Vehicle Wiring QFD, D. Carter, K. Hasenstab and S. Schafer, Electro-Wire; R. Uroda, Ford B&AGO. The QFD core team consisting of design engineering, advanced systems engineering, product engineering, and QA from Electro-Wire and Ford reports their pilot QFD efforts. The project involved application of QFD in the design, manufacturing, and assembly of the wiring harness for an entire vehicle. The objectives were to learn QFD methodology, establish foundation for future vehicles and impact current vehicle. The paper reports the steps taken and the resulting benefits.
Pre-Planning a Total Product:. The Key to Success in Complex Product Development Situations, C. W. Kurowski, Chrysler Motors. Utilization of QFD sometimes resulted in a very long customer requirements list. This adds complexity to product planning and development of large and complex products. Using QFD as a tool to help systemize the total process plan, a macro "Pre-Planning QFD" has been developed to organize data to determine the two or three important product characteristics that will enhance the product for increased customer satisfaction. This paper explains this new concept and matrix.
QFD: A Systems Approach to Brake Design, T. J. Bodell and R. A. Russell, Kelsey-Hayes Company. Kelsey-Hayes began using the concepts of the QFD process in 1986 and had done a couple of studies on developed components. A new vehicle program at one of the Big Threes directed them into the next study, which turned out to be a complete systems QFD study encompassing new products as well as all of the KH products. The paper reports their progress to date in the on-going initiatives.
Front End Accessory Drive Design - A QFD Approach, R. Ahoor, Ford/Engine Product and Manufacturing Engineering. The front end accessory drive belt drive system was chosen for a QFD study, because of the extremely challenging performance and warranty objectives. This paper reports the benefits of the QFD experience specifically as it applied to the modular engine program, including the relationship of QFD to the use of engineering tools such as simulation program, design of experiments and cross-functional team approach for system design.
SMC Truck Hood, M. Gavoor and G. Marcel, Rockwell International; Greg MacIver, Ashland Chemical. This paper provides an insight to Rockwell International Automotive Operation's philosophy and approach to QFD highlighting the SMC Truck Hood project. This project illustrates the organizational commitment necessary to successfully implement QFD. How QFD and existing product development procedures were integrated is explained.
QFD: A Road Map for Survival in the 1990's, D. Makie, Masland Industries. Why can the Japanese introduce a new vehicle in half the time and with superior quality than the U.S. auto companies? A large part of the answer seemed to be QFD. For this reason, Masland employed QFD as a strategy for survival in the 1990's. This case study, the company's second QFD efforts, involved the development of a full floor carpet system. This reports explains how QFD principles were put to work in a step-by-step fashion and what they have learned through the process.
1990: 2nd Symposium on QFD (ISBN1-889477-02-8)
Overview of Quality Function Deployment, R. J. Dika, Chrysler Corporation. Within the community of quality and reliability professionals, there has been an explosion of interest in QFD, study and discussion on the subject. This paper presents in a global way, a statement of what QFD is and a brief description of its universal elements, essential principles, and mechanics and definitions, with intent to set a common starting place for all Symposium participants.
Steering Column Concept Selection for Low Cost and Weight, R. L. Begley, Chrysler Corporation. Most engineers approach the "Design" sequence in fashions which they have learned while on the job. Very little formal training exists at the university level which translates directly into how an engineer might choose the appropriate design for the task at hand. Additionally, very few corporations offer courses instructing the engineering community on what techniques should be used to select an appropriate design and then to improve it. Through an example of the selection process for a steering column assembly experience at Chrysler, this paper demonstrates the application of QFD, Competitive Benchmarking and Value Engineering as very powerful tools for the engineer to use in the design process.
Ford - GE Blower Motor Project, H. Wadke and A. Palumbo, Ford Motor Corporation; M. Cicala, American Supplier Institute. Presentation slides on an application of QFD in the Ford-GE blower motor project.
