Explains QFD concepts clearly

2.  Introduced in Japan in 1966 by Yoji Akao.
 Quality function deployment is an approach for
implementing new design into the market.

3. Quality-Customer satisfaction .
Function-What must be done(Focus).
Deployment-How to use & develop it.

4. Customer Requirements
Company Measures
Parts design
Manufacturing Process
Production Requirements
(Day to Day Operations)

5. Product planning
Part deployment
Process planning
Process control

6.  Product planning also called ‘The House of Quality’.
 Customer
1.Expectations &
2. Needs.

7.  Led by engineering department.
 Manufacturing parts to be designed according to
the new process.

8.  Manufacturing process is documented.
 Manufacturing using engineering tools

10.  Performance indicators.
 Decisions are made to prevent failures.
 Maintenance schedules

12.  An initial step in launching QFD.
 The HOQ leads to 4Ps processes.
 A tool for comparing existing and potential designs.

14. 1. List Customer Requirements .
2. List Technical Descriptors.
3. Develop a Relationship Matrix.
4. Develop the Interrelationship Matrix
5. Competitive Assessment
6. Develop Prioritized Customer Requirements
7. Develop Prioritized Technical Descriptors

15. Problem-Needs were not adequately understood.
Solution - Voice of the customer
Will list customer requirements and expectations
•Primary factors – broad
•Secondary factors - narrow

16.  "Voice of the Engineer“
 Attributes to be benchmarked against the
competition.

17. › Identifies the strength of relationship between
customer requirements and technical
descriptors
 +9 Strong (●)
 +3 Medium (○)
 +1 Weak (Δ)
 0 Not Applicable (Nothing)

18. Interrelationship Matrix
› Identify areas in your process where technical
issues may conflict or be tough.
 +9 Strong Positive (●)
 +3 Positive (○)
 -3 Negative (x)
 -9 Strong Negative (*)

19. › Customer requirements on a scale of 1 to 5 (1
worst – 5 best)
› Technical descriptors on a scale of 1 to 5 (1
worst – 5 best)
› Finally rankings are compared to competitors by
meeting customer requirements and technical
descriptors on a scale of 1 to 5.

20. Develop Prioritized Customer Requirements
Technical Analysis of competitor
products.
› Can Identify:
 Importance of a customer requirement (1 to
10)
 Target Value – where the company wants to
be (1 to 5)
 Scale-up factor – how many points are
necessary to meet the target value

21. Develop Prioritized Technical
Descriptors
› Can identify:
 Degree of difficulty of a technical descriptor
(1 to 10)
 Target value – where the company wants to
be (1 to 5)

24.  Prioritizes what to work on and why.
 Competitive advantage world.
