Vital PWW EAM Core Science and Life Cycle Concepts

To get world class reliability needs a deep and solid understanding of why business systems, processes, and equipment failures occur, and the sure steps to follow to make your company world class reliable.

The foundational concepts that lead to operational excellence already exist, yet few organizations reach the heights of operational success.

Plant Wellness Way EAM is the result of over 20 years of industry experience and research into understanding why assets fail, and what are the truly effective core life cycle EAM concepts that ensure industrial plant and equipment get world class performance.

Below you can read about the core life cycle EAM concepts that PWW EAM uses to get the greatest operational successes for its users. Simply follow its methodology and use its techniques on your business. The new successes you get are firmly grounded on empirical and scientific evidence across the fields of engineering, finance, and group psychology. Put the core life cycle EAM concepts to work in your company and take the sure path to world class operating asset reliability.

Foundational Concepts

There are 5 core life cycle EAM concepts that contribute to improving equipment reliability and ultimately lead to reaching zero-failure operations. These 5 foundational concepts are the difference between developing business systems and maintenance strategies that produce average or outstanding operational performance.

Parts will fail when they are subject to forces or environmental factors that are beyond the limits of stress of their material.

Maintenance is an economic decision. Put another way, equipment failures cause huge profit losses.

Every system is perfectly designed for the results it gets. (W. E. Deming)

Systems are interrelated and are only as reliable as their individual parts.

Business processes are often a long series of steps. So, the success of each step is dependent on the success of the previous. i.e. Poor work quality multiplies across a process.

Operational Analysis Tools

Plant Wellness Way EAM methodology applies the wisdom of these 5 concepts through the IONICS process. Each stage of the IONICS process incorporates tools for operational analysis and risk analysis. When used properly, these tools provide valuable feedback on the business risks that exist, and how they can be removed from your operations.

Total Defect and Failure Cost Analysis (TDAF Costs)

As the name alludes too, a TDAF Cost Analysis calculates the true cost of failure to a company. A rough rule-of-thumb is that the TDAF Cost is around ten times the direct maintenance costs. The table below lists a summary of the various costs that should be considered as part of this analysis. By quantifying the true cost of each cause of failure, you can determine what steps for prevention and elimination are financially viable, and which risks are economically reasonable to take on.

Design and Operations Cost Totally Optimized Risk (DOCTOR)

The DOCTOR process is a comparative analysis tool that allows designers to design and select equipment that will bring the greatest improvements to the company. It explores the expected future costs of failures of assets by using TDAF Costing and life cycle modelling with Net Present Value (NPV) methods.

As a result, designs and equipment selections with high failure costs are identified before they are implemented allowing the most profitable business decisions to be made and built into the operation’s future success. When problems cannot be removed, strategies are chosen that reduce the likelihood of their occurrence and limit their consequences.

Stress to Process Model: the Greatest of the Core Life Cycle EAM Concepts

If we had to summarize the Plant Wellness Way EAM philosophy in a single model, the Stress to Process Model would be that. As done with the IONICS Process, the Stress to Process Model focuses on identifying the causes of atomic stress (also known as causes of failure or risks), and how they can be best prevented.

These actions are then used to guide the development of operational and maintenance strategies and processes. As a result, a new enterprise asset management system is developed, in which keeping equipment within their precision operating zones is consistently achieved, securing operational excellence.

Guarantee World Class Reliability Success for Yourself. Industrial and Manufacturing Wellness: The Complete Guide to Successful Enterprise Asset Management

Industrial and Manufacturing Wellness: The Complete Guide to Successful Enterprise Asset Management explains how to use system reliability engineering principles to design and build robust, reliable, and self-improving companies. This book explains how to develop and use integrated business systems to achieve optimal production performance and make operating fortunes.

Written by operating asset management expert Mike Sondalini, the book explains why and how Plant Wellness Way EAM methodology ensures engineering, operating, and business processes and workflows that get operational excellence.

Plant Wellness Way EAM is explained in Industrial and Manufacturing Wellness book

I have been focusing on RCM while at Toyota Motor Manufacturing NA. When I found Industrial Maintenance Wellness it bridged the gap between operational failures and component molecular failures. Mike’s process are excellent and the documents he has develop shows deep understanding of how components fail and how to prevent performance loss. I recommend it as part of a any library, for studies in reliability or team, as training tool it excels reducing the leaning curve.
