3. Quality function deployment
 It is a structural approach
to define customer needs
or requirements
 QFD is a technique for
translating customer
requirements into
technical requirements.

4. Who was developed (QFD)
 It was developed in Japan by Dr.Yoji
Akao in the 1960s to transfer the
concepts of quality control from the
manufacturing process into the new
product development process.
 QFD is referred to as the “voice of the
customer,” which helps in identifying
and developing customer requirements

5. Characteristics of QFD
 4 Main Phases to QFD
 Product Planning including the ‘House of Quality’
(Requirements Engineering Life Cycle)
 Product Design (Design Life Cycle)
 Process Planning (Implementation Life Cycle)
 Process Control (Testing Life Cycle)

6. How the house of quality is made
up ?
1. WHAT
2. HOW
3. Correlation matrix (Roof)—technical requirements
4. Interrelationship matrix
5. Target value
6. Competitive evaluation.

7. How the house of quality is made
up ?
What :The WHAT is the first step in developing the house of quality.
What type of air-conditioning system is required for the building?
What type of communication system is required for the building?
What type of flooring material is required?
HOW : The project team members translate the requirements (WHAT)
into technical design characteristics (specifications) and are listed
across the columns of the matrix.

8. How the house of quality is made
up ?
 correlation matrix
The correlation matrix identifies the technical interaction or physical
relationship among the technical specifications.
interrelationship matrix
The interrelationship matrix illustrates team members’

9. How QFD Works?
 Customer-requirements-driven design and production planning
process
 Rationale is that product quality is measured by customer satisfaction.
 QFD is building requirements into products.
 Inputs customer requirements

11. Why Implement Quality Function Deployment
(QFD)
 Customer Focused.
 VOC Competitor Analysis.VOC means Voice of the Customer
 Shorter Development Time and Lower Cost.
 Structure and Documentation.

12. The QFD Team
 When an organization decides to implement QFD, the project manager
and team members need to be able to commit a significant amount of
time to it, especially in the early stages.
 There are two types of teams:
 Designing a new product
 Improving an existing product

13. Benefits of QFD
• Improves Customer Satisfaction
 Reduces Implementation Time
• Promotes Teamwork
 Provides Documentation.
 Reduced time to market
 Improved quality

15. How to Implement Quality Function Deployment
(QFD)
 Product Definition:
The product Definition Phase begins with collection of VOC and translating
the customer wants and needs.
 Product Development:
During the Product Development Phase, the critical parts and assemblies are
identified.
 Process Development:
The manufacturing and assembly processes are designed based on product
and component specifications.
 Process Quality Control:
Prior to production launch, the QFD process identifies critical part
and process characteristics

16. QFD Consulting
 Companies are continuously looking for ways to increase their market
share and gain new customers while retaining their existing customer
base.
 The customer requirements must be embedded into their product
planning, design and development processes.
 Provide the forms and templates required for your QFD process
 Evaluate the resources you currently have available for QFD
implementation and develop a plan for moving forward
