Methods and Techniques to Improve the Design of Cell Phones Using Quality Fun...Prathamesh Mohite
With the advancement of technology the world is becoming increasingly interconnected, both
economically and socially. Over the years there has been a significant increase in the percentage of people
accessing the internet and using a mobile phone. The quality of mobile services and the smartphones is
ultimately judged on the basis of one key factor that is, customer satisfaction. This is particularly true in case of
third or fourth generation connectivity. For this purpose we make use of QFD to acquire and analyse the
voice of customer (VOC) and then transform it into product requirements and quality assurance measures
throughout the design, build, test, commercialisation and even product retirement process. In this paper we
have presented an example to illustrate the use of QFD in the process of designing a smartphone based on
customer reviews and their requirements.

Quality Function Deployment (QFD) is a systematic approach to product development introduced in Japan in 1966. It involves translating customer requirements into technical requirements and prioritizing them to ensure customer satisfaction. Key aspects of QFD include identifying customer needs, technical responses, relationships between them, and prioritizing both to meet customer demands through product design, manufacturing, and marketing. The methodology uses a matrix called a "House of Quality" to relate customer requirements to technical responses. QFD aims to ensure products are developed according to customer needs to improve quality and reduce costs.
In today's highly competitive market environment, products that fully respond to customer expectations must be designed for survival and growth of the company. Therefore, defining and analyzing customer expectations is an important issue. In recent years, one of the most commonly used and effective methods for resolving the issue is Quality Function Deployment (QFD). As a customer-oriented approach that reflects consumer expectations, QFD provides the planning/improvement of the process by taking advantage of this information. In this study, the QFD method was used to identify and analyze the expectations of students enrolled in a language school. First, data related to student expectations were received. House of quality was established and evaluated, and as a result of the study, managers were informed that the teaching techniques practised by the teachers and equipment of the school should be developed by adopting a new trend.

Quality Function Deployment
In a few words: The voice of the customer translated into the voice of the engineer.
To design a product well, a design teams needs to know what it is
they are designing, and what the end-users will expect from it.
Quality Function Deployment is a systematic approach to design
based on a close awareness of customer desires, coupled with the
integration of corporate functional groups. It consists in
translating customer desires (for example, the ease of writing for
a pen) into design characteristics (pen ink viscosity, pressure on
ball-point) for each stage of the product development (Rosenthal,
1992).
Ultimately the goal of QFD is to translate
often subjective quality criteria into objective
ones that can be quantified and measured and
which can then be used to design and
manufacture the product. It is a complimentary
method for determining how and where
priorities are to be assigned in product
development. The intent is to employ
objective procedures in increasing detail
throughout the development of the product.
(Reilly, 1999)
Quality Function Deployment was developed
by Yoji Akao in Japan in 1966. By 1972 the
power of the approach had been well
demonstrated at the Mitsubishi Heavy
Industries Kobe Shipyard (Sullivan, 1986) and
in 1978 the first book on the subject was
published in Japanese and then later translated
into English in 1994 (Mizuno and Akao,
1994).
In Akao’s words, QFD "is a method for developing a design quality aimed at satisfying the
consumer and then translating the consumer's demand into design targets and major quality
assurance points to be used throughout the production phase. ... [QFD] is a way to assure the
design quality while the product is still in the design stage." As a very important side benefit he
points out that, when appropriately applied, QFD has demonstrated the reduction of development
time by one-half to one-third. (Akao, 1990)
The 3 main goals in implementing QFD are:
1. Prioritize spoken and unspoken customer wants and needs.
2. Translate these needs into technical characteristics and specifications.
3. Build and deliver a quality product or service by focusing everybody toward customer
satisfaction.

