TOTAL QUALITYQualitas adalah segala keseluruhan karakteristik dari sebuah entiti yang berdasarkan pada kemampuan barang/produk tersebut untuk memenuhi kebutuhan baik yang tersirat maupun yang tidak.

(ISO/DIS 8402-1991 )

Bergantung pada kedalaman dari lingkup aplikasinya, ISO telah menggariskan tiga standar dimana qualitas dapat dipenuhi, yaitu :

ISO 9001 : Quality system, Model for quality assurance in design/development, production, installation ad servicingISO 9002: Quality system – model for quality assurance for production, and

installationISO 9003: Quality system – model of quality assurance in final inspection and

tests.

SYSTEM DESIGN INNOVATION QUALITY FUNCTION DEPLOYMENT

Quality Function Deployment (QFD) is a systematic approach for the design of new product or services based on close awareness of customer desires coupled with integration of corporate functional groups

This approach is a set of planning and communication techniques that focus and coordinate organisational capabilities in order to develop products that most closely meet customer’s actual needs

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 8

Page 9: QUALITY BY DESIGN Quality Function Deployment

QFD can be seen in two lights :

1. As a comprehensive organisational mechanism for planning and control new product development

2. As localised techniques to translate the requirement of one functional group into the supporting requirement of a downstream functional group.

QUALITY FUNCTION DEPLOYMENT

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 9

Page 10: QUALITY BY DESIGN Quality Function Deployment

QFD requires multifunctional team of expert to participate simultaneously in a complex analytic exercise, bringing diverse perspective to bear on key issues of design

In localised usage, QFD serves both technical and organisational function

QUALITY FUNCTION DEPLOYMENT

Quality Function Deployment (QFD) is a set of planning and communication routines that focuses and coordinates skills within an organisational first to design, then to manufacture and market goods that customers want to purchase and will continue to purchase “ [Hauser&Clausing]

It aims at stimulating and structuring this multidisiplinary communication.

QFD supports a project team in identifying the needs of the custumer and interpreting them in term of technical parameters and target values Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 14

QUALITY FUNCTION DEPLOYMENT

PRODUCT ATTRIBUTES

Product attributes reflecting the wishes of the customer. The attributes should be based on the voice of the customers.

To obtain such collection of product attributes, creativity techniques can be used as well as data obtained from through market and consumer research, document of complaints and repairs, trend analysis and earlier QFD analyses.

In applying QFDfor the first time, it is adviseable to divide the step into 4 steps i.e Generate, Select, Classify, and structure

The last part, the relative importance of product attributes is compared and weighted

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 16

Page 17: QUALITY BY DESIGN Quality Function Deployment

CUSTOMER NEED ANALYSIS

• Need analysis is concerned with establishing the true needs of the customer – the ‘voice of the customer’- (VOC).

• This can be obtained by extensive examination of the views and reports of representative bodies, market data publications (buying habits), reports giving official opinions and reactions to products in use and also by structured interviews or customer questionnaires.

• The establishment of customer need is important. Ideally, needs analysis should be approached by structuring interview schedules or questionnaires around the element of the PDS.

QUALITY FUNCTION DEPLOYMENT

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 17

Page 18: QUALITY BY DESIGN Quality Function Deployment

CUSTOMER NEED ANALYSIS

• The PDS primary elements should form the triggers for asking the right questions of customers and so structured the analysis will naturally from the basis for the PDS itself

• This is to be preferred to random approaches to ascertain customer needs, which tend to leave fundamental gaps in the information gathered. This happens particularly if the questions themselves are derived and driven from consideration of existing products and customers views of those products rather than from fundamental needs issues.

QUALITY FUNCTION DEPLOYMENT

PRODUCT EVALUATION

This step, assumes that the organisation involved has a comparable product on the market for the specific target group.

Performance of the current product is submitted to an evaluation, by competitive bench-marking. The earlier obtained product attributes are used as evaluation criteria.

