Teknomekanik, 2022

To utilize the concept of Quality Function Deployment (QFD) and apply it appropriately to address design decisions concerning the quality of cellular phones, a simplified version of the House of Quality (HoQ) will be built. Real customer requirements (CRs) are easier to collect when QFD is employed because it puts the emphasis on the customer and their demands where it should be. After gathering various users' opinions on different smartphone brands and conducting an online survey with mobile users in Taichung, Taiwan, the study highlights the items preferred by most users, such as long-lasting battery life, high-quality camera, reliability, wide screen, ease of use, and lightweight. This aids businesses in translating CRs into primary Design Requirements (DRs) so that they can create superior goods that align with consumer demands.

Mobile phone selection based on a novel quality function deployment approach

Soft Computing, 2020

Fuzzy quality function deployment (QFD) approach has been extensively implemented to transform customer requirements (CRs) into products or services because fuzzy numbers provide to obtain more accurately the judgments of experts in vagueness environment. This study proposes to use interval type-2 fuzzy (IT2F) numbers in the improving of fuzzy QFD method. The developed IT2F number-based QFD approach utilizes IT2F sets to define the correlations among CRs; the relations between CRs and design requirements (DRs); the correlations among DRs; the weights of DRs. There is no paper about integrating QFD approach and IT2F set in the literature. IT2F numbers include more accurately the judgments of the experts to express the vagueness of the applications. In addition, TOPSIS (technique for order performance by similarity to ideal solution) approach based on interval type-2 trapezoidal fuzzy (IT2TrF) is utilized to select the best mobile phone. Finally, mobile phone selection implementation is handled to indicate the efficiency of the proposed method.

Quality Function Deployment for Incorporating the Need of the Customers for Product Development and Design

2013

There are wealth of studies which show the desirability of involving real customers in the design process so that the problems customers have with the product can be examined and eliminated before the actual production starts. The Total Quality Management (TQM) provides tools for the benefits and involvement the customers. A product is also developed for the customer. Hence the objective of two fields are same – The customers. Hence when these two fields work together the product will definitely be the result of actual customer ideas, When the focus is on the customers then the significance of the ergonomics also cannot be omitted as it also works for the satisfaction of the customers. In this paper an attempt is made to develop a methodology to involve the customers in ergonomic product development and design. The TQM tool selected for the purpose is Quality Function Deployment (QFD). The product Air Conditioner is used for the application of QFD.

A Quality Function Deployment Methodology for Product Development

A constant challenge for any fast paced industry, such as consumer electronics, is the very short technology life span needed to successfully take a product from conception to market while staying competitive with other industry leaders. There are also a wide variety of customers and market segments. Incorporating these factors into a single product design while maintaining a competitive development cycle is both challenging and time consuming. Customer input is gathered through marketing surveys, market research and previous product feedback. Implementing this paper adds to the overall product lead time due to the difficulty of gathering and analyzing the data. This lead time can be reduced by creating a method to process the voice of the customer for direct use in the development cycle. In the consumer electronics industry (similar to other fast paced industries), there are 3 basic types of customers: "early technology adopter", "general consumer", and "last to market" [20]. Currently corporations target either a single customer type with their product family, or choose to make a range of products to meet, hopefully, the needs of each of these types. In a survey of the literature, there are no documented end to- end methods for interpreting and applying marketing survey data (that is generalized and not targeted towards a specific group) and producing product/feature sets that reflect the needs of each customer group that can be input directly into the quality function deployment process. This paper will present an end-to-end process that can take a product concept, gather and analyze customer marketing data, create a product profile/feature set, and use input from the cross functional teams to maximize the end quality, and customer satisfaction. This tool would be extendable to any "fast paced" industry, such as the consumer electronics industry, and reduce development costs lead time, reduce internal decision time, turn qualitative into quantitative reasoning. The following literature review will show the previous research in areas of product development and quality function deployment related to the goal of this paper.

A Case Study on Improvement of Conceptual Product Design Process by Using Quality Function Deployment

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.

An application of quality function deployment to functional modeling in a knowledge intensive design environment

Springer eBooks, 1996

Knowledge intensive design environments should assist designers with clear understanding of designers' intention. Therefore, relating functional information of a design object with the designer's intention is a crucial issue. We have already proposed the FBS (Function-Behavior-State) diagram as a framework for modeling function. An FBS diagram represents the information on function, behavior, and state of one design solution, but it cannot deal with design alternatives that are considered in a design process. This results in the FBS diagram being lacking the representation of the reasons why the designer selected one solution from alternatives. QFD (Quality Function Deployment) is a method for design review and allows the designer to evaluate a design object from view point of quality. This paper proposes an application of the QFD method to the FBS diagram to represent the designers' intention for decision making during design. We also describe a prototype system and illustrate an example design of a photocopier to demonstrate how a knowledge intensive design environment can contribute to guaranteeing and improving design quality.