Challenges to implementing QFD include the time and effort required, as well as difficulties working in teams and gaining management support. An example case study on using QFD to develop a new tape product is also referenced.
Quality Function Deployment (QFD) is a systematic method to define customer requirements and translate them into design requirements, technical requirements, and part characteristics to ensure quality. It involves a team that captures customer needs, prioritizes them, and ensures the final product meets those needs. The key steps are: 1) identifying customer requirements, 2) determining technical requirements to meet those needs, 3) assessing relationships between customer and technical requirements, and 4) prioritizing customer needs to guide design. QFD aims to focus the organization on the customer and ensure customer satisfaction through the entire development process.
An Application of Green Quality Function Deployment to Designing an Air Condi...IJERA Editor
The paper tackles a systematic and operational approach to Green Quality Function Deployment (GQFD), a customer oriented survey based quality management system with regular improvement in product development. GQFD shows balance between product development and environmental protection. GQFD is not used to determine their attributes and their levels. GQFD captures what product developers “think” would best satisfy customer needs considering Environmental factor. This research used Air Conditioner as a case study for implementation of GQFD. In the design of a new Air Conditioner, apply GQFD to find out the most important parameter and functions from customer point of view and then find out Technical Characteristics. These important parameters are then put into house of quality and make relation matrix between voice of customer and Technical Characteristics. From the result of QFD applied to Air Conditioner are short out the parameter which are require modification according to voice of customer and the result has used for new design.
Quality Function Deployment (QFD) is a systematic approach to design that focuses on customer needs. It involves translating customer requirements into technical specifications across each stage of product development. The QFD process involves building a House of Quality matrix to prioritize customer needs, technical attributes, and their relationships. It then translates the voice of the customer through subsequent phases of product design, process planning, and production control. Implementing QFD alongside Lean Six Sigma aims to reduce waste and variability to improve quality, efficiency and meet customer requirements.

Quality Function Deployment (QFD) is a technique for translating customer requirements into technical requirements. It was developed in Japan in the 1960s. QFD uses a structured approach called the "House of Quality" to define customer needs and engineer corresponding technical requirements. The House of Quality consists of customer requirements, technical requirements, relationship matrices, target values, and competitor evaluation. Implementing QFD improves customer satisfaction, reduces development time and costs, and promotes teamwork and documentation.

A Novel Method for Prevention of Bandwidth Distributed Denial of Service AttacksIJERD Editor
Distributed Denial of Service (DDoS) Attacks became a massive threat to the Internet. Traditional
Architecture of internet is vulnerable to the attacks like DDoS. Attacker primarily acquire his army of Zombies,
then that army will be instructed by the Attacker that when to start an attack and on whom the attack should be
done. In this paper, different techniques which are used to perform DDoS Attacks, Tools that were used to
perform Attacks and Countermeasures in order to detect the attackers and eliminate the Bandwidth Distributed
Denial of Service attacks (B-DDoS) are reviewed. DDoS Attacks were done by using various Flooding
techniques which are used in DDoS attack.
The main purpose of this paper is to design an architecture which can reduce the Bandwidth
Distributed Denial of service Attack and make the victim site or server available for the normal users by
eliminating the zombie machines. Our Primary focus of this paper is to dispute how normal machines are
turning into zombies (Bots), how attack is been initiated, DDoS attack procedure and how an organization can
save their server from being a DDoS victim. In order to present this we implemented a simulated environment
with Cisco switches, Routers, Firewall, some virtual machines and some Attack tools to display a real DDoS
attack. By using Time scheduling, Resource Limiting, System log, Access Control List and some Modular
policy Framework we stopped the attack and identified the Attacker (Bot) machines
Hearing loss is one of the most common human impairments. It is estimated that by year 2015 more
than 700 million people will suffer mild deafness. Most can be helped by hearing aid devices depending on the
severity of their hearing loss. This paper describes the implementation and characterization details of a dual
channel transmitter front end (TFE) for digital hearing aid (DHA) applications that use novel micro
electromechanical- systems (MEMS) audio transducers and ultra-low power-scalable analog-to-digital
converters (ADCs), which enable a very-low form factor, energy-efficient implementation for next-generation
DHA. The contribution of the design is the implementation of the dual channel MEMS microphones and powerscalable
ADC system.
Influence of tensile behaviour of slab on the structural Behaviour of shear c...IJERD Editor
-A composite beam is composed of a steel beam and a slab connected by means of shear connectors
like studs installed on the top flange of the steel beam to form a structure behaving monolithically. This study
analyzes the effects of the tensile behavior of the slab on the structural behavior of the shear connection like slip
stiffness and maximum shear force in composite beams subjected to hogging moment. The results show that the
shear studs located in the crack-concentration zones due to large hogging moments sustain significantly smaller
shear force and slip stiffness than the other zones. Moreover, the reduction of the slip stiffness in the shear
connection appears also to be closely related to the change in the tensile strain of rebar according to the increase
of the load. Further experimental and analytical studies shall be conducted considering variables such as the
reinforcement ratio and the arrangement of shear connectors to achieve efficient design of the shear connection
in composite beams subjected to hogging moment.
Gold prospecting using Remote Sensing ‘A case study of Sudan’IJERD Editor
Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first
place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian
crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS
includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia.
Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra
oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in
association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation
have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they
originate as sea floor massive sulphide deposits.
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with
inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and was a major
source of wealth for the Pharaohs of ancient Egypt. The Pharaohs old workings have been periodically
rediscovered through time. Recent endeavours by the Geological Research Authority of Sudan led to the
discovery of a score of occurrences with gold and massive sulphide mineralizations. In the nineties of the
previous century the Geological Research Authority of Sudan (GRAS) in cooperation with BRGM utilized
satellite data of Landsat TM using spectral ratio technique to map possible mineralized zones in the Red Sea
Hills of Sudan. The outcome of the study mapped a gossan type gold mineralization. Band ratio technique was
applied to Arbaat area and a signature of alteration zone was detected. The alteration zones are commonly
associated with mineralization. The alteration zones are commonly associated with mineralization. A filed check
confirmed the existence of stock work of gold bearing quartz in the alteration zone. Another type of gold
mineralization that was discovered using remote sensing is the gold associated with metachert in the Atmur
Desert.
Reducing Corrosion Rate by Welding DesignIJERD Editor
This document summarizes a study on reducing corrosion rates in steel through welding design. The researchers tested different welding groove designs (X, V, 1/2X, 1/2V) and preheating temperatures (400°C, 500°C, 600°C) on ferritic malleable iron samples. Testing found that X and V groove designs with 500°C and 600°C preheating had corrosion rates of 0.5-0.69% weight loss after 14 days, compared to 0.57-0.76% for 400°C preheating. Higher preheating reduced residual stresses which decreased corrosion. Residual stresses were 1.7 MPa for optimal X groove and 600°C

