All house’s parts are accurately structured and represented. The roof of the house reflects the interrelationships between the independent technical requirements or technical descriptors, in this part is achieved the tradeoff between conflicting and similar technical requirements. The house’s ceiling contains the technical descriptors or voice of the organization. The central part of the house describes the relationships between the customer requirements and technical requirements, the customer requirements or customer voices are transferred into the engineering requirements or technical descriptors. If we talk about the outside walls of the house, the left wall represents the customer requirements (voice of the customer) and the right wall depicts their priorities (prioritized requirements) that were obtained in result of customers’ survey. Finally, at the bottom of diagram (house’s floor) is represented the prioritized technical descriptor.

Example 7: House of Quality Interrelationship Matrix

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the House of Quality Solution. An experienced user spent 5 minutes creating this sample.

This House of quality sample shows the interrelationship matrix. One of the steps in the process of building the House of quality matrix is comparison the VOC (voice of the customer) with technical characteristics and also determination their interrelationships. This sample visually reflects the complete interrelationships between VOC and technical requirements. Typically, for representation the nature of relationship between customer requirements (WHATs) and technical descriptors or technical requirements (HOWs) are used the common symbols. The relationships between customer requirements and technical descriptors (WHATs vs. HOWs) can be strong, medium or weak. According to the offered legend, the strong relationship (scored as +9) is designated by solid circle, the medium relationship (scored as +3) is marked by single circle, and weak relationship (scored as +1) is represented by triangle. The cell is left empty in case of absence the relationship between VOC and technical characteristics, or when existing relationship is insignificant.

This sample represents the scheme depicting the main steps of sequential application the Quality function deployment (QFD) methodology for construction the House of quality (HOQ) matrix. The Quality Function Deployment (QFD) is a well known methodology of systematic and structured conversion the consumers’ needs into requirements for quality of product, service, or process. This methodology effectively contribute for better understanding the consumers in a process of designing, development and improvement products, it helps to ensure that the “voice of the customer” was heard when developing products and respective manufacturing operations. The Quality function deployment process starts with definition the list of goals or objectives, which are named WHATs and reflect the customers’ needs and expectations in a particular product. Then this list is extended and specified with secondary customer requirements, and there are defined the engineering characteristics (HOW’s), which will affect the customer perception (VOC) and will satisfy one or more listed customer requirements.

Example 11: House of Quality VOC vs Technical Requirements

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the House of Quality Solution. An experienced user spent 5 minutes creating this sample.

This House of quality sample diagram shows the VOC (voice of the customer) vs. technical requirements. According to the Quality function deployment methodology the customer needs and expectations are represented as the customer requirements (WHATs). The implementation of customer requirements can be executed only when they are transformed into the technical characteristics or technical requirements (HOW’s). So, in terms of QFD need to be developed the set of engineering characteristics satisfying the customer requirements and customer perception, i.e. the VOC. These technical characteristics are expressed in terms of technical language and specifications. This House of quality matrix is a simple scheme, which can be easily extended during the QFD process and transformed in a complete House of quality matrix with the help of tools of House of Quality solution from the Quality area of ConceptDraw DIAGRAM Solution Park.
