House of Quality Matrix 1

Use the House of Quality Matrix 1 to evaluate the relationship between customer requirements and performance criteria.

The House of Quality Matrix 1 answers the following questions.
  • What is the relationship between customer requirements and performance criteria?
  • How well do your products meet the needs of your customers?
  • How do your products compare with the products of your competitors?

How-to

This form uses the customer requirements from the Pairwise Comparison Matrix.

As a cross-functional team, complete the following steps.
  1. Add columns to the matrix to create a list of performance criteria that define the product or service. The criteria should be top-level, solution-independent measurements or metrics.
  2. Rate the strength of the relationship between each performance criterion and each customer requirement. Blank is none, 1 is weak, 3 is moderate, and 9 is strong.
  3. Rate the level of technical difficulty for each performance criterion.
  4. Rate how well your competitors' products or services meet a specific requirement.
    Note

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

  5. Complete the House of Quality Matrix 2.

House of Quality Matrix 2

Use the House of Quality Matrix 2 to evaluate the relationship between performance criteria and design parameters.

The House of Quality Matrix 2 answers the following questions.
  • What is the relationship between performance criteria and design parameters?
  • How well do your products or services meet the customer's needs?
  • How does your product compare to your competitors' products?

How-to

This form uses the performance criteria from the House of Quality Matrix 1.

As a cross-functional team, complete the following steps.
  1. Add columns to the matrix to create a list of design parameters that define the product or service.
  2. Evaluate the relationship between each design parameter and each performance criterion. Blank is none, 1 is weak, 3 is moderate, and 9 is strong.
  3. Rate the level of technical difficulty for each design parameter.
  4. Rate how well your competitors' products or services meet a particular requirement.
  5. You can assign the design parameters to the functional areas that you define.
  6. Complete the House of Quality Matrix 3.

House of Quality Matrix 3

Use the House of Quality Matrix 3 to evaluate the relationship between design parameters and process parameters.

The House of Quality Matrix 3 answers the following questions.
  • What is the relationship between design parameters and process parameters?
  • How well do your products or services meet the customer's needs?

How-to

This form uses the design parameters from 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. Blank is none, 1 is weak, 3 is moderate, and 9 is strong.
  3. Rate the level of technical difficulty for each process parameter.
  4. You can assign the process parameter to the functional areas that you define.