Active Power Exchange in Distributed Power-Flow Controller (DPFC) At Third Ha...IJERD Editor
This paper presents a component within the flexible ac-transmission system (FACTS) family, called
distributed power-flow controller (DPFC). The DPFC is derived from the unified power-flow controller (UPFC)
with an eliminated common dc link. The DPFC has the same control capabilities as the UPFC, which comprise
the adjustment of the line impedance, the transmission angle, and the bus voltage. The active power exchange
between the shunt and series converters, which is through the common dc link in the UPFC, is now through the
transmission lines at the third-harmonic frequency. DPFC multiple small-size single-phase converters which
reduces the cost of equipment, no voltage isolation between phases, increases redundancy and there by
reliability increases. The principle and analysis of the DPFC are presented in this paper and the corresponding
simulation results that are carried out on a scaled prototype are also shown.
Mitigation of Voltage Sag/Swell with Fuzzy Control Reduced Rating DVRIJERD Editor
Power quality has been an issue that is becoming increasingly pivotal in industrial electricity
consumers point of view in recent times. Modern industries employ Sensitive power electronic equipments,
control devices and non-linear loads as part of automated processes to increase energy efficiency and
productivity. Voltage disturbances are the most common power quality problem due to this the use of a large
numbers of sophisticated and sensitive electronic equipment in industrial systems is increased. This paper
discusses the design and simulation of dynamic voltage restorer for improvement of power quality and
reduce the harmonics distortion of sensitive loads. Power quality problem is occurring at non-standard
voltage, current and frequency. Electronic devices are very sensitive loads. In power system voltage sag,
swell, flicker and harmonics are some of the problem to the sensitive load. The compensation capability
of a DVR depends primarily on the maximum voltage injection ability and the amount of stored
energy available within the restorer. This device is connected in series with the distribution feeder at
medium voltage. A fuzzy logic control is used to produce the gate pulses for control circuit of DVR and the
circuit is simulated by using MATLAB/SIMULINK software.
Study on the Fused Deposition Modelling In Additive ManufacturingIJERD Editor
Additive manufacturing process, also popularly known as 3-D printing, is a process where a product
is created in a succession of layers. It is based on a novel materials incremental manufacturing philosophy.
Unlike conventional manufacturing processes where material is removed from a given work price to derive the
final shape of a product, 3-D printing develops the product from scratch thus obviating the necessity to cut away
materials. This prevents wastage of raw materials. Commonly used raw materials for the process are ABS
plastic, PLA and nylon. Recently the use of gold, bronze and wood has also been implemented. The complexity
factor of this process is 0% as in any object of any shape and size can be manufactured.