Quality Improvement - Start at the Beginning with QFD, W. H. Selecman, Ernst & Young. Most companies in the Automotive Industry are having great difficulty implementing SPC. They are typically satisfying Big 3 requirements but harvesting few benefits. This article discusses the rationale and impact of changing the approach for attaining quality improvement to employ QFD to focus more heavily on refining activities that must be done precisely. A series of lessons learned in instructing and applying QFD to automotive products are included. The linkage between QFD and other elements of the quality tool kit are explored.

Concept Development Through Teamwork - Working for Quality, Cost, Weight and Investment, Robert J. Dika and Ray L. Begley, Chrysler Corporation. This paper resents a method for developing a product design and manufacturing process concept, before project final approval, which integrates several other methodologies and uses cross-functional teams. It is a method for completing a "paper" study which quickly considers many of the downstream stems of product development, which will be conducted in greater detail later. It results in a selection of the best design and process for the overall product application and supports this selection with sound numerical targets for quality, cost, weight, investment and process capability.
Application of a QFD and Other Quality Tools to a Trunk System, Bill Biondo, General Motors. A QFD application case study presented by General Motors. The project goal was to produce a quality trunk system which meets or exceeds the customers expectations by understanding the customer's requirements, and the resulting product, process and production floor requirements. The process began with the VOC, translation of the voice into product characteristics, and assessment of strength of the characteristic relationships. Competitive benchmarking was done to determine the priority of each characteristics and the level of complexity. The processes continued from system to component to process to production floor. At each level, the critical elements were focused on and studied.
1992: 4th Symposium on QFD (ISBN1-889477-04-4)
The Utilization of QFD in the LH Powertrain Program, Glenn W. Czupinski, Don H. Kerska, Chrysler Corporation. The LH was the first major program at Chrysler Corporation to use QFD beginning at the total vehicle level and then prioritizing critical system areas for more detailed study. The LH powertrain project was one of five strategically identified areas requiring further analysis. As a result of the QFD study, four critical subsystems of the LH powertrain were identified needing extra design attention in order to ensure customer satisfaction. The paper discusses the challenge to the engineers and the major benefits of implementing QFD in this project.
Reducing Time to Market for New Products: QFD in Action, Kevin O'Brien, Ph.D., Raychem Corporation. This project illustrates how QFD can be used to significantly reduce the time to market required for the development of new products. Focusing on the automotive industry, the paper explains how this can be achieved using the matrix approach to analyze critical processes to determine critical process parameters and coupling the information with designed experiments and SPC to assist in improving the final product delivered to the customer.
1993: 5th Symposium on QFD (ISBN1-889477-05-2)
QFD Implementation at Chrysler - The First Seven Years, Robert J. Dika, Chrysler Corporation. QFD appears to be a simple and rational method to translate customer requirements into appropriate company technical requirements. It is also the nature of QFD to challenge some of the basic assumptions and traditions of the new product development systems in mature organizations. Since it demands a change in the ways that we think and act as a company, it will meet resistance. This paper presents the story of successes and struggles that Chrysler has experienced in the integration of QFD into its development process. It reports the steady growth in both the number and significance of QFD projects over a seven year period, and shows that QFD can be a strategy in the movement toward a TQM culture.
Utilization of QFD Principles In Chrysler's 1995 Small Car Program, Monte G. Myers, Chrysler Corporation. Is it possible for an American automobile manufacturer to design and build an affordable, fun to drive small car, in North America and at the same time make a profit? Chrysler's Small Car Platform Team not only believes that this is possible, but is on the verge of proving it to the world. This team has continually challenged itself to "Dare To Be Different" in all aspects of the automobile design and development process in an effort to challenge this paradigm. This paper presents a case study of a large scale, total vehicle program. It discusses the QFD process as used by Chrysler's Small Car Platform Team during the design and development phases of the new small car slated for an early 1995 model year introduction.
Application of QFD to Launch of G.M. D-Car Air Bag, Leonard Pavia, Mexican Industries in Michigan, Inc. As a tier two supplier for air bags, Mexican Industries does not interact with the end item customer to be involved in the first phase of QFD in determining the customers demands or wants and translating them into design requirements. However, the company does become actively involved in Phase Two "Part Deployment," Phase Three "Process Planning" and Phase Four "Production Planning." This paper explores the application of these three phases of QFD to a vary unique air bag designed to meet the customer demand of protecting not only the regular passenger but also the third person sitting in the front seat.
