Quality Function Deployment Matrix

The Quality Function Deployment (QFD) Matrix is a tool used in product development and quality management to translate customer requirements (the 'what') into technical specifications (the 'how'). It helps ensure that the final product meets customer expectations by systematically linking customer needs to engineering characteristics.

At a very high level, the Quality Function Deployment Matrix is used in the context of business, quality management, product development.

What is the Quality Function Deployment Matrix?

A visual explanation is shown in the image above. The Quality Function Deployment Matrix can be described as a matrix with the following quadrants:

  1. Customer Requirements: Lists the features and attributes that customers expect from the product. Example: 'High fuel efficiency'
  2. Technical Descriptors: Outlines the technical specifications and features that will fulfill the customer requirements. Example: 'Engine performance metrics'
  3. Relationship Matrix: Shows the correlation between customer requirements and technical descriptors. Example: 'High fuel efficiency' correlates with 'Engine performance metrics'
  4. Competitive Benchmarking: Compares the product's features and performance against competitors. Example: 'Fuel efficiency rating compared to competitors'

What is the purpose of the Quality Function Deployment Matrix?

The Quality Function Deployment (QFD) Matrix, also known as the House of Quality, is a structured method used to transform customer needs and requirements into detailed engineering specifications. The matrix is typically used in the product development process to ensure that the voice of the customer is captured and translated into specific technical requirements that can be measured and controlled.

The QFD Matrix consists of several components, including customer requirements, technical descriptors, a relationship matrix, and competitive benchmarking. The matrix is divided into four quadrants:

  • Customer Requirements (What): This quadrant lists the features and attributes that customers expect from the product.
  • Technical Descriptors (How): This quadrant outlines the technical specifications and features that will fulfill the customer requirements.
  • Relationship Matrix: This quadrant shows the correlation between customer requirements and technical descriptors, indicating how well each technical feature satisfies customer needs.
  • Competitive Benchmarking: This quadrant compares the product's features and performance against competitors, helping identify areas for improvement and differentiation.

Use cases for the QFD Matrix include new product development, process improvement, and quality management. For example, a car manufacturer might use the QFD Matrix to ensure that customer desires for fuel efficiency, safety, and comfort are translated into specific engineering targets like engine performance, safety features, and interior design.
