Describe the principal activities in the Design for Six Sigma process.

DFSS consists of four principal activities:

1) Concept development, in which product functionality is determined based upon

customer requirements, technological capabilities, and economic realities.

2) Design development, which focuses on product and process performance issues

necessary to fulfill the product and service requirements in manufacturing or

delivery.

3) Design optimization, which seeks to minimize the impact of variation in

production and use, creating a robust design.

4) Design verification, which ensures that the capability of the production system

meets the appropriate level of performance.
