Quality function is a very dynamic topic and also House of Quality is a very flexible model that many researchers have developed in case of different subjects and areas. This paper has tried to explain three of them; a new model for prioritizing design requirements, a proposed approach that integrate Kano’s model into QFD and a knowledge based approach to QFD. Of course, these new approaches may also have some deficiencies but as mentioned earlier, it is a very progressive topic that further researches will remove these deficiencies and make QFD applicable for different areas efficiently and effectively.
