Product or process designs have three phases:
Systems (part) or concept design. This phase arrives at the design architecture (size, shape, materials, number of parts, and the like) by looking at the best available technology. Gate reviews focus on design and performance against customer and functional requirements.
Parameter (or robust) design. This stage focuses on making the product performance (or process output) insensitive to variation by moving toward the best target values of quality characteristics.
Tolerance design. This stage focuses on setting tight tolerances to reduce variation in performance. Because it is the phase most responsible for adding costs, it is essential to reduce the need for setting tight tolerances by successfully producing robust products and processes in the parameter design phase.
