    Quality Function Deployment (QFD) is a methodology used to translate customer requirements into the appropriate technical requirements for each stage of product design, engineering, and manufacturing. It is a team-based approach that involves capturing customer needs and using them to guide product development. The key steps in QFD include identifying customer requirements and technical descriptors, developing relationship matrices between what customers want and how it can be achieved technically, assessing competitors, and prioritizing customer and technical requirements based on calculated weights. An example case study demonstrates how QFD was used by a bicycle component manufacturer to design an optimal aluminum die cast handlebar stem that best meets customer needs.

    Quality Function Deployment (QFD)

    Mohan Khond
    Mechanical Engineering Department
    College of Engineering , Pune
    Learning Objectives

     The basic aim of presentation is to describe


    the methodology of QFD.
     Various Steps associated in QFD and the
    development of interrelationship matrix.
     Application of QFD with suitable illustration
    and case study .
    Why QFD?

     Survival in world class competition


     Retaining and enhancing market share
     Shorter product development cycle
     Customer awareness
    Quality Function Deployment

     Quality function deployment is literal translation of the


    Japanese words HIN SHIT SU KINO TENKAI

     The concept of QFD was introduced in Japan by YOJI


    AKAO in 1986

     The QFD methodology was developed at Mitsubishi’s Kobe


    Shipyard
     Quality-Quality is what the customer says it is.(A. Feigenboum)
     Function-In this case it is aim, purpose, operation,or action
     Deployment - The meaning of deployment is to operationalised or to
    bring out
     QFD defined as a series of translations from customer needs
    to product characteristics and ultimately to manufacturing
    procedures.

     Quality function Deployment is a team-based management


    tool in which customer expectation are used to drive the
    product development process
     It is disciplined approach to product design, engineering, and
    production and to provide in depth evaluation of product.

     Customer needs are operationalised as production process


    instruction that will produce outputs with desired characteristics.

     This method has been described as set of planning and


    communication routines that facilitate cooperation between
    marketing, design, and manufacturing during design process
    .
    Characteristics of QFD

     Qualitative technique.
     Use of Interdisciplinary team.
     Uncovering new problems and facts .
     Customer driven
    Steps in QFD
     List Customer Requirements. (WHATs)
     List Technical Descriptors. (HOWs)
     Develop an relationship matrix between WHATs and
    HOWs
     Develop an Interrelationship matrix between HOWs
     Competitive Assessment
     Develop Prioritized Customer Requirement
     Develop Prioritized Technical Descriptors
     Calculation of Absolute and Relative Weight.
    Fig-1 House of Quality
    Case study

     A company that manufactures bicycle


    components such as cranks, hub, rims, etc,
    wants to expands their product line by also
    producing handlebar stems for mountain
    bikes.
    Adding relationship Matrix to the House of Quality
    Interrelationship Between Technical Descriptors
    Adding prioritized customer requirement
    Calculation

     For column :Absolute weight = (Important to customer)


    (scale-up factor) (sales point)
     Absolute weight is product of Column in the relationship
    matrix and importance to customer e.g.
     For Aluminum(9x8+ 1x5+ 9x5+ 9x2+ 9x7+ 3x5+ 3x3)=227
     Relative weight is determined by taking the dot product of
    column in relationship matrix and column for absolute
    weight in prioritized customer requirement
     For die casting (3x16+ 9x8+ 9x5+ 3x2+ 0x18+ 3x5+
    9x3)=213
    Conclusion

     It is based on the calculation of absolute


    weight for technical descriptor and relative
    weight for technical descriptor
     Greater value of absolute weight indicate that
    handle bar Aluminum die casting
     .The relative weight also indicate that handle
    bar stem should be Aluminum die casting .
    Benefits of QFD

     An orderly way of obtaining information and


    presenting it.
     Shorter product development cycle.
     Considerably reduced start up cost
     Fewer engineering changes.
     Consensus decision
     Preserve every thing in writing .
     Develop an environment of team work.
