DFSS Activities Four Principal Activities <br />Concept development, determining product functionality based upon customer requirements, technological capabilities, and economic realities <br />Design development, focusing on product and process performance issues necessary to fulfill the product and service requirements in manufacturing or delivery <br />Design optimization, seeking to minimize the impact of variation in production and use, creating a “robust” design <br />Design verification, ensuring that the capability of the production system meets the appropriate sigma level. <br />Like Six Sigma itself, most tools for DFSS have been around for some time; its uniqueness lies in the manner in which they are integrated into a formal methodology, driven by the Six Sigma philosophy, with clear business objectives in mind. <br /> <br />Tools for Concept Development <br />Concept development – the process of applying scientific, engineering, and business knowledge to produce a basic functional design that meets both customer needs and manufacturing or service delivery requirements. <br />Quality function deployment (QFD) <br />Concept engineering. <br /> <br />Key IdeaConcept Development <br />Developing a basic functional design involves translating customer requirements into measurable technical requirements and, subsequently, into detailed design specifications.
