32. Product Development Chapter 6

33. Introduction 1. Analyze market to assess need 2. Design product 3. Design process for making product 4. Develop plan to market product 5. Develop plan for full-scale production 6. Analyze financial feasibility Product Development is a process which generates concepts, designs, and plans to create services and goods to meet customer needs.

34. Increasing Importance of Product Development 1.Customers demand greater product variety. 2.Customers are causing shorter product life cycles. 3.Improving technology is causing new products to be introduced 4.The impact of increasing product variety and shortening product life cycles is having a multiplicative effect on the need for product development. 5.Today, in order to be competitive, the firm may have to produce many different products with a life cycle of only five years or less. End of Life issues

35. Product Design Specifies materials Determines dimensions & tolerances Defines appearance Sets performance standards

36. Service Design Specifies what the customer is to experience Physical items Sensual benefits Psychological benefits

37. 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

38. 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?

39. 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

40. More Idea Generators Perceptual Maps Visual comparison of customer perceptions Benchmarking Comparing product/service against best-in-class Reverse engineering Dismantling competitor’s product to improve your own product

44. Feasibility Study Market Analysis - Market Segmentation Economic Analysis Technical / Strategic Analysis Performance Specifications Risk Analysis

45. Economic Analysis Can we produce it at a volume to make a profit? If not, why produce? How many do we have to make to break even?

46. Break Even Analysis Total Costs = Total Revenues (Volume x Price) = (Fixed Costs + Variable Costs) Profit = (Total Revenue – Total Costs) Fixed Costs Sales Price – Variable Costs B/E Point =

47. Example Fixed Costs = $2000 Variable Costs = $5/item Sales Price = $10/item Fixed Costs ($2000) Sales Price ($10) – Variable Costs ($5) B/E PT = B/E point = ($2000/$5) 400 items

48. Risk Analysis 1. Identify the Hazards 2.Assess hazards to determine risks. 3.Develop controls and make risk decisions. 4.Implement controls. 5.Supervise and evaluate.

50. Preliminary Design Create form & functional design Build prototype Test prototype Revise prototype Retest How will it look?

51. 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

57. Design Teams Marketing, manufacturing, engineering Suppliers, dealers, customers Lawyers, accountants, insurance companies Preferred solution = cross functional teams

58. 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!!

59. 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

60. 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

61. DFM Guidelines 1.Minimize the number of parts, tools, fasteners, and assemblies 2.Use standard parts and repeatable processes 3.Modular design 4.Design for ease of assembly, minimal handling 5.Allow for efficient testing and parts replacement

62. Design for Assembly (DFA) Procedure for reducing number of parts Evaluate methods for assembly Determine assembly sequence

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

64. Value Analysis (Value Engineering) 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? Is there value added?

65. 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 -

67. Design for Robustness Product can fail due to poor design quality Products subjected to many conditions Robust design studies Controllable factors - under designer’s control Uncontrollable factors - from user or environment Designs products for consistent performance

68. A Well-Designed Service System is Consistent with firm’s strategic focus Customer friendly Easy to sustain Effectively linked between front & back office Cost effective Visible to customer

69. 69 CHAPTER 8 Process Selection affects the outcome – in production or sports:

70. 70 What is Process Selection? Series of decisions that includes technical/engineering issues and volume/scale issues Technical/engineering: basic methods that produce a good or service Scale: how many or how much to produce; how many to serve at a time Trade off analysis between capacity and costs

71. 71 Why process selection is critical Dell – from make/assemble to order in Texas to make/assemble to stock off shore Does this work? Break even analysis may depend on process costs Which process gives the lowest costs – assumption?

72. The Point of Indifference Comparing Two Processes What is it? Who cares? How do you calculate it? 72

73. Comparing Two Processes Process A Fixed = $2000 Variable = $5/item Process B Fixed = $11000 Variable = $2/item

74. Fixed A + (Var A )x = Fixed B + (Var B )x 2000 + 5x = 11,000 + 2x 3x = 9000 X = 3000 So what? Comparing the Processes

75. 75 Trade off analysis Customer demanded quantity drives the trade off analysis and decision process Example: → retail stocks at Christmas 2008 and 2009 season - goal save money by stocking less → At what point do you lose sales due to lower stockage levels?

76. 76 Process Design/Selection/Capacity Have to be simultaneous operations – some texts suggest sequential steps Decision process has to be customer based → what should it be? → how many should be produced/how many are we capable of producing? → how should it be produced?

77. 77 Process Strategy - Defines Capital intensity Process flexibility Vertical integration Customer involvement

78. 78 Goal of Process Design Reduce lead time for product to the customer Is it best to be the first to market and establish the market? Or, be the follower and let someone else do the R&D/design/risk?

79. 79 Problems with Managing Large, Unfocused Operations Growing facilities add more levels of management and make coordination and control difficult. New products are added to the facility as customers demand greater product variety. Hidden overhead costs increase as managers add staff to deal with increased complexity.
