These first four steps will be conducted using a technique called Quality Function Deployment (QFD), a tool commonly used in the Design for Six Sigma (DFSS) approach. See the Design Process (Chapter 5) handout for details.In ES305, we will use elements of the Design for Six Sigma (DFSS) approach, e.g., Quality Function Deployment (QFD). See the final page of this handout for a more detailed description of DFSS. The Design Process (Chapter 5) handout will provide a detailed description of how to apply QFD to develop a Product Design Specification (PDS) and drive the Conceptual Design process based on DFSS principles.The Design for Six Sigma Approach: Design for Six Sigma (DFSS) is an emerging concurrent engineering design approach for product development that focuses on the creation of new value based on inputs from customers, suppliers and business needs. DFSS seeks to avoid manufacturing/service process problems by using Voice of the Customer (VoC) techniques and appropriate systems engineering techniques to avoid process problems at the outset. DFSS practitioners use system simulations and parametric system design/analysis tools to predict both cost and performance of candidate design solutions. When combined, these methods obtain the proper needs of the customer, and derive engineering system parameter requirements that increase product and service effectiveness in the eyes of the customer. This yields products and services that provide greater customer satisfaction and increased market share. DFSS techniques include tools and processes to predict, model and simulate the entire product delivery system (the processes/tools, personnel and organization, training, facilities, and logistics to produce the product/service) as well as the analysis of the developing system life cycle itself to ensure customer satisfaction with the proposed system design solution. DFSS makes use of many tools, such as Quality Function Deployment (QFD) and Design of Experiments (DOE). In this class, we will focus on use of QFD to develop a Product Design Specification (PDS) that will drive the Conceptual Design process based on DFSS
