3. in developing markets such as China and India, consumers can’t afford large, expensive cars, much less drive them in overcrowded population centers. Fuel efficiency as well as environmental concerns are also important, as developing nations seek to cap carbon emissions even as the number of vehicles on their streets continues to rise. But these consumers are not willing to buy inferior cars that simply cost less. Rather, like most of us, they want low-cost vehicles that are designed to meet their needs and still have high quality, reliability, and style—in other words, have value. Consumers in India, for instance, need cars that maximize passenger room because they use their autos primarily as family vehicles to drive around town; by contrast, in the West, with its better roads and routine long-distance driving, cargo capacity matters more.

4. Indian drivers are willing to pay a bit more for cars that offer the latest in comfort, safety, and utility, but not for cars with power windows and locks or fancy sound systems. Automatic transmissions are desirable in India and China—nobody wants to keep pressing the clutch and shifting gears in the inevitable stop-and-go traffic—but powerful engines are not. Succeeding in developing markets, therefore, requires rethinking from start to finish how new cars should be designed and built. It calls for a deep understanding of the unique needs of consumers and the ability to assemble the combination of power trains, bodies, features, and options that best match those desires—at affordable prices.

5. What do you think?
How important are design and value in your purchasing decisions? Provide examples for goods and services.

6. Every design project—a new automobile or cell phone, a new online or financial service, and even a new pizza—is a series of trade-offs: between technology and functionality, between ambition and affordability, between the desires of the people creating the object and the needs of the people using it.

9. Designing Goods and Services
CBP design and configuration choices revolve around a
solid understanding of customer needs and target markets,
and the value that customers place on attributes, such as:
Time: Reduce waiting time, be more responsive to customer needs.
Place: Select location for customer convenience.
Information: Provide product support, user manuals.
Entertainment: Enhance customer experience.
Exchange: Multiple channels used for purchases.
Form: How well the physical characteristics of a good address customer needs. 9

10. Designing Goods and Services

11. Designing Goods and Services
The design of a manufactured good focuses on its physical characteristics—dimensions, materials, color, and so on.
The design of a service, however, cannot be done independently from the “process” by which the service is delivered. The process by which the service is created and delivered (that is, “produced”) is, in essence, the service itself! 11

12. Designing Goods and Services
Prototype testing is the process by which a model (real or simulated) is constructed to test the good’s physical properties or use under actual operating conditions, as well as consumer reactions to the prototype.

13. Customer-Focused Design
Customer requirements, as expressed in the customer’s own terms, are called the voice of the customer.
Quality function deployment (QFD) is an approach to guide the design, creation, and marketing of goods and services by integrating the voice of the customer into all decisions.
QFD translates customer wants and needs into technical requirements of a product or service.

14. The House of Quality Building the House of Quality:
Determine customer requirements through the voice of the customer (VOC).
Define technical requirements of the product.
Determine interrelationships between the technical requirements.
The relationship matrix defines what technical requirements satisfy VOC needs.
Customer priorities and competitive evaluation help select which VOC requirements the product should focus on.

18. Tolerance Design and the Taguchi Loss Function
For most manufactured goods, design blueprints specify a target dimension (called the nominal), along with a range of permissible variation (called the tolerance). For example,  cm.
The nominal dimension is cm, but may vary anywhere in the range from to cm.
This is sometimes called the “goal post model.”

19. Exhibit 6.3 Traditional Goal Post View of Conforming to Specifications

20. Tolerance Design and the Taguchi Loss Function
Genichi Taguchi, a Japanese engineer, maintained that the traditional practice of setting design specifications is inherently flawed. Taguchi argued that the smaller the variation about the nominal specification, the better is the quality. In turn, products are more consistent, would fail less frequently, and thus, be less costly in the long run.

21. Tolerance Design and the Taguchi Loss Function
L(x) = k(x – T )2 [6.1]
Where:
L(x) is the monetary value of the loss associated with deviating from the target, T;
x is the actual value of the dimension;
k is a constant that translates the deviation into dollars.

22. Exhibit 6.4 Nominal-Is-Best Taguchi Loss Function

24. Solved Problem
Suppose that the specification on a part is ± cm. A detailed analysis of product returns and repairs has discovered that many failures occur when the actual dimension is near the extreme of the tolerance range (that is, when the dimensions are approximately 0.48 or 0.52) and costs $50 for repair.
Thus, in Equation 6.1, the deviation from the target, x – T , is 0.02 and
L(x) = $50. Substituting these values, we have:
50 = k(0.02)2 or
k = 50/ = 125,000
Therefore, the loss function for a single part is L(x) = (x – T)2.
This means when the deviation is 0.10, the firm can still expect a loss per unit of: L(0.51) = 125,000(0.10)2 = $12.50 per part

26. Design for Reliability
Reliability is the probability that a manufactured good, piece of equipment, or system performs its intended function for a stated period of time under specified operating conditions.

27. Design for Reliability
Reliability is a probability, that is, a value between 0 and 1.
Example: A reliability of 0.97 means that on average, 97 of 100 times the item will perform its function for a given period of time under specified operating conditions.
Many designs have components arranged in series; others consist of parallel components that function independently of each other.

