In his book Reliability Centered Maintenance1, John Moubray highlights 6 patterns of failure. However, one needs to be careful about how those patterns are interpreted and used. Or misused. These 6 failure patterns are as follows:

The term MTBF (Mean Time Between Failures) within maintenance management, it is the most important KPI after Physical Availability. Unlike MTTF (Mean Time To Failure), which relates directly to available equipment time, MTBF also adds up the time spent inside a repair. That is, it starts its count from a certain failure and only stops its counter when this fault was remedied, started and repeated itself again. According to ISO 12849: 2013, this indicator can only be used for repairable equipment, and MTTF is the equivalent of non-repairable equipment. [Read more…]

Corporations that create in this world facilitate so many integral pieces to contemporary life by way of manufacturing. Manufacturing is quite literally a backbone to so many other industries, generating components for medical devices, automobiles, electronics, and machinery that keeps everything progressing forward. All of these components frequently need to be replaced, or more often upgraded thanks to new innovations that create new capabilities and in turn create new needs.
In addition, global supply chain shortages are driving a new wave of nearshoring to put manufacturing closer to customer locations. New manufacturing plants will utilize the latest technologies in an effort to increase productivity and competitive advantage. Due to the fact that technology-driven exponential change affects everything, manufacturing businesses must always keep up.

Dear friends, this is part-2 of our video on Design of Experiments using Minitab. In part-1, Hemant Urdhwareshe had explained how to create design using Minitab. In this part-2 of the video, Hemant has illustrated complete details of analysis of the design using Minitab. Analysis includes interpretation of Minitab output in voice and text!
We are sure, you will find this video extremely useful for Quality Practitioners, Reliability Engineers, Design and Process Engineers, Six Sigma Professionals, Design for Six Sigma practitioners. Some corrections at 5:21 — The R-sq value is 95.45, R-sq Adjusted is 92.53 and R-sq Predicted is 86.63%. There is some error in these figures in the video. Apologise for the oversight.

Reliability engineers, systems engineers, and other technically trained professionals often support big decisions. Big decisions involve high levels of complexity and uncertainty, Decision makers are driven to seek the advice of an inner circle. Team dynamics overpower individual preferences. The second S in the FINESSE fishbone diagram stands for Synergy. These three tips and a three-minute video will help you improve Synergy.

It seems a big misconception in different industries between those two terms “Reliability” and “Durability”. So, first thing first, I apply google research to find out what is definitions:
Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time or will operate in a defined environment without failure. (Source American Society for Quality (ASQ))
Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. (Source Wikipedia)

Reliability activities serve one purpose: to support better decision making.
That is all it does. Reliability work may reveal design weaknesses, which we can decide to address. Reliability work may estimate the longevity of a device, allowing decisions when compared to objectives for reliability.
Creating a report that no one reads is not the purpose of reliability. Running a test or analysis to simply ‘do reliability’ is not helpful to anyone. Anything with MTBF involved … well, you know how I feel about that. [Read more…]
The purpose of training your people is to develop capabilities the business needs and to add value to your people so they feel that they have greater worth. But the most important benefit of training is often lost because managers do not get their newly trained people to improve the system of work with their better knowledge and skills.
Everyone needs training to reach their highest potential. Training introduces new ideas and new ways that make us more effective people. There is one vital issue managers need to keep in mind about training if you want to get the greatest returns from the investment in time, money and commitment. Only training put to use returns value and only training of value is of use.

In any given PSM audit, the auditors will usually face one or more situations that represent a dilemma because the situation has not happened before, or no thought has been given on how to resolve it. These dilemmas usually require the individual auditor and/or the audit team leader resolve the situation in the field. These “on the fly” resolutions require both astute judgment and practical solutions that fit not only the governing regulations or company/facility standards for PSM, but also how those mandatory requirements should be interpreted and applied to the specific design, operations, and PSM program of the facility being audited.
The PSM audit dilemmas described in this paper are based on the experiences of seasoned auditors during actual PSM audits. Several of them are PSM adaptations of those published by Safety Projects International Inc., et al in 5 Star Health & Safety Management System™ Health and Safety Audits. In general, there are no absolute right or wrong answers to solving these dilemmas, although in some cases a resolution might seem obvious.

This informative video provides valuable insights into how we respond to operations and help them improve their processes. By pulling data out of the CMMS, we can identify areas of opportunity and provide recommendations for improvement.
For example, by analyzing the data, we can see where operators may need training, or where improvements can be made in the incoming raw material process. Our goal is to provide practical, actionable advice that can help you maximize your resources and achieve success in your manufacturing facility.
