In this video, viewers will understand the basic concepts of Product Life Cycle. Phases of Product Life Cycle are Early Life period, Burn-in period or Infant Mortality period, Constant Hazard Rate Period and Wear-out period. Viewers will also get some understanding of the causes of failures in these phases.

An operating asset, such as a refinery or oil and gas platform, poses risks to people and environment.
A quantitative risk analysis (QRA) quantifies operating risks.
Let’s get the math out of the way!
For quantification, risk is defined as product of frequency and severity. [Read more…]
Let’s say that you and your team have done well. Your products or systems are reliable. They work, customers are happy, and the cost of unreliability is low. That’s the goal, right? Congratulations are in order.
However, enjoying great reliability performance was the goal. It is what we expected. It’s what we worked to achieve. Now what?

When Weibull analysis is applied to complex, repairable systems – like mining equipment – care must be taken to ensure the analysis is applied to failure data exhibiting a common failure mode on the component-level, not the system-level.
This requires the reliability engineer to review the work order data at times and, ideally, the failed components themselves. Otherwise, the “Garbage In, Garbage Out” principle applies.

Since I published my first contribution about reliability, I’ve received a number of emails asking where the stress and strength distributions come from (Figure 1).

The mental model CATER will help you recall the five techniques that improve collaboration and team dynamics. CATER does two big things necessary for all greatly facilitated sessions. The mental model creates comparable knowledge among participants and opens feedback channels for successful collaboration.
CATER is a mental model that identifies the core components of a system and helps you wrap your head around how the components interact. [Read more…]
This article is the tenth of fourteen parts to our risk management series. The series will be taking a look at the risk management guidelines under the ISO 31000 Standard to help you better understand them and how they relate to your own risk management activities. In doing so, we’ll be walking through the core aspects of the Standard and giving you practical guidance on how to implement it.

AFRs are periodic ratios of failure counts divided by installed base. Have you seen meeting rooms wallpapered with AFR charts (Annualized Failure Rate)? Have you sat through debates about the wiggles in AFR charts? Fred Schenkelberg wondered if reliability could be estimated from AFRs and their input data? How about age-specific reliability and actuarial failure rate functions? Actuarial forecasts? MTBFs? Wonder no more!

UNLIKE LEAN AND SIX SIGMA, THE PLANT WELLNESS WAY DIFFERENCE IS IT PREVENTS OPERATING RISKS FROM STARTING WITH A SYSTEM THAT IS BUSINESS-WIDE AND GOES END-TO-END OF THE WHOLE ASSET LIFE CYCLE
—
Lean and Six Sigma are point-in-time problem focused methodologies, where as PWW EAM System-of-Reliability uses the whole life cycle to build business and operational systems with processes that continually optimize productivity, minimize risk, and generate maximum operating profits.

Pascagoula gas plant receives condensate from offshore Gulf of Mexico.
For separating components at cryogenic temperatures, it used brazed aluminum heat exchangers. These exchanger are susceptible to thermal fatigue due to low temperaures.
What does it mean to be a ‘visionary leader’? It starts with being different to most people. You can’t just become a visionary leader by completing a leadership course, being mentored by someone awesome, or by compiling an impressive curriculum vitae (although these can help people with the potential to become visionary leaders get there).
One of the first things that the then United States Army Chief of Staff (General George C. Marshall) did at the outbreak of World War II was to fire the majority of his officers who had climbed the ladder of military ranks throughout the previous 20 years of relative peace.
Things get a little dirty when humans get involved. In any system, human involvement can sometimes cause delays or issues. Here are some effective communication and facilitation secrets for reliability engineers.
Communication is the exchange of information from one person to another.
Communication requires a sender, a receiver, and a message. Technical professionals (sender) usually believe the decision maker (receiver) cannot understand the message because the decision maker is not as smart as they are. Most of the time, the lack of understanding comes from the noise the sender generates. The burden of effective communication is on the send (technical professional), not the receiver (decision maker).

Fear is that hidden factor present in every organization, preventing leadership from achieving the growth they desire.  In the 2 previous articles, I brought up the types of employee fears and how that fear can negatively impact a given organization.  Additionally, I brought up the importance of assessing these fears and understanding how they’re specifically affecting your organization.  In this third and final article in this series, I’ll explore what leadership can do to mitigate these fears towards cultivating a culture of trust and empowerment.
