  • Products and Services

5
Product Design
  • Specifies materials
  • Determines dimensions tolerances
  • Defines appearance
  • Sets performance standards

6
Service Design
  • Specifies what the customer is to experience
  • Physical items
  • Sensual benefits
  • Psychological benefits

7
An Effective Design Process
  • Matches product/service characteristics with
    customer needs
  • Meets customer requirements in simplest, most
    cost-effective manner
  • Reduces time to market - haste vs. speed to
    market
  • Minimizes revisions - quality designed into the
    product

8
Stages in the Design Process
  • Idea Generation Product Concept - can you
    create your own market? What role does the voice
    of the customer play in idea generation?
  • Feasibility Study Performance Specifications
  • Preliminary Design Prototype - testing and
    redesign
  • Final Design Final Design Specifications
  • Process Planning Manufacturing Specifications
    - make to order/stock assembly line?

9
The Design Process
10
Idea Generation
  • Suppliers, distributors, salespersons
  • Trade journals and other published material
  • Warranty claims, customer complaints, failures
  • Customer surveys, focus groups, interviews
  • Field testing, trial users
  • Research and development

11
More Idea Generators
  • Perceptual Maps
  • Visual comparison of customer perceptions
  • Benchmarking
  • Comparing product/service against best-in-class
  • Reverse engineering
  • Dismantling competitors product to improve your
    own product

15
Risk Analysis

  • Retest

17
Functional Design(How the Product Performs)
  • Reliability
  • Probability product performs intended function
    for specified length of time
  • Maintainability
  • Ease and/or cost or maintaining/repairing product

24
Production Design
  • Part of the preliminary design phase
  • Simplification
  • Standardization
  • Modularity

25
Final Design Process Plans
  • Produce detailed drawings specifications
  • Create workable instructions for manufacture
  • Select tooling equipment
  • Prepare job descriptions
  • Determine operation assembly order
  • Program automated machines

26
Improving the Design Process
  • Design teams
  • Concurrent design
  • Design for manufacture assembly
  • Design to prevent failures and ensure value
  • Design for environment
  • Measure design quality
  • Utilize quality function deployment
  • Design for robustness
  • Engage in collaborative design

27
Breaking Down Barriers to Effective Design
28
Design Teams
Preferred solution cross functional teams
  • Marketing, manufacturing, engineering
  • Suppliers, dealers, customers
  • Lawyers, accountants, insurance companies

29
Concurrent Design
  • Improves quality of early design decisions
  • Decentralized - suppliers complete detailed
    design
  • Incorporates production process
  • Scheduling and management can be complex as tasks
    are done in parallel
  • include the customer in the process!!

30
Design for Manufacture and Assembly
  • Design a product for easy economical production
  • Incorporate production design early in the
    design phase
  • Improves quality and reduces costs
  • Shortens time to design and manufacture
  • also known as Design for Six Sigma

31
Design for Six Sigma
  • Define the goals of the design activity
  • Measure customer input to determine what is
    critical to quality from the customers
    perspective what are customer delighters? What
    aspects are critical to quality?
  • Analyze innovative concepts for products and
    services to create value for the customer
  • Design new processes, products, and services to
    deliver customer value
  • Verify new systems perform as expected

32
DFM Guidelines
  • Minimize the number of parts, tools, fasteners,
    and assemblies
  • Use standard parts and repeatable processes
  • Modular design
  • Design for ease of assembly, minimal handling
  • Allow for efficient testing and parts replacement

33
Design Review
  • Failure Mode and Effects Analysis (FMEA)
  • A systematic approach for analyzing causes
    effects of failures
  • Prioritizes failures
  • Attempts to eliminate causes

34
Value Analysis (Value Engineering)
Is there value added?
  • Ratio of value / cost
  • Assessment of value
  • 1. Can we do without it?
  • 2. Does it do more than is required?
  • 3. Does it cost more than it is worth?
  • 4. Can something else do a better job
  • 5. Can it be made by less costly method, tools,
    material?
  • 6. Can it be made cheaper, better or faster by
    someone else? Should we contract it out?

35
Design for Environment
  • Design from recycled material
  • Use materials which can be recycled
  • Design for ease of repair
  • Minimize packaging
  • Minimize material energy used during
    manufacture, consumption disposal
  • green laws in Europe -

36
Examples
  • Recycling of oil
  • carpets in land fills - 4 billion pounds in land
    fills annually
  • Xerox and Hewlett-Packard - pay for return of
    printer cartridges on larger printers

37
Design for Robustness
  • Product can fail due to poor design quality
  • Products subjected to many conditions
  • Robust design studies
  • Controllable factors - under designers control
  • Uncontrollable factors - from user or environment
  • Designs products for consistent performance

38
Characteristics of Services
  • Services are intangible
  • Service output is variable
  • Service have higher customer contact
  • Services are perishable
  • Service inseparable from delivery
  • Tend to be decentralized and dispersed
  • Consumed more often than products
  • Services can be easily emulated
  • Call girl principle value diminishes after
    service is rendered

39
A Well-Designed Service System is
  • Consistent with firms strategic focus
  • Customer friendly
  • Easy to sustain
  • Effectively linked between front back office
  • Cost effective
  • Visible to customer