Application of Buckley-Leverett Equation in Modeling the Radius of Invasion i...IJERD Editor
A thorough review of existing literature indicates that the Buckley-Leverett equation only analyzes
waterflood practices directly without any adjustments on real reservoir scenarios. By doing so, quite a number
of errors are introduced into these analyses. Also, for most waterflood scenarios, a radial investigation is more
appropriate than a simplified linear system. This study investigates the adoption of the Buckley-Leverett
equation to estimate the radius invasion of the displacing fluid during waterflooding. The model is also adopted
for a Microbial flood and a comparative analysis is conducted for both waterflooding and microbial flooding.
Results shown from the analysis doesn’t only records a success in determining the radial distance of the leading
edge of water during the flooding process, but also gives a clearer understanding of the applicability of
microbes to enhance oil production through in-situ production of bio-products like bio surfactans, biogenic
gases, bio acids etc.
Gesture Gaming on the World Wide Web Using an Ordinary Web CameraIJERD Editor
- Gesture gaming is a method by which users having a laptop/pc/x-box play games using natural or
bodily gestures. This paper presents a way of playing free flash games on the internet using an ordinary webcam
with the help of open source technologies. Emphasis in human activity recognition is given on the pose
estimation and the consistency in the pose of the player. These are estimated with the help of an ordinary web
camera having different resolutions from VGA to 20mps. Our work involved giving a 10 second documentary to
the user on how to play a particular game using gestures and what are the various kinds of gestures that can be
performed in front of the system. The initial inputs of the RGB values for the gesture component is obtained by
instructing the user to place his component in a red box in about 10 seconds after the short documentary before
the game is finished. Later the system opens the concerned game on the internet on popular flash game sites like
miniclip, games arcade, GameStop etc and loads the game clicking at various places and brings the state to a
place where the user is to perform only gestures to start playing the game. At any point of time the user can call
off the game by hitting the esc key and the program will release all of the controls and return to the desktop. It
was noted that the results obtained using an ordinary webcam matched that of the Kinect and the users could
relive the gaming experience of the free flash games on the net. Therefore effective in game advertising could
also be achieved thus resulting in a disruptive growth to the advertising firms.

Simple Sequence Repeats (SSR), also known as Microsatellites, have been extensively used as
molecular markers due to their abundance and high degree of polymorphism. The nucleotide sequences of
polymorphic forms of the same gene should be 99.9% identical. So, Microsatellites extraction from the Gene is
crucial. However, Microsatellites repeat count is compared, if they differ largely, he has some disorder. The Y
chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males
have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and
development. Several Microsatellite Extractors exist and they fail to extract microsatellites on large data sets of
giga bytes and tera bytes in size. The proposed tool “MS-Extractor: An Innovative Approach to extract

Importance of Measurements in Smart GridIJERD Editor
- The need to get reliable supply, independence from fossil fuels, and capability to provide clean
energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The
development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have
new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era
of smart future grid will lead to major changes in existing technologies at generation, transmission and
distribution levels. The incorporation of renewable energy resources and distribution generators in the existing
grid will increase the complexity, optimization problems and instability of the system. This will lead to a
paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and
reliable electricity supply of power. The monitoring of the grid system state and stability relies on the
availability of reliable measurement of data. In this paper the measurement areas that highlight new
measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be
monitored for improving the reliability of power systems has been discussed.

Abstract: - This work presents a proposal for a conceptual model of QFD application aiming to establish the
quality parameters in steel rolling industry. To develop this model, the following stages were carried out:
literature review to identify information about QFD use, analysis of data collected in a field research and review
of data from previous interviews with QFD users. Quality function deployment is a useful customer oriented
product development process that uses a series of structured management processes to translate the customer
needs into various stages of product planning, design, engineering, and manufacturing. The proposed method is
aimed at expanding the current research scope from the product planning phase to the part deployment phase to
provide product developers with more valuable information. Both customer requirements and the company’s
production demands will be used as the inputs for the QFD process to enhance the completeness and accuracy of
the QFD analysis results. The purpose of this paper is to show practitioners and researchers how this process can
be used as a planning process to link customer needs and product quality characteristics with attributes,
production characteristics and measurable controls, that can reveal and trace the level of satisfaction of customer
needs in the steel rolling industry. A case study is presented to illustrate the application of the proposed method.
Keywords: - Quality Function Deployment, Product Design, Quality Control, Steel Rolling, House of Quality
I. INTRODUCTION
Quality function deployment is an important product development method, dedicated to translating
client requirements into activities to develop products. It works by linking together customer needs, product and
parts design requirements, process planning, and manufacturing specifications during product development.
Basically, it is based on the use of sequentially connected cross matrix tables in which customer needs are
transformed to product characteristics and product and process engineering parameters. The QFD starts and ends
with the customer.
Yoji Akao introduced the concept of QFD in Japon in 1966. According to Akao QFD is a method for
developing a design quality aimed at satisfying the consumer and then translating the consumer’s demand into
design targets and major quality assurance points to be used throughout the production phase (Edwin).
The Voice of Customer (Griffin & Hauser, 1993) is the main driver and will be propagated through all
subsequent downstream processes, and as a result, greater customer satisfaction is created in the end
product/service. According to a study by Griffin (1992), the two most critical factors that determine the QFD’s
successful use in providing definite strategic product development benefits are the high commitment of all team
members in all functional areas.
The advantages that would be realized through the use of QFD include a reduction in the time required
for product design as well as a reduction is those costs associated with the process. This is possible because the
design alternatives are realized much earlier in the process thus reducing the number of corrections and design
errors. Also, a higher level of clarity for decision making is gained through the use of this tool. Some of
benefits of QFD are summarized below (Bossert, 1991).
1. Customer Driven:
Focus on customer requirements
Uses competitive information effectively
Prioritizes resources
Identifies items that can be acted upon
Structures resident experience/information