Volvo's E.C.C. (Environmental Concept Car) - QFD applied to a Future Concept Car, S. Voegele, Volvo Monitoring and Concept Center. While the majority of the world's automakers are involved in intense R&D of battery-powered electric cars that will meet the CAFE requirements, Volvo has taken a different view: Meet California's zero emission vehicle standard set for 1998 but also take the desires of Volvo customers into consideration. The voice of the Volvo customer guided the entire concept development process. Using QFD as a concept development tool provided product requirements that were surprisingly different from initial expectations.
Strategic Management of (Standard) QFD, Keith B. Termaat, Ford Motor. After five years of QFD, things right and things wrong with QFD were evaluated to specify a Ford standard process to achieve faster cycle time, reduced engineering workload and better direct marketing research and software institutional support. This paper describes a Ford proprietary QuickQFDTM process which relies on templates for wants, hows, and interactions to rapidly focus on no more than a couple of dozen each.
Aligning The Product Development Process Using Momentum(R) QFD: A Case Study In Letting The Voice Of The Customer Drive The Conceptualization Of a New Leak Detector, R. Norman, Leemak Training Systems, Inc. Using a case study, this paper examines the phases a company went through to implement a process for concurrent product development. The first phase included Voice of the Customer alignment and tools, the second phase embodied the tools and techniques of QFD, and the third phase involved implementing the plan.
1994:
6th Symposium on QFD (ISBN1-889477-06-0) Making The Neon Fun To Drive, J.E. Fernandez, J.L. Chamberlin, E.G. Kramer, J.H. Broomall, H.A. Rori, and R.L. Begley, Chrysler Corporation. The paper recounts the QFD and PDCA efforts utilized by Chrysler's Small Car Platform teams in the development of the "Fun to Drive" steering and suspension characteristics of the 1995 Neon. Starting with customer requirements, the teams established the relationship of the requirements to engineering measurements at the vehicle level and identified which of the important vehicle characteristics were associated with what vehicle components. The project resulted a profitable small car program in North America. The QFD process brought all parties to become of a single mind and work in concert toward a specific goal - Fun to Drive, QFD.
Statistical Consistent Transformation Algorithm For Output Calculations Within The QFD Matrix, R. Vrancken, Siemens Automotive. The basic concept of the QFD matrix is to translate requirements of any kind (Whats) into controllable characteristics (Hows). QFD cascading systems use the How-importance ranking of a first matrix as What-importance ranking for a next matrix. Using the statistical probability distribution of What-values and the matrix elements to calculate the importance ranking of Hows, an algorithm was developed by a team at the Central Quality Division of the Siemens Company in Munich Germany. The paper describes this algorithm and report an application at Siemens Automotive Division in Ontario Canada.
1995: 7th Symposium on QFD (ISBN1-889477-07-9)
QFD Status in the U.S. Automotive Industry, Harold Ross and Kioumars Paryani, GM Systems Engineering Center, NAO Engineering Center, General Motors Corporation. As Dr. Akao has stated in many of his lectures, mass production has caused a great separation between the workers and the customer, both in distance and in layers of management. In large organizations that cannot deal on an individual basis with the customer, QFD is being used to translate customers wants and needs into technical requirements. This paper attempts to provide a brief description of the current usage, integration, and understanding of the QFD process within the context of General Motor's product development process.
Fuelguard Lower Tie Plate Product and Process Re-Design Using QFD and Robust Design, D. Adams and G. Waymire, Siemens Power Corp., S. Macfarlane, Black Sheep Engineering Services, and P. Walsh, Ehrhardt Tool and Machine. A multi-functional team from Siemens and vendors redesigned a fuel assembly component, using QFD and Robust Design. The initial product design met an important customer requirement, while improvements in the manufacturing process were being considered. The team used quality deployment and Pugh Concept Selection to generate a new concept and Robust Design to optimize the product. Process deployment using QFD further enhanced the manufacturing capability. The new design reduced manufacturing costs and time by approximately 40% and improved the quality and strength of the component.
