Faulty design can be especially costly both to the manufacturer or vendor and to the user.
Moreover, in an increasingly competitive global economy a product's edge may rest on the insight and effectiveness of its designers. The globalization of markets, the sophistication of technology and manufacture, and the complex of regulations set up by the nations of the world all add to the difficulties of doing good design. Rarely can a product be designed by one person in one place at one time. Modern design is collaborative and distributed over both space and time. This is not easy.