3. Promotes Teamwork:

Identifies actions at interfaces
Creates global view out of details
II. METHODOLOGY
The success of a product or service largely depends on how they meet the customers' needs and
expectations. Consequently, more effort is involved in getting the information necessary for determining what
the customer truly wants. The organization’s task is to form the strategies of the definitions of the customer’s
priorities and the measurement of their satisfaction based on the quality criterion. This form of activity is
connected with designing and manufacturing of product, which marks corresponding optimum level of quality
determined by customers.
The House of Quality is the first of many matrices in the QFD process of translating customer needs
into product requirements and system specifications. The number of matrices corresponds to the number of
phases in the development process. For example, the American Supplier Institute (ASI) follows a four-phase
approach, in which a QFD team deploys customer requirements into product characteristics, product
characteristics into part characteristics, part characteristics into process characteristics, and finally process
characteristics into production characteristics. Other approaches may include more phases, from customer
requirements to design requirements, engineering design, product characteristics, manufacturing/ purchasing
operations, and finally production/ quality controls.
The QFD matrix presents these issues in an outline form, which permits the organization to examine
the information in a multidimensional manner. This will serve as a basis for developing an understanding of the
QFD process in steel rolling industry other manufacturing industries.
The most-used QFD methodology beyond the HoQ is the conventional manufacturing-based QFD,
which is deployed through a four-phased sequence (Sullivan 1986). The four phases are:
• Phase I: Product planning (HoQ)
• Phase II: Design deployment (part deployment)
• Phase III: Manufacturing planning (process planning)
• Phase IV: Production planning (production operations planning)
Proponents of this design process generally build a house of quality in step to understand the
interrelation ship between the customer req. and design parameter. The overall process of QFD is based on its
core matrix framework, called the HoQ. The components of this house are:
Understanding and identifying the target customers
Identifying customer requirements (WHATs)
Establishing relative importance of customer requirements
Analyzing the customer requirements (WHATs)
Performing a customer competitive evaluation and analysis
Identifying service characteristics (HOWs)
Establishing relationships between the WHATs and HOWs
Prioritizing service characteristics and technical weightings
Establishing the correlations matrix
Performing a technical competitive assessment
Setting desired target values to achieve customer satisfaction
III. QFD IMPLEMENTATION
A. Customer Voices
In the collection of customer voice we have taken interviews of customers and retailers. As the
consumers are well known and familiar with the product so it was better to do the survey among end users.
Supporting techniques in developing a Core QFD matrix included brainstorming, focus group discussions,
questionnaires, and interviews. These methods allowed developing and organizing information through a
structured process and providing visualization of relationships at various detail levels. The customer voices are;

Edge of product is not good
Shape is not uniform
Surface quality is not better
Corrosion problem
Acceptance of Product
B. Translation of Customer Voices into Technical Parameters
In the voice collection it is apparent that customers’ voices follow no order. Customers do not deliver
their comments in an organized manner. The first comment concerns the quality of edge, the second concerns
the geometry of shape, and the next states the quality of surface, fourth voice concerns weather protection, the
fifth voice concerns preferences of product.
Table I: Translation of Customer voices
1 Edge of product is not good Quality of Edge
2 Shape is not uniform Geometry Shape
3 Surface quality is not better Quality of Surface
4 Corrosion problem Weather Condition Protection
5 Customer Acceptance Acceptance of Product
The beginning of technical portion of the matrix is the translation of the customer’s voices into
technical requirements. The voices must be translated into the type of language that the company uses to
describe its products for design, processing, and manufactures at the same time.

