The Robust Design method has helped reduce the development time and cost by a factor of two or better in many such problems.
In general, engineering decisions involved in product/system development can be classified into two categories:
Error-free implementation of the past collective knowledge and experience
Generation of new design information, often for improving product quality/reliability, performance, and cost.
While CAD/CAE tools are effective for implementing past knowledge, Robust Design method greatly improves productivity in generation of new knowledge by acting as an amplifier of engineering skills. With Robust Design, a company can rapidly achieve the full technological potential of their design ideas and achieve higher profits.
