Problem Statement:

To Perform a QFD analysis for the product:Blue Ray CD-Player: Group 8

Quality Function Deployment (QFD):

Quality Function Deployment (QFD) is a systematic and a critical approach to design

based on a close awareness of customer needs and expectations. These needs will be

translated into technical characteristics: Design, Verification, and Production. Ultimately,

these technical characteristics will be utilized to highlight customer needs.

Technically, QFD mainly is implemented to improve the customer communication,

specification that correlated to customers’ needs to determine and allocate the resources

accurately. The completions of the QFD analysis will be presented throughout the House

of Quality.

House of Quality:

The QFD analysis for this project will be performed on the Blue Ray CD-

Player. The house of quality will be used to gauge specifically to

identify the relationship assessment for each customer needs vs. each

requirements level.

Product Planning Phase:

On this phase, the house of quality will be utilized after gathering the

customers’ needs and expectations to be translated into specified

technical characteristics. The product planning phase has ten Tasks

which will be on the following:

Task 1: Identify Customer Needs:The following criteria are mostly suit the customer needs for a Blue Ray CD-Player:

1. Price2. Portable (Dimension & Weight)3. Reliability4. Wi-Fi Connection(also browser to surf Apps:Netflix,Pandora) 5. Auto Power Off Feature6. Able to Convert 2D to 3D.7. Motion Control Remote8. Bookmarking and Resume: A Feature to bookmark a

specific scene, option available for multiple discs, Resume: A Feature to resume the disc where it is stopped, option available to multiple discs.

9. Multiple Disc Capacity10. DLNA ( Digital Living Network Alliance) 11. Customer Service & warranty.

Task 2: Determine CustomerDesirability:

8. Bookmarking and Resume 39. Multiple Disc Capacity 310. DLNA 3

11. Customer Service and warranty 3

Task 3: Evaluate the Competitive Performance of Major Competitors:

The following are the ratings of customer satisfaction for each competitor’s product on a scale of 1-5:

Ratings of Customer Satisfaction

5 Completely Satisfied

4 Very Satisfied3 Fairly Well

Satisfied2 Somewhat

Satisfied1 Very

dissatisfied

Blu-ray players are at the top of the pyramid when it comes to home Entertaining equipment. We had analyzed by far more entertainment options, on better picture and sound quality and overall the ability to have the ultimate movie experience by three different products A.)LG BP series B.) Panasonic BDP series and C.)Sony BDP series.

Therefore, the following are the ratings of customer satisfaction for each competitor’s product:

Task 4: List the Technical Characteristics:

The listed technical characteristics of a Blue Ray CD-Player have been chosen

based on the technical components that can be measurable and controllable

and directly affect the customer needs. The technical characteristicsof Blue

Ray CD-Player are as follows:

1. Have Playback Capability of playing (DVD-ROM/DVD±R/DVD±RW, Audio CD/CD-R/CD-RW, USB Playback, and External HDD Playback).

2. Video Support Format (Support MPEG-1, 3GP, M4V, WMV, FLV).3. Audio Support Format (Dolby Digital, Dolby Digital Plus, Dolby True HD, DTS,

MPEG 1/2 L2, MP3 etc.)4. Enhanced Video Features (1080p Up scaling, Noise Reduction, Deep Color,

Video Enhancement)

5. Enhanced Audio Features (DD 2ch Down Mix, LPCM Conversion (DTS HD/Dolby TrueHD, Dynamic Range Control)

6. Set Up Wizard7. AV Inputs/Outputs HDMI out, Digital Audio Out,USB 2.08. Record (HDTV) without any losing of quality.9. Operate with AC 120 V/ 60 HZ.10. Update System Software automatically.11. Sounds Adjustability.12. Memory Card & USB Connection.13. Uniphier Chip Processor14. Picture Adjustability.

Task 5: Identify Relationships between Customer Needs and Technical

Characteristics:

The following rating can shape the level of the relationship between

customer needs and technical characteristics on a scale of 1-9 and the levels

of the relationship are on the following table:

Levels of Relationship

9 Strong Related3 Medium Related1 Weak Relation

The following table gives the levels of the relationship between customer needs and technical characteristics of a Blue Ray CD-Player:

Levels of Relationship – Blue Ray CD-Player

Task 6: Develop Correlations between Technical Characteristics:

The technical characteristics can have a positive or negative correlation, and

the QFD will be in the top on the quality house, and the levels of correlation

on the following table:

Levels of Correlation

++ Strong Positive Correlation+ Positive Correlation- Negative Correlation-- Strong Negative

Correlation

Task 7: Determine the Direction of Improvement:

Each technical characteristic will be determined for the direction of improvement. There are

three types of characteristics on the following table:

Direction of Improvement

↑ Larger the Bettero Nominal the Best↓ Smaller the Better

The following are the direction of improvement of technical characteristics for a Blue Ray CD-

Player:

Direction of Improvement – Blue Ray CD-Player

Task 8: Calculate ratings of technical Importance:

The ratings of the technical importance for a Blue Ray CD-Player are as follows:

Ratings of Technical Importance – Blue Ray CD-Player

Task 9: Perform Technical Competitive Benchmarking:

The measurement usually correlates directly and strongly with the competitive performance

ratings of the products.

The Technical Competitive benchmarking values for the competitors’ products are on the following table:

Technical Competitive Benchmarking – Blue Ray CD-Player

Task 10: Determine the Technical Targets:

Each technical characteristic will be determined by measurable technical targets. Practically, these targets are utilized to assure that the customers’ needs whether they have been

accomplished and planned properly to compete in the Blue Ray CD- Player’s sales market. The technical Characteristics target values for the Player are on the following table:

The technical Characteristics target values for a Player are on the following table:

Technical Target Values – Blue Ray CD-Player
