In today’s competitive market, companies continually need to keep themselves updated with the changing demand of the customer. The customer now has a wide variety of products at competitive prices to choose from. In order to survive in this stringent competition, it is very important to monitor the requirements of the consumer. This is where Quality Function Deployment plays an earnest and unfathomable role. Quality Function Deployment (QFD) is a veracious process, which helps to determine product development characteristics, which includes technical requirements based on customer preferences. With the use of integrated matrix called House of Quality, the process considers the various influences acting during the design to promote concurrent engineering, leading to aggrandize product acceptance. It is a planning tool used to fulfill customer expectations including important quality assurance points, which would be used until the production stage. This paper gives a systematic method to generate House of Quality with an example of an air conditioner. Application of this tool not only saves time and efforts to manufacture a new air conditioner, but also reduces risks related to the launch of a new product in the market because of increasing competitiveness with other existing brands.
