  • Toyota was able to reduce 60% of cost to bring a new car model to market. Toyota decreased 1/3 of its development time
  • Quality function deployment (QFD), a key strategic link in the total quality management (TQM) chain World Class Design to Manufacture Volume 2 · Number 5 · 1995 · pp. 43–45 : MCB University Press · ISSN 1352-3074 2. It starts from the customer needs and coverts into technical specifications and also ensures the quality of customer needs through out the production process. 3.To effectively deliver value of the customers, it is necessary to listen to the voice of customer through out the product development Glenn H Mazur (1996), QFD institute , USA.
  • 1.QFD is a visual connective process that helps teams focus on the needs of the customers throughout the total development cycle. An International Journal, Vol. 7 No. 1, 2000, pp. 8-19. 2.In traditional approaches they were more concentrating on spoken customer needs and it was a qualitative method.
  • Step 1: Need to determine customer requirement using VOC, Kano ...and set the priority Step 2: Determine the technical requirement from the customers requirements. Step 3:engineering parameter relates to a customers’ requirements Step 4:Identify Relationships Between Engineering Requirements Step 5:how the customer perceives the competition’s ability to meet each of the requirements Step 6: Determine target value for each engineering requirement
  • Infosys Banking Software : Role of QFD 1.Success in Software requirement management will decide the success of the software product development 2. customer requirements to the software specifications 3. customer expectations are taken as Security, Availability, Globalization, Reliability, Response time and Ease of Use. 4. Which is the row wise cumulative sum of Importance multiplied by the relationship matrix value, for example For the need “Security” total score will be 95(5*1+5*9+5*9) 5. Calculate the Importance of How’s-Is the column wise cumulative sum of importance of the needs multiplied by the value of the relationship matrix 6.H- high M- Medium L- Low Ref: PROJECT MANAGEMENT LEADERSHIP CONFERENCE -2009, Infosys
  • 1.QFD is a tool. Like any tool, its applications are limited. It can help a company capture the voice of its customer, but it is not going to give an accurate feel for the mind of the customer. Bill Dickinson, World Class Design to Manufacture ,Volume 2 · Number 5 · 1995 · 43–45 2. QFD is a planning tool and organizes data in a logical and systematic way, but it is rather a qualitative method. The union of QFD with quantitative methods will yield even greater benefits from its application. Vivianne Bouchereau and Hefin Rowlands ,University of Wales College, Newport, South Wales, UK
  • 1. Modern QFD moved into include design, marketing, strategy , and knowledge management. 2.Including Statistical process for the calculation for more accuracy in calculations.
  • 1.QFD will be also positioned as an effective tool for quality assurance of systems 2. A machine-learning approach

  • 6. Traditional & Non-traditional ApplicationsIBM, Toyota ,Infosys, Mitsubishi , Tata,CanonInfosys : Banking Software
  • 7. Advantages:Product quality is superiorClient satisfaction is improvedReduce ◦ design time ◦ deliver and Manufacturing cost ◦ Design changes
  • 8. Limitations :Sometimes HOQ is too complexMarket Research RisksStability of customer requirementTraditional QFD is not flexible
  • 9. Future trendsFind more importance in how to align company wide activities to customer focus.Price design along with quality design.QFD role in shifting TQC from process oriented QA to design oriented QA.Include design, marketing, strategy , and knowledge management
  • 10. Conclusion :• Key tool for quality assurance•Translates customer needs into a detailedprocess/product requirements•QFD identifies the direction of improvement•QFD is dynamic tool, which needs to reviewedand verified in frequent time interval
