As part of a QFD project, use the House of Quality Matrix 1 to evaluate the relationship between customer requirements and performance criteria. The House of Quality matrices document the phases of product development from customer requirements to assembly.
Answers the questions:
- What is the relationship between customer requirements and performance criteria?
- What is the relationship between performance criteria?
- How well does your most similar product or service meet the customer's needs?
- How does your product compare to your competitors' products?
- 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.
This form uses the customer requirements that you entered in the Pairwise Comparisons Matrix.
As a cross-functional team, complete the following steps:
- 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.
- Evaluate the relationship between each performance criterion and each customer requirement to determine the following:
- The critical relationships: blank is none; 1 is weak; 3 is moderate; and 9 is strong
- The level of difficulty that is required to achieve the target value for each performance criterion.
- Rate how well your competitors' products or services deliver a specific requirement.
The Performance Criteria Interactions Table, also called the technical correlation matrix, is the roof on a traditional House of Quality.
- Complete the House of Quality Matrix 2.
