Your Reliability Engineering Professional Development Site
Welcome to "Reliability Knowledge," a series dedicated to sharing insights and expertise on the critical role of reliability in product development, useful life, and wear-out life. The articles and videos are designed for engineers, product developers, and anyone interested in understanding how to create products that not only meet but exceed reliability expectations throughout their entire lifecycle.
Reliability in Product Development. Useful Life Reliability. Wear Out Life Reliability. Here you'll gain access to a wealth of knowledge that bridges the gap between theory and practice in reliability engineering.
The 8D (Eight Disciplines) method is a problem-solving methodology designed to find the root cause of a problem, devise a short-term fix, and implement a long-term solution to prevent recurring problems. It was first introduced in Ford’s 1987 Team-Oriented Problem Solving manual and has since become a widely used problem-solving method, also known as Global 8D. The 8D process consists of eight disciplines, each focusing on specific aspects of problem-solving

Statistical distribution – it has important role in general life and of course in engineering specifically. So, what is all about?
During morning commute either by bus or vehicle, you take some budget of time. From your daily routine experience, you with very high probability, can predict arrival time. You also know how much time it will take, in less ordinary cases, like slippery roads, or cars accident along you route.

A short introduction to accelerated life testing or ALT. It is a method used to enhance product reliability by subjecting prototypes to stress levels significantly higher than those encountered in actual use. The idea is to rapidly induce failures which is equivalent to speeding up time.

Anybody who did some hardware test in they life, eventually will face the question of sample size.
Probably it will be a tradeoff between the test duration and amount of samples to test.
So how much is enough? One, three, ten?
