Normal distribution is most common in real life scenarios be it modeling any reliability performance parameter at a specific time. Central Limit Theorem (CLT) shows why normal distribution occurs so often.

As the world begins to unevenly emerge from the COVID-19 pandemic, people’s re-evaluation of their lives and work means employee engagement has been replaced by employee experience.
Employee experience is about the critical need for organisations to help people do and be their best. It is shaped by:
Even before the pandemic, the work environment was already challenging. Many studies have shown that people felt overwhelmed. They had little time to concentrate, to spend with their families, and there was no time to learn something new.

This white paper will teach you how to solve your plant and equipment reliability problems and improve your current plant and equipment reliability up to magnificent performance.
Since the mid-1980’s we have known exactly how to guarantee incredible equipment reliability. Failure-free machinery and equipment is totally achievable (in fact it is remarkably straightforward to do). We have all the answer—we know all the science; we know all the engineering; all the necessary information is readily available. The research has long been completed. The correct solutions for magnificent reliability are practical and quite doable. The problem that remains, is that though we know exactly what needs to be done to get magnificently reliable machines, we cannot get companies to do it right. The limitation to achieving magnificent reliability is not technical. The limitation now seems to be organisational, cultural, and human factors related.

Dear viewers, I am happy to release this third video on Accelerated Life Testing. In this video of part-3, we have explained how to use Minitab software to analyse data of accelerated life test. The illustration uses Arrhenius Model, but the technique can be applied to other models as well.
The video will be useful to all those who want to learn and apply technique of Accelerated Life Testing. It would be of help to those who wish to take ASQ CRE certification exam. It would also be useful to DFSS practitioners.

When it comes to managing risk, there are three elements to consider and RCM can help you define all three. Watch as I manage risk and change consequences all at once!
Reliability engineers and other technical professionals are challenged when communicating their work to senior management. The FINESSE fishbone diagram provides a system-thinking, cause-and-effect approach for communicating in the face of complexity and uncertainty. The first S in the FINESSE fishbone diagram stands for Structure. These three tips and a three-minute video will help you improve the structure of your presentations and reports.

This video is for all the GE APM users who want to get the most from the APM investment. Queries are a critical part of the GE APM solution and mastering query building will help you get the most out of the solution. This video will focus on a great query function that allows users to use if-then logic in their queries.

When I was a bright eyed, motivated (younger) officer in the Australian Army, one my many tasks when deployed overseas was to raise paperwork to formally request ‘battlefield material’ to be sent back home from whatever country we were in. ‘Battlefield material’ was items that included a range of mementos, keepsakes, and things you would typically see in a museum to add to the historical collections of my battalions and regiments back home.
The following note and question appear in my email the other day. I had given the definition of reliability quite a bit of thought, yet have not really thought too much about a definition of ‘product life time’.
So after answering Najib’s question I thought it may make a good conversation starter here. Give it a quite read, and add how you would answer the questions Najib poses. [Read more…]
Ernst Hjalmar Waloddi Weibull (18 June 1887 – 12 October 1979) was a Swedish engineer, scientist, and mathematician. (source Wikipedia)
In days of yore, systems development projects were front ended with laborious requirements engineering and design tasks. This made sense then because development was labor-intensive, time-consuming and expensive. Changes to the scope or design of a solution mid-development increased the likelihood of errors and incremental time and expense. In recognition of this, traditional Waterfall project management was applied, which created impediments to modifying the product definition once its development had begun. Changes were strenuously resisted.

When you run machines above design rates that decision goes against all that we know about creating high plant uptime and outstanding equipment reliability—in fatigue situations 10% additional stress will cost you ten breakdowns.
The dominate factor in machine life and production plant uptime is the stress in your machines’ working parts. The stress developed in a part’s material of construction microstructure is directly linked to the force applied to it. It does not matter where the force comes from or why it is applied, once the stress in your parts go beyond their microstructure limits your machines fail. If you want to run at high production rates first ensure that your working parts cannot become overstressed.

Dear viewers, I am happy to release this second video on Accelerated Life Testing. In this video, we have discussed (i) Various models used to estimate the acceleration factor, such Arrhenius, Power law etc. (ii) Application examples showing calculation of acceleration factor (iii) Some mathematical relationships to estimate reliability at normal operating conditions and illustrated examples (iv) Types of stress loading used in ALT.
The video will be useful to all those who want to learn ALT and its mathematical relationships. It would be of great help to those who wish to take ASQ CRE certification exam. It would also be useful to DFSS practitioners.

We are back with our 4th installment in the Opportunities for Maintenance and Operations series! We have discussed alarms, rework, and event rates. Today we talk about PM Routes. What can a PM Route do if our CMMS system has the ability to manage them? How does one take advantage? Watch the video and find out.

Leaders and managers play many roles: planning, scheduling, coaching, teaching, supervising, hiring, and sometimes firing. While much of this work is routine, it often involves making decisions. Some decisions are low-risk with clear facts and limited options. Others are made with murky details, unknown options, and high risks if incorrect. Regardless, decision-making often falls to leaders and managers. Theodore Roosevelt, the 26th President of the United States, famously said: “In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing.”
