance can make for your business. Unfortunately, maintenance people get praise when they repair breakdowns. This embeds and promotes a culture of equipment failure acceptance in a business. Maintenance must be used to prevent equipment failures, not fix them. If you want to start a culture of failure elimination in your business you have to start putting a money value on the breakdowns prevented by Maintenance. You have to start praising and recognising them for the breakdowns they didn’t let happen. Maintenance needs to be praised and glorified for the money it makes a company, not singled out for the money it spends.

Reliable equipment is necessary to reduce production costs and maximise production throughput. High reliability from operating equipment requires high quality reassembly, coupled with the correct operating practices. You can guarantee correct maintenance and proper plant operation by specifying a target and tolerance in maintenance and operating procedures.
Having a target and tolerance sets the recognised acceptance criterion. A simple proof-test will confirm if it has been met. Specifying a mark and tolerance range changes the focus from one of simply doing the job; to now doing the job accurately. This results in high quality trades’ workmanship and sound equipment operator practices that deliver reliable equipment performance. Those organisations that use ‘target, tolerance, proof-test’ methodology in their procedural tasks move from being a quality-conscious operation to being an Accuracy-Controlled Enterprise (ACE).

Welcome to the start of the training users get on how to build a Plant Wellness Way enterprise asset life cycle management system-of-reliability once their company begins using the PWWEAM methodology.
Throughout the course we interchange the name of the methodology commonly called ‘Enterprise Asset Management’ with engineering asset management, physical asset management, and asset life-cycle management. All these names mean the same thing. We also will switch between referring to Plant Wellness Way Enterprise Asset Management methodology to shorter versions, such as PWW EAM or PWW.
Many companies adopt root cause failure analysis (RCFA) and then drop it. They use it for while and get no benefit. RCFA is often ineffective when used to solve individual problems. But when used to find systematic causes of problems and improve business systems, it provides grand payback for the effort.
Keywords: root cause failure analysis, business process improvement

Much of what we do in engineering and maintenance we accept without question. People say, ―It‘s been done that way for decades,‖ implying that it must be correct. But for equally as many decades have come stories of failed and broken machinery, plant and businesses. On one hand we continue to unquestioningly do what has been done for generations, yet on the other hand we cannot stop equipment failing. There is a subtle connection between the two of which we are only just becoming aware. The connection is obvious when you realise that we have been running our businesses by risk and luck, and not on facts and understanding.
