A Study of Product Development Engineering and Design Reliability Concerns

This article explores the evolution of product development engineering by providing an overview of the different developmental stages from a historical perspective. Furthermore, design reliability evaluation which is a key component of product development engineering processes is studied by reflecting and providing guidance on how to sort and assess reliability information early at the product design stage, as well as how to account for flexibility and expert's attitudinal character (information), which have been found critical in the assessment of engineering products reliability.
