Design for Six Sigma (DFSS)
Design for Six Sigma (DFSS) is a methodology that can be used to develop new products or services or to improve existing ones. It was originally developed by Motorola in the early 1990s and has since been adopted by other companies, such as General Electric and Honeywell.
DFSS is based on the philosophy of quality known as Six Sigma, which aims to reduce defects in a process to less than 3.4 ppm (parts per million). While traditional Six Sigma focuses on improving existing processes, DFSS is focused on designing products or services that are “right” from the start. This means that DFSS can be used to develop new products or services or to improve existing ones.
What is Design for Six Sigma (DFSS)?
Design for Six Sigma (DFSS) is a methodology that uses the principles of Six Sigma to design products, processes, and services with safety, reliability, and competitiveness in mind. The key components of DFSS include customer feedback, quality function deployment, design for reliability and testability, failure modes and effects analysis, design of elements, and a project charter. The goal of DFSS is to create robust designs that meet or exceed customer expectations while reducing variations in the final product. Pilot testing, validation testing, customer evaluations, focus groups, and peer reviews are all common steps in DFSS projects. A scorecard can also be used to measure the success of a product from start to finish.
Design for Six Sigma (DFSS) focuses on conducting Critical Parameter management (CPM) and addresses 2 “voices” – Voice of the Customer and Voice of the Process – which must be understood to minimize redesign and design rework. This is done to identify the few variables that dominate the development of baseline performance, the optimization of robust performance, and the certification of capable performance.
