What is Design for X (DfX)?

In this episode, Ricardo explains a very important concept on product design called Design for X (DfX). Fundamentally, design can be driven by several different objectives and by giving priority to one element (X) we can simplify, improve control and refine the product development process. Largely used in engineering and product development, the term "X" can mean different aspects of the product like Cost, Safety, Disposal, Usability, Manufacturing, among several others.
