House of Quality Matrix 3

As part of a QFD project, use the House of Quality Matrix 3 to evaluate the relationship between design parameters and process parameters. The House of Quality matrices document the phases of product development from customer requirements to assembly.

Answers the questions:
  • What is the relationship between design parameters and process parameters?
  • What is the relationship between process parameters?
  • How well does your most similar product or service meet the customer's needs?

Guidelines

  • Always complete a House of Quality as a cross-functional team.
  • A House of Quality is only one component of an entire Quality Function Deployment (QFD).
  • A House of Quality is a living document and a source of reference for future upgrades.

How-to

This form uses the design parameters that you entered in the House of Quality Matrix 2.

As a cross-functional team, complete the following steps:
  1. Add columns to the matrix to create a list of process parameters that define the product or service.
  2. Evaluate the relationship between each process parameter and each design parameter to determine the following:
    • The critical relationships
    • The level of difficulty that is required to achieve the target value for each process parameter.
  3. (Optional) You can assign the process parameter to the functional areas that you define.
    Note

    The Process Parameter Interactions Table, also called the technical correlation matrix, is the roof on a traditional House of Quality.
