House of quality is an excellent quality-planning tool. It is also known as product planning matrix or matrix diagram. it consists of six major building bocks:
1) Customer requirements (WHAT’S)-a structured list of customer requirements.
2) Technical requirements (HOW’S)-a structured set of relevant and measureable products or service characteristics.
3) Inter-relationship matrix-illustrates the QFD teams perceptions of inter-relationships between customer requirements and technical requirements. The degree of relationship is marked using symbols.
4) Technical correlation (roof) matrix-used to identify where technical requirements support or impede each other in the product or service design.
5) Planning matrix-illustrates relative importance of customer requirements, customer perception of company and competitor performance in meeting customer requirements. It is also contains prioritized customer requirements.
6) Prioritized technical requirements

Tips for Success of QFD
•A consultant is needed to guide through at least the first few projects
•The activity should be a formal activity and every member should take part, fully prepared.
•The meetings should be planned at regular intervals for shorter duration so as to get the best out of this exercise through maintaining focus.
Tips for Success of QFD
•Elicitation and recording customer requirements is key to success. In the area of software development the Unified Modeling Language (UML) diagrams are used to capture the requirements. Similar techniques should be adopted to gather all the stated and unstated requirements of the customer.
•The new seven management tools should be applied at various stages to get better results.
•Believe that “we don’t know all the requirement of the customers” will lead to success.
