A short video defining accelerated life testing or ALT.
An introduction to ALT or accelerated life testing. ALT is a method used to enhance product reliability by subjecting prototypes to stress levels significantly higher than those encountered in actual use. In short, it’s a way to accelerate time.

This is a question someone posted to Quora and the system prompted me to answer it, which I did.
This question is part of the general question around which software tools do you use for specific situations. First, my response to the question. [Read more…]
Successful Wind Turbine Reliability Strategy Requires Proactive Removal of the Causes of Failure
The reliability assessment of wind turbine models is critical when making investment in wind technology. Issues to address include: corrosion, metallurgy, structural integrity, reliability, pressure vessel construction, electrical circuits, communication networks, and more.
Develop a life cycle wind turbine reliability strategy that minimizes operationg costs by maximizing component reliability.

In the previous article we discussed Waterfall, WaterScrumFall, big-A Agile and business agility. Dissonance abounds among organizations struggling to transition their approaches to building solutions and maintaining their existing legacy infrastructures while remaking how they evolve themselves. In attempting to navigate this they often adopt approaches that are destined not to really get them where they need to be.

The executives of the Powertrain Organization (transmissions, chassis, engines) wanted a methodology where teams (design engineering, manufacturing engineering, and production) could work on recurring chronic problems. In 1986, the assignment was given to develop a manual and a subsequent course that would achieve a new approach to solving identified engineering design and manufacturing problems.

Its known HALT is an effective way to find the weaknesses in your product during the reliability improvement program. In doing so, we view HALT as a qualitative test only. We cannot define the reliability and lifetime of the product from its results. So, unfortunately, we cannot use HALT for purposes of Type Certification, confirm the lifetime of Critical Parts, predict the warranty and maintenance costs, which are required, for example, for aviation.
If we could combine the effectiveness of HALT (high acceleration of testing) with the benefits of quantitative testing, we would get a very powerful tool for the Reliability Demonstration and the Reliability Development of the new products.
OPERATIONAL EXCELLENCE IS A RESULT
Operational Excellence requires a business system-of-reliability. Reliability is the chance of success, so a company built as a ‘system-of-reliability’ maximizes its operating profits and production success. The three requirements needed to create a system-of-reliability for Operational Excellence are:
1. A defect eliminating work quality assurance system where your processes are robust and anti-fragile to disruption, and insure right-first-time results. Only if processes are built to go right every time; are anti-fragile to error; and proactively prevent causes of problems, can you reach Operational Excellence.
2. Business-wide process innovation focused on optimizing for the highest productivity, least cost, and right quality output. Then you install the next generation of solutions for ever better productivity.
3. Holistic, lifecycle physical asset management for stable, reliable operation with outstanding availability, highest utilization and most sustainable throughput.
You do three phases to reach Operational Excellence the Plant Wellness Way: Design your system-of-reliability – Teach your system-of-reliability – Build your system-of-reliability. First, design a business that can be the best. Second, teach your leaders how to do the right things, rightly. Third, apply and do the right behaviours for success.

In June 2022 the Office of the Auditor General of Ottawa Canada issued an audit report on the city’s Enterprise Risk Management (ERM) process. This piece looks at the audit results and what they say about the state of ERM in local government. It also looks at how the recommendations compare with an ERM study in New Zealand. Finally, it discusses the implications for ERM going forward.

Sometimes shifting your perspective
is more powerful than being smart.—Astro Teller
A common approach for “no failure” testing is the use of the well-known expression
$latex \displaystyle&s=2 (1) \quad 1-CL={{R}^{n}}$
where CL is a confidence level, R is a required reliability, n is a sample size. Its parent is a Binomial distribution with zero failures. This expression is like a poor girl: [Read more…]
