  1. Chapter 4Product and Service Design Spice Giant McCormick Demand for traditional spices going down

  2. Product and Service Design Organization’s strategy

  3. Translate customer wants and needs into product and service requirements Refine existing products and services Develop new products and services Formulate quality goals Formulate cost targets Construct and test prototypes Document specifications Product or Service Design Activities

  4. Objectives of P/S Design • Designing For Operations • Capabilities? • Productivity, quality, costs!

  5. Product Liability - A manufacturer is liable for any injuries or damages caused by a faulty product. Uniform Commercial Code - Products carry an implication of merchantability and fitness. Legal, Ethical, and Environmental Issues

  6. Other Issues in P/S Design

  7. Saturation Maturity Decline Demand Growth Introduction Time Figure 4.1 Life Cycles of Products or Services

  8. Standardization- an absence of variety

  9. Mass customization A strategy of producing standardized goods or services, but incorporating some degree of customization • Delayed differentiation • Modular design

  10. Reliability • The ability of a product, part, or system to perform its intended function under a prescribed set of conditions

  11. Improving Reliability • Component design • Production/assembly techniques • Testing • Redundancy/backup • Preventive maintenance procedures • User education • System design

  12. Robust Design • Design that results in products or services that can function over a broad range of conditions

  13. Degree of Design Change Table 4.3

  14. Multinational companies must take into account cultural differences related to the product design. Notable failures: International House of Pancakes- IHOP in Bangladesh Ikea beds in U.S. Cultural Differences

  15. Uses combined efforts of a team of designers working in different countries Provides a range of comparative advantages over traditional teams such as: Engaging the best human resources around the world Possibly operating on a 24-hr basis Global customer needs assessment Global design can increase marketability Global Product Design- Virtual teams RMG

  16. Phases in Product Development Process

  17. Research & Development (R&D) • Organized efforts to increase scientific knowledge or product innovation & may involve: • Basic Research advances knowledge about a subject without near-term expectations of commercial applications. • Applied Research achieves commercial applications. • Development converts results of applied research into commercial applications.

  18. Manufacturability is the ease of fabrication and/or assembly which is important for: Cost Productivity Quality Manufacturability

  19. Design for manufacturing (DFM) Design for assembly (DFA) Design for recycling (DFR) Remanufacturing Design for disassembly (DFD) Product design consideration

  20. Multiple products or product families that have a high degree of similarity can share components Automakers using internal parts Engines and transmissions Water pumps Etc. Other benefits Reduced training for assemble and installation Reduced repair time and costs Component Commonality

  21. Correlation matrix Design requirements Customer require- ments Relationship matrix Competitive assessment Specifications or target values The House of Quality • Quality Function Deployment • Voice of the customer • House of quality QFD: An approach that integrates the “voice of the customer” into the product and service development process.

  23. The Kano Model of Customer Satisfaction • Classifies product attributes based on how they are perceived by customers and their effect on customer satisfaction. • Useful for guiding design decisions • When good is good enough, and when more is better.

  24. The Kano Model A competitive product meets basic attributes, maximizes performances attributes, and includes as many “excitement” attributes as possible at a cost the market can bear. high customer satisfaction no dissatisfaction * Cup Holders customer satisfaction * fuel economy Must haves- no product differentiation

  25. Service Design

  26. Service design involves The physical resources needed The goods that are purchased or consumed by the customer Explicit services Implicit services Service Design

  27. Differences Between Product and Service Design • Tangible – intangible • Services created and delivered at the same time • Services cannot be inventoried • Services highly visible to customers • Services have low barrier to entry • Location important to service • Range of service systems • Demand variability Ch- 1

  28. Service systems range from those with little or no customer contact to very high degree of customer contact such as: Insulated technical core (software development) Production line (automatic car wash) Personalized service (hair cut, medical service) Consumer participation (diet program) Self service (supermarket) Service Systems

  29. Demand variability creates waiting lines and idle service resources Service design perspectives: Cost and efficiency perspective Customer perspective Customer participation makes quality and demand variability hard to manage Attempts to achieve high efficiency may depersonalize service and change customer’s perception of quality Service Demand Variability

  32. Service blueprinting A method used in service design to describe and analyze a proposed service A useful tool for conceptualizing a service delivery system Service Blueprinting Step 6 Add evidence of service at each customer action step. Step 4 Map contact employee actions, onstage and back-stage. Step 3 Map the process from the customer’s point of view. Step 1 Identify the process to be blue-printed. Step 2 Identify the customer or customer segment. Step 5 Link customer and contact person activities to needed support functions.

  33. Evidence Client Steps On Stage Journey Energy Provider Steps Energy Provider Steps • How will my energy meter help me use energy more efficiently? • Receiving a home metering device to measure personal energy consumption • Basic customer steps and backstage activities are mapped out Back Stage Processes Backend Applications

  34. Evidence New Energy meter arrives Energy consumption visualized Reduced usage Conduct normal appliance usage Gee – how would consumption differ if I selected “light” load for my dishwasher? On Stage Journey Read meter Run appliance again Client Steps Follow meter instructions Read meter Energy Provider Steps Install Meter, give client instruction package Energy Provider Steps Back Stage Processes Push feedback of use to meter in home Push feedback of use to meter in home Backend Applications Add readout to data base for future analytics

  35. Characteristics of a good Service Systems • Consistent with the organization mission • User friendly • Robust • Easy to sustain • Cost effective • Value to customers • Effective linkages between back operations • Single unifying theme • Ensure reliability and high quality

  36. Guidelines for Successful Service Design

  37. Increase emphasis on component commonality Package products and services Use multiple-use platforms Consider tactics for mass customization Look for continual improvement Shorten time to market Operations Strategy
