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.

When you do a Root Cause Failure Analysis or a 5- Why there are no promises that you will actually find the true root cause and fix your problem. Investigating the cause of a failure is fraught with traps, such as making wrong assumptions, insufficient evidence, misinterpreting the evidence, misunderstanding, personal bias and second-guessing. There are necessary issues you need to be aware of that affect the RCA and 5-Why methods, and there are some good practices that you can adopt to improve your chance of doing a successful analysis when applied to equipment failures.

I read your article that compares maintenance costs to RAV and am inquiring to see what is your definition of ‘maintenance cost’ when measuring replacement asset value? Are you strictly referring to labor costs, or is this the cost of labor, services and capital equipment purchases to repair, replace or upgrade an existing machine?
Dear Tom,
In the example, ‘maintenance costs’ meant the direct and overhead maintenance costs – labor, parts, subcontract services and allocated overheads (i.e. supervision, management, associated infrastructure, etc. proportioned to direct labor hours) – incurred during the ‘normal’ operation of the car (i.e. the car is driven by a well-trained, responsible driver at the wheel). If you have a store/warehouse for maintenance parts then you add the proportionate cost of keeping and running the store to support the maintenance effort as part of the total cost of maintenance.

Maintenance and reliability problems are not new. Our forefathers and ancestors understood the value of smart maintenance and high reliability. They learnt from experience and passed their knowledge down to us through parables, stories, and sayings. The timeless advice of our forbearers on successful maintenance and reliability is as applicable to us now as it has been to every generation since the dawn of civilisation.
