Design for Six Sigma (DFSS)

Designing Quality Into Products and Services

Design for Six Sigma (DFSS) is an emerging process management methodology related to traditional Six Sigma. While Six Sigma methodology targets breakthrough improvement of an existing manufacturing or service process (as part of a bigger picture of continuous process improvement), DFSS seeks to avoid manufacturing/service defects at the outset by improving the design process during the initial system/product development phase.

In short, DFSS aims to build the efficiencies of Six Sigma methodology into the design process before the implementation phase. The desired outcome of DFSS is a system/product solution that increases product and service effectiveness in the eyes of the customer, leading to greater customer satisfaction and market share.

To achieve this objective, DFSS uses advanced Voice of the Customer (VOC) techniques to determine the true needs of customers and the business, and driving those needs into the system/product solutioning process through effective systems engineering techniques. These systems engineering techniques include specialized tools and processes to model, simulate and predict system/product performances before implementation.

Included in the standard DFSS toolkit are methods such as Quality Function Deployment (QFD), Kano Analysis, TRIZ, Design for Assembly & Manufacturability, Robust Design of Experiments, Statistical Tolerancing, Sensitivity Analysis, Multi-Optimization and Reliability Engineering.

Similar to the DMAIC (Define, Measure, Analyze, Improve & Control) roadmap of Six Sigma, DFSS integrates the tools application systematically into an IDOV (Identify, Design, Optimize & Validate) roadmap, essentially deploying the best practices in VOC & systems engineering into the design process.

When effectively executed, the IDOV roadmap brings an organization closer to achieving ‘Six Sigma’ levels of performance by ‘designing in’ these expectations into the system/product development process. Key topics of Design For Six Sigma (DFSS) are as follows:

• IDOV (Identify, Design, Optimize & Validate) roadmap
• Voice of the Customer (VOC)
• Quality Function Deployment (QFD)
• TRIZ & Design Alternatives
• Design for Assembly & Manufacturability (DFM)
• Design Selection using Pugh/SDI Matrix
• Design FMEA (DFMEA)
• Hypothesis Testing
• Statistical Modeling with Design of Experiment (DOE)
• Sensitivity Analysis
• Monte Carlo Simulation
• Statistical Tolerance Allocation
• Capability Score (Short-Term)
• Error-Proofing for Process/Design
• SPC & Control Plans
• DFSS Scorecard
