Understanding Product Reliability and Failure Analysis — Lesson 1

This lesson covers the concept of product reliability and failure analysis. It delves into the importance of reliability in product design and how it is closely related to failure analysis. The lesson explains how reliability is a measure of a product's ability to perform its intended function over a specific period of time under certain operating conditions. It also discusses the factors that influence reliability, including design, production, and transportation. For instance, a product with a simple design and fewer components is likely to have higher reliability. The lesson further explains how to calculate reliability for systems where components are arranged in series or parallel.
