Abstract

To minimize the products development time, increase the quality of products, reduce cost and meet the requirements of customers have become crucial in nowadays enterprise competition. The attitude of product design concept has been changed from passive response to be more aggressive in design process control. Designers can discuss in advanced and avoid problems during the later develop stages. There are many design control strategies to evaluate all possible issues and avoid the time and cost waste from improper design. Quality function deployment (QFD) is a method to transform user demands into design quality, to deploy the functions forming quality, and to deploy methods for achieving the design quality into subsystems and component parts, and ultimately to specific elements of the manufacturing process. The aim of this case study is to improve the design methodology through the integration of proactive methods with basic elements of the design process. This research paper will provide a general overview of the QFD methodology and approach to product development process, assess the root causes, Pareto analysis has been made to prioritize the causes, and literature is reviewed to determine key elements of the design process and proactive methods. The proposed analysis is the integration of Quality Function Deployment, which is the core finding of the study that fills the research gap, is selected and its methodical procedure is developed to complete the proposed methodology. So this study shows, that how to improve the design methodology by integrating the QFD and also this study will be important to help us understand how can prevent later design changes and increase products success especially in terms of quality and reliability.
