what s qual ty funct on deployment
What ıs qualıtyfunctıondeployment?

Quality Function Deployment is a quality development method which is used fornew product design or improvement of existing product and at the same time.

slide4

In order to stay in competitive market, the companies try newapproaches and put the successful ones into application.One of the widely used approaches is, today, Quality Function Deployment (QFD).

the three ma n goals n mplement ng qfd
Thethreemaıngoalsınımplementıng QFD :
  • Prioritize spoken and unspoken customer wants and needs.
  • Translate these needs into technical characteristics and specifications.
  • Build and deliver a quality product or service by focusing everybody toward customer satisfaction.

QualıtyFunctıonDeployment has helped to transform the way many companıes:
  • Plan new products
  • Design product requirements
  • Determine process characteristics
  • Control the manufacturing process
  • Document already existing product specifications
applications of quality function deployment
APPLICATIONS OF QUALITY FUNCTION DEployment

It can be used for,

  • a product,
  • a new service
  • available for a product
  • for investment planning
  • for process management
  • technology-driven engineering
  • even can be used for policy management
benefits of quality function deployment
BENEFITS OF QUALITY FUNCTION DEPLOYMENT

CustomerDeployement

The focus is on customers wants, not what the company thinks the customer wants.  The "Voice of the Customer" drives the development process.

Competitive analysis

Other products in the marketplace are examined, and the company product is rated against the competition.

Reduceddevelopmenttime

Careful attention to customer requirements reduces the risk that changes will be required late in the project life cycle.  Time is not spent developing insignificant functions and features.

Documentation

 A knowledge base is built as the QFD process is implemented.  A historical record of the decision-making process is developed.

phases of qual ty funct on deployment
Phases of qualıtyfunctıondeployment

Phase 1, Product Planning

Phase 1, or product planning, is also called The House of Quality.

Phase 2, Product Design

Product design requires creativity and innovative team ideas.

Phase 3, Process Planning:

During process planning, manufacturing processes are flowcharted and process parameters (or target values) are documented.

Phase 4, Process Control:

In this phase decisions are made as to

which process poses the most risk and controls are put in place to prevent

failures.

the house of quality
THE HOUSE OF QUALITY :

The House of Qualitytranslates customer requirements, based on marketing research and benchmarkingdata, into an appropriate number of engineering targets to be met by a new product design.

steps to the house of quality
STEPS TO THE HOUSE OF QUALITY :

THE VOICE OF THE CUSTOMER’

The initial steps in forming the House of Quality include determining, clarifying, and specifying thecustomers’ needs.

slide13

TECHNICAL REQUIREMENTS:

The next step of the QFD process is identifying what the customer wants and what must be achieved tosatisfy these wants. In addition, regulatory standards and requirements dictated by management must beidentified. Once all requirements are identified it is important to answer what must be done to the productdesign to fulfill the necessary requirements.

PLANNING MATRIX:

The planningmatrix shows the weighted importance of each requirement that the team and its competitors are attemptingto fulfill. Customer ratings, typically ranging from 1 to 5, are given to each company under eachrequirement. The customer ratings are combined with the weighted performance of each demand toproduce an overall performance measure for the companies.

slide14

INTERRELATIONSHIP MATRIX

  • The main function of the interrelationship matrix is to establish a connection between the customer’sproduct requirements and the performance measures designed to improve the product.
  • The team asks the question, "what is the strength of the relationship between the technical descriptors and the customers needs?" Relationships can either be weak, moderate, or strong and carry a numeric value of 1, 3 or 9.

TECHNICAL CORRELATION MATRİX

This room in the matrix is where the term House of Quality comes from because it makes the matrix look like a house with a roof. The correlation matrix is probably the least used room in the House of Quality; however, this room is a big help to the design engineers in the next phase of a comprehensive QFD project. Team members must examine how each of the technical descriptors impact each other. The team should document strong negativerelationships between technical descriptors and work to eliminate physical contradictions.

slide15

TECHNICAL PROPERTIES AND TARGETS:

The technical properties matrix uses specific items to record the priorities assigned to technicalrequirements. It also provides a technical performance achieved by competitive products and the degree ofdifficulty in developing each requirement.

slide16

CONCLUSION

Through customer needs and competitive analysis, the House of Quality helps to identify the criticaltechnical components that require change.

A research has beenmade in thisstudywithpeoplewhoaremostlyemployedandagedbetween 20 and 30. Consideringtheresults of theresearchthat has beenmadeforpotentialcustomers, a newhairdryerproductdesign can be based on thecustomerrequirements. Forexample, a hairdryerwhichdriesquickly is an importantfactor in thevoice of customerandnewhairdryerdesigns can be implementedwith a newapproachinstead of makingimprovements on ordinaryhairdryerdesigns.

Ina truequalitysystem, weneededtoaddress not onlythequality of theproductsbeingdesignedandproduced, but thequality of thenewproductdevelopment (NPD) processitselfthatcreatesthoseproducts. Inotherwords, not justthequality of an assembly of parts, but thequality of thehumanactivitiesneededtodesignandproducethosepartshumanactivitiessuch as productplanning, marketing, engineering, procurement, testing, manufacturing, packaging, after-salessupport, etc. Thequalityfunctionmust be deployedacrossallthecompany.

  • Inproductorprocessimprovementactivitiessuch as kaizen , sixsigma , etc. thefocus is on existingproducts in productionthat fail tomeetinternalqualitystandardsor fail in thefield. This is definitely in therealm of thequalitydepartmenttoaddress. Innewproductdevelopment (NPD), however, there is nodesign, product, manufacturingprocess, andsoforth yet, so it is unrealistictowaituntilthere is in orderforthequalitydepartmentto do itsjob.
  • InNPD, qualitymustbeginbeforedesign, whenthebusinesscase is beingdevelopedthatdefinesthescopeandfinancialdeliverables of theproject, whothekeycustomersareand how theyareto be researched, what is theprojecttimelineandwhataretheresourceandbudgetconstraints, etc.

Theonlywayquality can be assured is fororganizationfunctionstoworktogetherfromthe start.

  • Thisis what is calledcross-functionalmanagement (CFM) and it is onecornerstone of total qualitymanagement (TQM); QFD is the CFM systemforassuringnew NPD qualitybydeployingthequalityfunctionacrossthe total organization.
first example
FIRST EXAMPLE:

1.An Automobile Bumper

Customer Request:

There is too much damage to bumpers in low-speed collisions. Customer wants a better bumper.

slide33

Step 2: Determine CustomerRequirements/Constraints

  • I want something that looks nice (basic)
  • It must hold my license plate (performance)
  • I want it strong enough not to dent (excitement)
  • It must protect my tail-lights and head-lights (performance)
  • I don’t want to pay too much (basic)

Step 1:Identify Customer(s)

  • Repair Department
  • Automobile Owner
  • Manufacturing Plant
  • Sales Force
slide36

Step 4: Competition Benchmarking

  • Identify Competitors
  • Test and Analyze Competitor Products
  • Reverse Engineer Competitor Products
  • Rate Competitor Products against customer requirements/constraints

Put competitive benchmarking information into

House of Quality Chart

slide37

Requirements into Measurable Engineering Specifications and define target values

  • Specify how license plate will be held
  • Specify how to resist dents through material yield strength, young's modulus, etc.
  • Specify with a dollar amount the term ‘inexpensive’