28. Design for Reliability
In a series system, if one component fails, the entire system fails. The reliability of a series system is the product of the individual probabilities of each process in a system.
Rs = (p1)(p2)(p3). . . (pn) [6.2]
Exhibit Structure of a Serial System

29. Design for Reliability
In parallel systems, functions are independent and the entire system will fail only if all components fail. The reliability of a parallel system is computed as:
Exhibit Structure of a Parallel System
Rp = 1 – (1 – p1)(1 – p2)(1 – p3). . . (1 – pn) [6.3]

30. Design for Reliability
Example: The reliability of this series system is:
Rs = (.98)(.91)(.99) = or 88.3%
Exhibit Subassembly Reliabilities

31. Design for Reliability
Series-Parallel Systems: The reliability of the parallel system for subassembly B is: Rp = 1 – (1 – .91)(1 – .91) = 1 – =
Exhibit Modified Design
Thus, the reliability of the entire system is:
Rs = (.98)(.9919)(.99) = .962 or 96.2%.

32. Design for Manufacturability
Design for manufacturability (DFM) is the process of designing a product for efficient production at the highest level of quality.
Product simplification is the process of trying to simplify designs to reduce complexity and costs and thus improve productivity, quality, flexibility, and customer satisfaction.

33. Design for Manufacturability

34. Design for Sustainability
Many products are discarded simply because the cost of maintenance or repair is too high when compared with the cost of a new item. One aspect of designing for sustainability is designing products that can easily be repaired and refurbished or otherwise salvaged for reuse.
Design for Environment (DfE) is the explicit consideration of environmental concerns during the design of goods, services, and processes and includes such practices as designing for recycling and disassembly.

35. Design for Sustainability

36. Design for Sustainability

37. Service Delivery System Design
Service delivery system design includes the following:
Facility location and layout
The servicescape
Process and job design
Technology and information support systems
Organizational structure

38. Service Delivery System Design
Facility Location and Layout
Location creates customer’s convenience.
Great store layout, process design, and service encounter design are meaningless if the store is in the wrong location.
The Internet is making physical locations less important for some information-intensive services such as Charles Schwab, Vanguard, and Scottrade.

39. Service Delivery and System Design
Servicescape
All of the physical evidence a customer might use to form an impression.
The servicescape provides the behavioral setting where service encounters take place.
Standardization of the servicescape and service processes enhances efficiency, especially for multiple site organizations.

40. Three Dimensions of a Servicescape
Ambient conditions—manifest by sight, sound, smell, touch, and temperature; five human senses; e.g., leather chairs in the lobby, cartoon characters in children’s hospital, music at a coffee shop.
Spatial layout and functionality—how furniture, equipment, and office spaces are arranged; also streets, parking lots, stadiums, etc.
Signs, symbols, and artifacts—explicit signals that communicate an image of the firm; e.g., diplomas hanging on the wall in a medical clinic, company logos and uniforms, artwork, mission statements.

42. Types of Servicescapes
Some servicescapes, termed lean servicescape environments, are very simple.
Examples: Ticketron outlets, FedEx drop-off kiosks
More complicated designs and service systems are termed elaborate servicescape environments.
Examples: Hospitals, airports, universities

43. Service Process and Job Design
Service process design is the activity of developing an efficient sequence of activities to satisfy internal and external customer requirements.
Develop procedures to ensure that:
Things are done right the first time.
Interactions between customers and service providers are simple and quick.
Human error is avoided.

44. Service Process and Job Design
Technology and Information Support Systems
What technology does each job require?
What information technology best integrates all parts of the value chain?
Technology ensures speed, accuracy, customization, and flexibility.

45. Technology and Information Support Systems

46. Service Process and Job Design
Organizational Structure
Pure functional organization requires more handoffs between work activities and results in increased opportunity for error and slower processing times.
Process-based organization leverages cross-functionality of service processes.

47. Service Encounter Design
Service encounter design focuses on the interaction, directly or indirectly, between the service provider(s) and the customer.
Principal elements:
Customer contact behavior and skills
Service provider selection, development, and empowerment
Recognition and reward
Service recovery and guarantees

48. Service Encounter Design
Customer Contact Behavior and Skills
Customer contact refers to the physical or virtual presence of the customer in the service delivery system during a service experience.
Customer contact is measured by the percentage of time the customer must be in the system relative to the total time it takes to provide the service.
Systems in which the percentage is high are called high-contact systems; those in which it is low are called low-contact systems.

49. Service Encounter Design
Customer-contact requirements are measurable performance levels or expectations that define the quality of customer contact with representatives of an organization.
Examples:
Answering a telephone within two rings
Using a customer’s name whenever possible

50. Service Encounter Design
Service Provider Selection, Development and Empowerment
Recruit and train employees to exceed customer expectations.
Empowerment simply means giving people authority to make decisions based on what they feel is right, to have control over their work, to take risks and learn from mistakes, and to promote change.
Ritz-Carlton Hotel employees can spend up to $2,000 to resolve customer complaints with no questions asked.

51. Service Encounter Design
Recognition and Reward
Key motivational factors:
Recognition
Advancement
Achievement
Nature of the work

52. Service Encounter Design
Service Guarantees and Recovery
A service upset is any problem a customer has—real or perceived—with the service delivery system and includes terms such as service failure, error, defect, mistake, or crisis.
A service guarantee is a promise to reward and compensate a customer if a service upset occurs during the service experience.

53. Service Encounter Design
Service Guarantees and Recovery
Service recovery is the process of correcting a service upset and satisfying the customer.
Begin immediately after a service upset.
Document the process and train employees.
Listen to the customer and respond sympathetically.
Resolve the problem quickly, provide an apology, offer compensation.

55. An Integrative Case Study of LensCrafters
LensCrafters’ ( mission statement suggests that time and service quality are the most important competitive priorities and potential order winners.
CBP is the integrated set of goods (eyewear) and services (accurate eye exam and one-hour service).

56. An Integrative Case Study of LensCrafters