2 Geometry Shape Control of charge
3 Quality of Surface Heat treatment
4 Weather Condition Protection Roll levelling
5 Acceptance of Product Corrosion protection
C. Customer Competitive Analysis
The customer evaluation of the performance of the competitors’ products of the surveying company
was determined using a scale of 1 to 5. In this case two competitors were examined for comparing and
benchmarking process. The customer competitive analysis shows that where the consumer product is today, and
what the competitors are doing with respect to the customer demands

D. QFD Metrix
It is helpful to record decisions about each technical requirement to show the direction that customers
prefer. For every technical requirement, there is a direction that is most favourable for customers, one that will
maximize their satisfaction. This information can be helpful to team when they are examining the co-
relationship between technical requirements and when they are establishing targets. The symbols showing
direction of customer improvement are usually placed in the matrix above the technical requirements. They have
their greatest value when examining the co relationships between technical requirements. When they are placed
across the top of the matrix, they are conveniently located during co-relationship determination

across the top of the matrix, they are conveniently located during co-relationship determination.
The customer’s evaluation of poor performance of all companies is strong signal that a competitive
opportunity exists. Any other companies doing similar customer research will see this same situation and the
obvious opportunity. Our chief competitors are at higher positions, so we have to improve our product to best
satisfy our customers The portion of the QFD planning matrix reserved for the results for competitive technical
testing can be used in a variety of ways depending upon a team’s determination. The competitive assessment
data shown in diagram can be transferred to the matrix as a series of numerical data. An alternative is to portray
the data graphically another approach is to show both the data and the graphic portrayal. Observation indicates
that most people find the graphic representation easiest to use when analysing the completed matrix to establish
priorities and competitive targets.
C. Establishing targets
If the team combines its discussion of target values and graphic plots, the concern for how to plot the
data will normally resolve itself. The next figures will help illustrate this process each represents a selected
piece of the QFD product planning matrix. Each shows the customer voice, importance, complaints, and
competitive evaluation along with the technical competitive assessment data and the strength of relationship.
Each uses the technical requirement different customer competitive evaluations and different competitive test
assessment data are used in each figure to help illustrate the team decision process [4].

D. Analysis
House of Quality for hot rolled steel has been presented (Figure 3).
The building of The House of Quality covered the following phases:
Phase I: The demands and desires of customer have been established.
Phase II: The importance of demands of customer has been classified. And also the priorities of the individual
customer requirements have been established.
Phase III: The scale of the importance of own activity at customer with his requirements has been compared.
Phase IV: Fulfilled demands of customer have been assigned to corresponding parameters of product. Answers
to question have been established – What does customer expect? And how will it be realized by product?
Phase V to VII: Measurable (standard) values of parameters, the possibilities of achieving the aim, difficulties in
technical realization have been defined.
Phase VIII: The dependence field between phase I and phase II.
Phase IX: Comparison between company’s product and competition products – based on customer’s estimation.
Phase X: The analysis of estimation achieved by customer.
Phase XI: Comparison between company’s product and competition products – based on technical parameters.
Phase XII: The mutual dependence field between technical parameters of hot rolled steel.
Phase XIII :The critical points of sales.
Fig. 5 shows that customer voice “Quality of edge” is at 2.5 and the chief competitor is at 3.5 and the
importance of this voice is 2.4, there are no complaints for this voice.
For the customer voice “Geometry shape”, the importance rating for this voice is 1.7 and on 1-5 scales our
company is at 2 and the chief competitor is at 5. There is one complaint regarding this voice.
For the customer voice “Quality of surface”, the importance rating for this voice is 3.3 and on 1-5 scales our
company is at 2.5 and the chief competitor is at 4. There are 2 complaints regarding this voice.
For the customer voice “Acceptance of product”, the importance rating for this voice is 1.2 and on 1-5
scales our company is at 4 and the chief competitor is at 5. There is no complaint regarding this voice.
The weight can be calculated for each column that represents a combination of both customers’ level of
importance the strength of the relationships. This is accomplished using the product of the relationship strength
and the importance. Thus, in column 1, row 1 in figure 5 the customer importance level is 3.6 and the weight for
the strong relationship symbol is 9; the column weight is 28.3.
Similarly, figure 5 shows column weight for column 2 is 4.5, for column 3 is 7.4, for column 4 is 22.2, for
column 5 is 61.2. These are recorded across the bottom of the matrix.
