  1. 1. Product andService Design
  2. 2. Product and Service Design Major factors in strategy  Cost  Quality  Time-to-market  Customer satisfaction  Competitive advantage
  3. 3.  Increased emphasis on or attention to:  Customer satisfaction  Reducing time to introduce new product or service  Reducing time to produce product
  4. 4.  Increased emphasis on or attention to:  The organization’s capabilities to produce or deliver the item  Environmental concerns  Designing products & services that are “user friendly”  Designing products that use less material
  5. 5.  Development time and cost Product or service cost Resulting product or service quality Capability to produce or deliver a given product or service
  6. 6.  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
  7. 7.  Economic reasons Social and demographic Reasons Political, Liability, or Legal Life cycle Competitive Cost or availability Technological
  8. 8.  Legal  Product liability  Uniform commercial code Ethical  Releasing products free of defects Environmental  EPA
  9. 9.  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.
  10. 10. Saturation MaturityDemand Decline Growth Incubation Time
  11. 11.  Modification Expansion Clone New
  12. 12.  Idea Generation Feasibility Analysis Product specification Process specification Prototype development Design review Market test Product Introduction and follow-up
  13. 13.  Internal  Employees  Marketing department  R&D department External  Customers  Competitors  Suppliers
  14. 14.  Fewer parts to deal with in inventory & manufacturing Reduced training costs and time More routine purchasing, handling, and inspection procedures
  15. 15.  Orders fillable from inventory Opportunities for long production runs and automation Need for fewer parts justifies increased expenditures on perfecting designs and improving quality control procedures.
  16. 16.  Designs may be frozen with too many imperfections remaining. High cost of design changes increases resistance to improvements. Decreased variety results in less consumer appeal.
  17. 17. Mass customization:  A strategy of producing standardized goods or services, but incorporating some degree degree of customization  Delayed differentiation  Modular design
  18. 18. Delayed differentiation is apostponement tactic Producing but not quite completing a product or service until customer preferences or specifications are known
  19. 19. Modular design is a form of standardization inwhich component parts are subdivided intomodules that are easily replaced orinterchanged. It allows:  easier diagnosis and remedy of failures  easier repair and replacement  simplification of manufacturing and assembly
  20. 20.  Design for manufacturing (DFM) Design for assembly (DFA) Design for recycling (DFR) Remanufacturing Design for disassembly (DFD) Robust design
  21. 21. Beyond the overall objective to achievecustomer satisfaction while making a reasonableprofit is:Design for Manufacturing(DFM)The designers’ consideration of theorganization’s manufacturing capabilities whendesigning a product.The more general term design for operationsencompasses services as well as manufacturing
  22. 22. Reverse engineering is thedismantling and inspectingof a competitor’s product todiscover productimprovements.
  23. 23. Concurrent engineeringis the bringing togetherof engineering design andmanufacturing personnelearly in the design phase.
  24. 24.  Manufacturability is the ease of fabrication and/or assembly which is important for:  Cost  Productivity  Quality
  25. 25.  Computer-Aided Design (CAD) is product design using computer graphics.  increases productivity of designers, 3 to 10 times  creates a database for manufacturing information on product specifications  provides possibility of engineering and cost analysis on proposed designs
  26. 26. Recycling Recycling: recovering materials for future use Recycling reasons  Cost savings  Environment concerns  Environment regulations
  27. 27. Robust DesignRobust Design: Design that results inproducts or services that can functionover a broad range of conditions
  28. 28. 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
