• Resumen

  • One of the most tangible contributions to quality engineering over the last 15 years is the concept of robust design and its concrete realization by means of designed experiments. However, robust design as promoted by the Taguchi method clashes with design theory as it puts emphasis on parameter design as the most important means of robustifying technical systems. It is argued in this article that the design phases that precede parameter design ∥i.e. system design) actually determine the attainable level of product robustness in the parameter design stage. It is shown how qualitative methods in the form of design principles can be utilized in early design phases to support the process of robust design.
