DFSS (Design for Six Sigma)
Design Processes
Applying Six Sigma principles to the design process.
In practice
Design for Six Sigma (DFSS) is a methodology applied during the design process to achieve high levels of product quality and customer satisfaction. By integrating Six Sigma principles into the design phase, DFSS aims to minimize defects, reduce variation, and optimize performance. DFSS emphasizes a data-driven approach, focusing on meeting customer requirements and continuously improving the design process to deliver products with exceptional quality and reliability.
Questions
What is DFSS (Design for Six Sigma)?
Design for Six Sigma is a methodology for designing products that meet quality targets from launch, rather than improving them after the fact.
Why do you use DFSS (Design for Six Sigma)?
Fixing variation after production starts is expensive and slow. DFSS moves that work into the design phase where changes are cheap.
How do you use/apply DFSS (Design for Six Sigma)?
Follow a defined sequence — usually define, measure, analyse, design, verify — with statistical evidence at each gate rather than opinion.
When do you use DFSS (Design for Six Sigma)?
In high volume manufacturing where the cost of variation is significant.
Who uses DFSS (Design for Six Sigma)?
Quality and design engineers in manufacturing organisations.
