Quality Function Deployment

Friends, the topic which is very important during the product development stage and conception of a product is "Quality Function Deployment" (QFD).

In today scenario of market there are lots of options are available for a customer before buying a product as lots of market players are available, every customers wants a product which is cheap and best in quality not only this but "additional features" in the product.

So to consistently add the new additional feature in the product , the primary thing is to understand the customer needs and what they want....

To QFD is a process of product development and design to convert customer requirement  into the design requirement of a product.

Technical Definition of QFD may be:

A system for translating consumer requirement into appropriate company requirement at every stage from research through product design and development, to manufacture, distribution, installation and marketing,sales and services.

Different Phases of QFD process:

1) Product Planning
2) Part Developemement
3) Process Planning
4) Production Planning

Now when a company decides to go for the QFD, the project incharge and project team members should commit a good amount of time to it, majorly in the early stages.

One of the important tool in the QFD process is "Communication"

There may be two conditions for the QFD team formation:
a) New product development
b) Improving an existing one

 Advantages of the QFD:

- Improved quality
- Improved Profitabitability
- Incerased Customer Satisfaction
- Lower cost in design and manufacture
- reduction in design changes/problem
- Improved communication with the customer
- Improved documentation
- A more customer oriented work force

Some of the well known companies of world has been adopted the QFD, to improve their services and product Quality:

IBM computers
Du Pont chemicals
Texas Instruments
Philips International
GVC Elastomers

Constructing the House of Quality:

As QFD concentrates on the customer expectations and needs, a research has to be carried out to know the expectation of customer regarding the product under QFD process...

During the collection of the information, the QFD team must continually ask and answer numerous questions,such as-

-What does the cutomer really wants?
- What are the customers expectations?
- Are the customer's expectations used to drive the design process?
- What can the design team do so achieve customer satisfaction?

The constituents of Chart of Quality may be:
1. What customer wants
2.Rank of Customer wants (relative importance)
3. How these wants can be met out
4.Relationship between what and how
5. How much these wants can be met out
6. Targets values of customers wants
7.Interrelationship (Technical)
8.Competition from other existing product (Rating)
9.Compare with bench mark
10. Regulatory items
11.Relative importance of customer wants


At the end we can say friends that "QFD" provides a opportunity for the conversion of "What" customer wants into the real product....
