Product Design
• Product design – the process of defining all of the
companies product characteristics
– Product design must support product manufacturability (the ease
with which a product can be made)
– Product design defines a product’s characteristics of;
• appearance,
• materials,
• dimensions,
• tolerances, and
• performance standards

4. Service Design
 Specifies what the customer is to
experience
 Benefits to the human senses
 Psychological
benefits

5. An Effective Design Process
 Matches product/service characteristics
with customer needs
 Meets customer requirements in simplest,
most cost-effective manner
 Reduces time to market
 Minimizes revisions

6. Degree of Design Newness
1.Modification of an existing
product/service
2.Expansion of an existing product/service
3.Clone of a competitor’s product/service
4.New product/service

8. New Product Development Process
• Concept Development
• Development of Detailed Product Design&
Prototyping
• Pilot Production/Testing
• Mass Production and Commercialization
3 - 8

9. Stage I. Concept Development & Product
Planning
 This involves: Generating Ideas for the new product
New ideas can be generated from:
 Benchmarking
-Comparing product/process against best-in-class
 Reverse engineering
Dismantling competitor’s product to improve your
own product
 Market surveys , focus groups and interview are
important tools to get product ideas from customers.
 Brain storming, panel discussions , Delphi-method etc
are important tools in generating ideas from within.
3 - 9

10. Cont… Product Planning
• At this stage the following activities need to
be undertaken:
 Choosing components and interact with suppliers
;build early system prototypes ;define product
architecture
 Defining target customer’s parameters ; develop
estimates of sales and margins ; conduct early
interactions with customers ….through marketing
department
 Developing cost estimates ; define process
architecture; conduct process simulation; validate
suppliers ….through manufacturing department
 The final decision in this stage will be to approve the
product development program
3 - 10

11. Stage II. Development of Detailed Product Design&
Prototyping
 This stage requires: SPECIFYING THE DESIRED FUNCTIONAL
FEATURES OF THE PRODUCT AND THE ROCESS
• How ever the detailed product design need to be evaluated in terms of
the following criteria:
Achievement of customer requirements and product
specifications
Expected quality and reliability of the product
Reducibility and cost of the product
The impact on production of the company’s other products
3 - 11

12. Stage III: Pilot Production/Testing
This stage requires the following activities :
 Small quantity production
 Market test of the sample products
 Gathering customer opinion on the sample
products
 Based on the customer feedback making the
necessary design changes in the product
STAGE IV : Mass Production and
Commercialization
3 - 12

13. Production Design
 How the product will be made
Simplification- reducing number of parts,
assemblies, or options in a product
 Standardization - using commonly available and
interchangeable parts
 Modular Design - combining standardized
building blocks, or modules, to create unique
finished products
 Design for Manufacture (DFM) - designing a
product so that it can be produced easily and
economically

Product

17. Quality Function Deployment
• Interfunctional teams from marketing, design
engineering, and manufacturing
• Begins with listening to the customer
– Uses market research
– Customer preferences are defined and broken
down into customer requirements
 Translates voice of customer into technical design
requirements
 Displays requirements in matrix diagrams
 first matrix called “house of quality”
 series of connected houses

Quality Function Deployment
(QFD)
• Also known as “House of Quality”
• Customer Attributes (“Voice of the
Customer”)
• Engineering Characteristics (“Voice of the
Engineer”)
• Tradeoffs
• Competitors Comparison

21. Benefits of QFD
Promotes better understanding of customer
demands
Promotes better understanding of design
interactions
Involves manufacturing in design process
Provides documentation of design process

Value Analysis/Value Engineering
 Achieve equivalent or better performance at a lower
cost while maintaining all functional requirements
defined by the customer
 Does the item have any design features that are
not necessary?
 Can two or more parts be combined into one?
 How can we cut down the weight?
 Are there nonstandard parts that can be
eliminated?

23. Value Analysis/Value Engineering
(VA/VE)
• Purpose is to simplify products and processes
• Objective is to achieve better performance at a
lower cost while maintaining all functional
requirements defined by the customer

24. Design Team
• Traditional approach
– “We design it, you build it” or “over the
wall”
• Concurrent engineering
– “Let’s work together simultaneously”
– A new approach to design that involves
simultaneous design of products and
processes by design teams

25. •© 2007 Wiley
cont..
• Old “over-the –wall” sequential design
process should not be used
– Each function did its work and passed it to the
next function
• Replace with a Concurrent Engineering
process
– All functions form a design team working
together to develop specifications, involve
customers early, solve potential problems,
reduce costs, & shorten time to market

Design of Services
• Service design is unique in that the service and
entire service concept are being designed
– must define both the service and concept
- Physical elements, aesthetic & psychological
benefits
e.g. promptness, friendliness, ambiance
– Product and service design must match the needs and
preferences of the targeted customer group

27. Characteristics of a Well-Designed
Service System
1. Each element of the service system is consistent with
the operating focus of the firm.
2. It is user-friendly.
3. It is robust.
4. It is structured so that consistent performance by its people and
systems is easily maintained.
3 - 27

28. Characteristics of a Well-Designed
Service System (Continued)
5. It provides effective links between the
back office and the front office so that
nothing falls between the cracks.
6. It manages the evidence of service quality
in such a way that customers see the
value of the service provided.
7. It is cost-effective.
3 - 28

29. Major Elements in Designing a Service
Organization
1.Identification of the target market-Who is the customer?
2.Defining the service concept –How do we differentiate our
service in the market?
3.Defining the service strategy-What is our service package
and the operating focus of our service?
4.Defining the service delivery system-What are the actual
processes , staff and facilities by which the service is
created?
