QFD

 

What is QFD?

Quality Function Deployment (QFD) is a structured approach used in strategic planning and management to translate customer needs into specific design or process requirements. It has applications across various industries, including product development, marketing, and Six Sigma.

QFD is also known as:

  • Voice of the Customer (VoC)
  • Matrix Product Planning
  • Customer Product Planning

QFD in Six Sigma

In Six Sigma, QFD is used during the Define stage of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology to:

  • Gather customer requirements
  • Prioritize those requirements
  • Transform them into actionable design or process specifications

Key QFD Techniques

Some commonly used QFD techniques include:

  • House of Quality – A matrix-based tool for visualizing customer needs and technical requirements
  • Pugh Concept Selection – A decision-making method to evaluate multiple design options
  • Modular Function Deployment – A structured approach for modular product design
