Humor in Product Design

Need-satisfying offering of an organization Example
P&G does not sell laundry detergent P&G sells the benefit of clean clothes
Customers buy satisfaction, not parts May be a good or a service
What is a Product?

Product Strategy Options
Product differentiation
Low cost
Rapid response

Sociological and demographic changeTechnological change
Political/legal changeChanges inmarket practiceprofessional standardssuppliers and distributors
12
Legislation/ Implementation Date Stated Purpose Industry CriticismElectrical-Waste directive (2006)
Makes electrical equipment easier to recycle in part by banning some hazardous substances
Bans some common flame retardants, raising the likelihood of fires
Telecom-data-protection directive (mid-2003)
Protects privacy on e-mail and the internet
Makes surfing more onerous by restricting use of “cookies” to remember peoples preferences
Biotech-Labeling laws (2003) Strengthens existing food-label laws and introduces labeling for animal feed containing genetically modified content
Encourages food processors and supermarkets to avoid using genetically modified ingredients, and farmers could stop growing them
Pedestrian-protection initiative (2001-2012) (when all new cars sold in Europe must comply)
Reduces injuries and casualties in road accidents
Raises costs of cars and restricts automaker’s design freedom
Chemicals review (staggered through 2012)
Eliminates health hazards due to chemicals
Restricts even minute use of dangerous substances, such as ethanol, in products such as cosmetics and detergents

Idea Generation Stage
Provides basis for entry into market Sources of ideas
Market need (60-80%); engineering & operations (20%); technology; competitors; inventions; employees
Follows from marketing strategy Identifies, defines, & selects best market
opportunities
29
Customer Requirements Stage Identifies & positions key
product benefits Stated in core benefits
proposition (CBP) Example: Long lasting
with more power (Sears’ Die Hard Battery)
Identifies detailed list of product attributes desired by customer Focus groups or
1-on-1 interviews

Functional Specification Stage Defines product in terms of how the product would meet
desired attributes Identifies product’s engineering characteristics
Example: printer noise (dB)
Prioritizes engineering characteristics May rate product compared to competitors’

Quality Function Deployment
Product design process using cross-functional teams Marketing, engineering, manufacturing
Translates customer preferences into specific product characteristics
Involves creating 4 tabular ‘Matrices’ or ‘Houses’ Breakdown product design into increasing
levels of detail
33
You’ve been assigned temporarily to a QFD team. The goal of the team is to develop a new camera design. Build a House of Quality.

Organizing for Product Development
Historically – distinct departments Duties and responsibilities are defined Difficult to foster forward thinking
Today – team approach Representatives from all disciplines or
functions Concurrent engineering – cross functional
team
41
Manufacturability and Value Engineering
Benefits: reduced complexity of products additional standardization of products improved functional aspects of product improved job design and job safety improved maintainability of the product robust design
42
Cost Reduction of a Bracket via Value Engineering
43
Issues for Product Development
Robust design Time-based competition Modular design Computer-aided design Value analysis Environmentally friendly design
44
Robust Design
Product is designed so that small variations in production or assembly do not adversely affect the product
45
Modular Design
Products designed in easily segmented components.
Adds flexibility to both production and marketing
46
Designing products at a computer terminal or work station Design engineer
develops rough sketch of product
Uses computer to draw product
Often used with CAM© 1995 Corel Corp.
Computer Aided Design (CAD)
47
Shorter design time Database availability New capabilities
Example: Focus more on product ideas
Improved product quality Reduced production costs
Benefits of CAD/CAM
48
Design for Manufacturing and Assembly (DFMA) 3-D Object Modeling CAD/CAM – CAD info is translated into machine
control instructions (CAM)
© 1995 Corel Corp.
Extensions of CAD
49
Virtual Reality
Computer technology used to develop an interactive, 3-D model of a product.
Especially helpful in design of layouts (factory, store, home, office)
50
Value Analysis
Focuses on design improvement during production
Seeks improvements leading either to a better product or a product which can be more economically produced.
51
Environmentally Friendly Designs
Benefits Safe and environmentally sound products Minimum raw material and energy waste Product differentiation Environmental liability reduction Cost-effective compliance with
environmental regulations Recognition as good corporate citizen
52
“Green” Manufacturing
Make products recyclable Use recycled materials Use less harmful ingredients Use lighter components Use less energy Use less material
53
Time-based Competition
Product life cycles are becoming shorter.
Faster developers of new products gain on slower developers and obtain a competitive advantage
54

Make-or-Buy Decisions
Decide whether or not you want (or need) to produce an item
May be able to purchase the item as a “standard item” from another manufacturer

Parts grouped into families Similar, more standardized parts
Uses coding system Describes processing & physical
characteristics

Engineering Change Notice (ECN)
A correction or modification of an engineering drawing or bill of material
73
Configuration Management
A system by which a product’s planned and changing components are accurately identified and for which control and accountability of change are maintained
74
Service Design - Nature of Customer Participation
75
Improving Customer Relations at a Drive-up Window
Be especially discreet when talking with customer through the
microphone
Provide written instructions for customers who must fill out forms you
provide
Mark lines to be completed or attach a note with instructions
Always say ”please” and “thank you”
Establish eye contact with the customer if the distance allows it
If the transaction requires that the customer park the car and come into
the lobby, apologize for the inconvenience.
76
Moment-of-Truth at a Computer Company
Experience Detractors
I had to call more than once to get through.
A recording spoke to me rather than a person
While on hold, I get silence,and wonder if I am disconnected.
The operator sounded like he was reading a form of routine questions.
The operator sounded uninterested
I felt the operator rushed me.
Standard Expectations
Only one local number needs to be dialed
I never get a busy signal
I get a human being to answer my call quickly and he or she is pleasant and responsive to my problem
A timely resolution to my problem is offered
The operator is able to explain to me what I can expect to take place
Experience Enhancers
The operator was sincerely concerned and apologetic about my problem
He asked intelligent questions that allowed me to feel confident in his abilities
The operator offered various times to have work done, to suit my schedule
Ways to avoid future problems were suggested
77
Application of Decision Trees to Product Design
Particularly useful when there are a series of decisions and outcomes which lead to other decisions and outcomes.
Considerations: Include all possible alternatives and states of nature -
including “doing nothing” Enter payoffs at end of branch Approach determining expected values by “pruning”
tree
78
Transition to Production First issue: knowing when to move to production! Second: must view product development as evolutionary,
not responsibility of single individual/department Third: expect to need a trial production period to work the
bugs out Fourth: recognize that responsibility must also transition