For each evaluation criterion it is accertained whether the product is better, similar or worse that the competitive products all this seen from the customer’s prespective.

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 19

Page 20: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

PROJECT OBJECTIVES

The evaluation provides an insight into the problems regarding the function of the current product.

Combining these performance data with relative importance of the product attributes is useful in assessing the opportunities for improvement of the product and in determining the project objectives.

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 20

Page 21: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENTENGINEERING CHARACTERISTIC

In this step, the new product is described in terms of engineering characteristic.

These characteristic here called “Technical Parameters” and the measurement of units can be based on the specifications of the forerunners of the product or can be derived by operationalisation of the product attributes

Measureability of the parameters is seen as very important.

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 21

Page 22: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

MATRIX INTERACTION

The project objectives from steps 3 are subsequently translated into priorities for the technical parameters.

This steps form the core of the QFD method as the technical parameters can be linked to various product attributes, in a matrix the product attributes (what) are set off against the technical parameter (how) Subsequently, it is determined for each cell of the matrix whether there is a relationship or not, and if so , what is the strength of this relationship.The completed matrix provides the operationalisation of the product attributes, and is tool for determining the priority of the technical parameters

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 22

Page 23: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

INTERACTION BETWEEN PARAMETERS

Changing parameters can influence one or more other parameters.

It is important to make the nature and strength of these interaction explicit before generating solution to improve one or more specific parameters of the product.

In a second matrix, the so called “the roof of the House of Quality” the interaction between the parameters can be laid down.

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 23

Page 24: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

TECHNICAL ANALYSIS AND TARGET VALUES

The current product and competitive products are being analysed to established the parameter values of various products.

This comparison provides an insight into the possibility for improvement of the product and can help to set target values to be pursued.

The inventory of possible improvement also provides a test for consistency of interaction matrix and the project objectives as it must be possible to align the results of the technical analysis through the interaction matrix with the results of product evaluation

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 24

Page 25: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

FEASIBILITY

In general, one will seek improvement of those parameters for which the competitive products score better than the own product.

The feasibility, however, of an improvement depends on the knowledge and skills of the people in the organisation, the available development capacity and the available production process.Therefore it is useful to estimate the degree of complexity or the costs of an improvement

Finally, based on the priorities, feasibility and the mutual relationship between parameters, it has to be decided on which parameter and target values in the product development project will focus

Product DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 25

Page 26: QUALITY BY DESIGN Quality Function Deployment

QUALITY FUNCTION DEPLOYMENT

DEVELOPMENT PLAN

The final results of QFD method is a development plan for the product involved.

This plan lays down the target values(requirement) for technical parameters and is tailored to the development capacity available for the project.

Parameter which because of feasibility do not yet qualify for improvement can give direction to R&D activities in the long term

3. Project Objectives:

• Determining the aspects to improve involves strategic choices for relative importance of the product attributes

• For attributes which do not need improvement, the target value is equal to the evaluation score of current product

• The improvement rate relates the desired improvement to the current performanceImprovement rate = target value/evaluation score

• Weight of each product is calculated Weight = importance x improvement rate

• Normalising the weighing scores into percentageProduct DevelopmentDr A. Riza Wahono : “ Qualitas krn Desain ” modul 5 33

• Technical trade-offs• If one technical feature is improved, is there a strong

possibility that another will also improve ? If yes then

POSITIVE correlation exists• Alternatively, If one technical feature is improved, is there

a strong possibility that another will get worse ? If yes then

NEGATIVE correlation exists• Knowing the relationship and the priority for each technical

parameter the company must approach the conflict as an

opportunity for technical breakthrough.

• On the basis of technical parameter, another comparison and

evaluation should be carried out

• On the basis of the technical data and the priorities of the

parameter the target values are now being determined

• A group of related technical parameters with these target

values can then be submitted as PDS to a relatively

independent design assignment team of designers
