33 Facts About House Of Quality

What is House of Quality?

House of Quality (HoQ) is a part of the Quality Function Deployment (QFD) process. It helps organizations translate customer needs into engineering characteristics for a product or service. Let's dive into some fascinating facts about this powerful tool.

1. Origin: HoQ was first developed in Japan in the late 1960s by Mitsubishi's Kobe shipyard.

2. Purpose: It aims to ensure that the voice of the customer is heard and incorporated into the design and production process.

3. Structure: The HoQ matrix resembles a house, with a roof, body, and foundation, hence the name.

4. Customer Needs: The left side of the matrix lists customer requirements, often called "whats."

5. Technical Descriptors: The top of the matrix lists technical requirements, known as "hows."

6. Relationships: The body of the matrix shows the relationship between customer needs and technical descriptors.

7. Prioritization: It helps prioritize which technical requirements are most important based on customer needs.

8. Competitive Analysis: The right side of the matrix often includes a competitive analysis to compare how well competitors meet customer needs.

9. Correlation Matrix: The roof of the house shows the correlation between different technical requirements.

10. Target Values: The bottom of the matrix includes target values for each technical requirement.

Benefits of Using House of Quality

Understanding the benefits of HoQ can help organizations appreciate its value and implement it effectively.

11. Customer Focus: HoQ ensures that customer needs are at the forefront of the design process.

12. Improved Communication: It fosters better communication between different departments within an organization.

13. Reduced Development Time: By clarifying requirements early on, HoQ can help reduce the time needed for product development.

14. Enhanced Quality: Products designed using HoQ are more likely to meet customer expectations, leading to higher quality.

15. Cost Savings: By identifying key requirements early, organizations can avoid costly redesigns and modifications later.

16. Competitive Advantage: HoQ can help organizations develop products that outperform competitors in key areas.

17. Risk Management: It helps identify potential risks and challenges early in the design process.

18. Documentation: HoQ provides a clear and structured documentation of the design process.

Steps to Create a House of Quality

Creating an HoQ involves several steps, each crucial for its success.

19. Identify Customer Needs: Gather and list customer requirements through surveys, interviews, or focus groups.

20. Determine Technical Requirements: Identify the technical aspects that will meet the customer needs.

21. Relate Customer Needs to Technical Requirements: Fill in the matrix to show how each technical requirement addresses customer needs.

22. Conduct Competitive Analysis: Compare how well competitors meet these customer needs.

23. Set Target Values: Establish target values for each technical requirement to guide the design process.

24. Analyze Correlations: Use the correlation matrix to identify how different technical requirements interact with each other.
