"After drafting the relationship matrix, it is evaluated for any empty row or column. An empty row indicates that a customer voice is not being addressed by any technical descriptors. Thus, the customer expectation is not being met. Any blank column indicates that the technical requirement is unnecessary, as it does not address any VOC.
The roof of the house of quality, expressed as correlation matrix, is used to identify any interrelationships between the technical descriptors (Figure 3-5). Symbols are used to describe the strength of the interrelationships. Symbols generally preferred are:
- A ‘solid circle’ represents a strong positive relationship.
- A ‘circle’ represents a positive relationship.
- An ‘X’ represents a negative relationship.
- An ‘asterisk’ represents a strong negative relationship." [nptel.ac.in/ courses/ 110101010/ modules/ module3/ lec1/ 1.7.html]

This interior design sample shows the layout of furniture, kitchen and bathroom appliances on the house floor plan.
"A house is a building that functions as a home for humans or other creatures, including simple dwellings ranging from rudimentary huts of nomadic tribes and complex structures composed of many systems.
The social unit that lives in a house is known as a household. Most commonly, a household is a family unit of some kind, although households may also be other social groups or individuals.
Ideally, architects of houses design rooms to meet the needs of the people who will live in the house. Such designing, known as "interior design", has become a popular subject in universities." [House. Wikipedia]

"The house of quality, a part of QFD, 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, and then 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."

"The “house of quality,” the basic design tool of the management approach known as quality function deployment (QFD)...
The foundation of the house of quality is the belief that products should be designed to reflect customers’ desires and tastes—so marketing people, design engineers, and manufacturing staff must work closely together from the time a product is first conceived.
The house of quality is a kind of conceptual map that provides the means for interfunctional planning and communications. People with different problems and responsibilities can thrash out design priorities while referring to patterns of evidence on the house’s grid." [Hauser, John R.; Clausing, Don.

"Quality Function Deployment (QFD) uses a matrix format to capture a number of issues that are vital to the planning process. The House of Quality Matrix is the most recognized and widely used form of this method. It translates customer requirements, based on marketing research and benchmarking data, into an appropriate number of engineering targets to be met by a new product design. Basically, it is the nerve center and the engine that drives the entire QFD process." [Tapke, Jennifer; Muller, Alyson; Johnson, Greg; Siec, Josh.

"The West Wing of the White House, also known as the Executive Office Building, houses the offices of the President of the United States. The West Wing contains the Oval Office, the Cabinet Room, the Situation Room, and the Roosevelt Room.
The West Wing's three floors contain offices for the White House Chief of Staff, the Counselor to the President, the Senior Advisor to the President, the White House Press Secretary, and their support staffs. The Vice-President has an office in the building, but his primary office is next door in the Eisenhower Executive Office Building." [West Wing. Wikipedia]

This plumbing and piping plan sample depicts the house hot and cold water supply and sanitation system.
"Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. ...
Plumbing is a piping system with which most people are familiar, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and businesses. Plumbing pipes also remove waste in the form of sewage, and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport nonpotable or potable water, or other fire-suppression fluids." [Piping. Wikipedia]

"Product Design. Initially, information about customer requirements must be collected. Once done, these should be converted into qualitative properties in the form of design. A tool used to facilitate this is the House of Quality, which is based on a number of processes that generally follow the list below.
1. Customer characteristics
2. Priorities of customer characteristics (scale 1-5)
3. Technical characteristics
4. Relationships between customer and technical characteristics (1.3.9)
5. Competing products
6. Rating of products on the market by customer characteristics (scale 1-5)
7. Rating of products on the market by technical characteristics (scale 1-5)
8. Rating and comparison of measurable values ​​for product properties
9. The tool converts the information into measurable results
Then a more precise requirement specification can be made. Where product requirements and technical characteristics are developed in detail." [sv.wikipedia.org/ wiki/ Quality_ function_ deployment]

This house of quality sample illustrates prioritized technical descriptors.

"The technical competitive assessment makes up a block of rows corresponding to each technical descriptor in the house of quality beneath the relationship matrix. After respective technical factors have been established, the products are evaluated for each technical factor that addresses VOC.
Similar to the customer competitive assessment, the data recorded are in a scale of 1 through 5, to indicate a rating, 1 for worst and 5 for best. The technical competitive assessment is often useful in uncovering gaps in engineering judgment.
Importance ratings represent the relative importance of customer requirement in terms of each other.
The target-value of column can be on the same scale as the customer competitive assessment (1 for worst, 5 for best can be used). This column is where the QFD team decides whether they want to keep their product unchanged, improve the product, or make the product better than the competitor.
The prioritized technical descriptors make up a block of rows corresponding to the technical descriptor in the house of quality below the technical competitive assessment as shown in Figure 3-7. These prioritized technical descriptors contain target value and absolute weights." [nptel.ac.in/ courses/ 110101010/ modules/ module3/ lec1/ 1.9.html]
