Method of better understanding the customer needs and relating them to the PDS
•
QFD was developed to bring a personal interface to modern manufacturing and business
•
QFD links the needs of the customer (end user) with design, development, engineering,
manufacturing, and service functions
•
Understanding customer needs
○
What 'value' means to the customer
○
Understanding how customers or end users become interested, choose, and are
satisfied
○
Analyzing how we know the needs of the customer
○
Deciding what features to include
○
Determining what level of performance to deliver
○
Intelligently linking the needs of the customer with design, development, engineering,
manufacturing, and service functions
○
QFD provides a comprehensive development process for:
•
Should be employed at the beginning of every project (original or redesign)
•
Customer requirements should be translated into measurable design targets
•
It can be applied to the entire problem or any subproblem
•
First worry about what needs to be designed then how
•
It takes time to complete, but pays off later in the design process
•
Also known as House of Quality

○
Listen to the voice of the customer first: need to identify the customer
○
Consumer
▪
Regulatory agencies
▪
Manufacturing
▪
Marketing/Sales
▪
In most cases, there is more than one customer
○
Customers drive the development of the product, not the designer
○
What do the customers need and want?
○
○
Need to determine what is to be designed
○
List all the demanded qualities at the same level of abstraction
○
Product works as it should
