What is House of Quality?
House of Quality is
- A diagram, resembling a house,
- Used for defining the relationship between customer desires and the firm/product capabilities.
- A part of Quality Function Deployment.
- Utilizes a planning matrix to relate what the customer wants to how a firm (that produces the products) is going to meet those wants.
- Identifies and classifies customer desires
- Identifies the importance of those desires
- Identifies engineering characteristics which may be relevant to those desires
- Correlates the two, allows for verification of those correlations
- Assigns objectives and priorities for the system requirements
- This process can be applied at any system composition level (e.g. system, subsystem, or component) in the design of a product, and
- Can allow for assessment of different abstractions of a system.
Steps to the House of Quality:
- Identify the Customer Requirements – Voice of the Customer (WHATs)Primary Customer RequirementSecondary Customer Requirements under aestheticsSecondary Customer Requirements under Performance
- Identify the Technical Requirements – Voice of the Engineer (HOWs)
- Develop the Relationship Matrix between WHATs and HOWs
- Describe the Inter-relationship (Correlation) Matrix between HOWs
- Competitive Assessment
Customer Competitive Assessment
Technical Competitive Assessment
- Develop prioritised Customer requirements
- Develop prioritised Technical Descriptors
Outputs:
Output of House of Quality
- Generally a Matrix with customer desires on one dimension and correlated non-functional requirements on the other dimension
- The cells of matrix table are filled with the weights assigned to the stakeholder characteristics where those characteristics are affected by the system parameters across the top of the matrix
- At the bottom of the matrix, the column is summed, which allows for the system characteristics to be weighted according to the stakeholder characteristics.
- System parameters not correlated to stakeholder characteristics may be unnecessary to the system design and are identified by empty matrix columns
- While stakeholder characteristics (identified by empty rows) not correlated to system parameters indicate "characteristics not address by the design parameters”
- System parameters and stakeholder characteristics with weak correlations potentially indicate missing information
- While matrices with "too many correlations" indicate that the stakeholder needs may need to be refined.
