  • 16. Managing Design and Development Process
    • Planning, organizing, staffing, leading, and controlling the limited resources
    • SEQUENTIAL DESIGN AND DEVELOPMENT
    • Before 1985, most American firms have organized their product design and development process sequentially. The sequence typically emerges as each functional area completes its part of the project before passing on the results to the next operation.
  • 17. Managing Design and Development Process
    • SHORTCOMINGS:
      • Frequent engineering changes (before and after product launch)
      • Ineffective communication
      • Lack of prospective thinking.
      • Longer design and development lead time
  • 18. Managing Design and Development Process
    • CONCURRENT DESIGN AND DEVELOPMENT (CONCURRENT ENGINEERING)
    • This method sets up a comprehensive process for completing the steps in design and development through a continuing involvement of cross-functional teams of organization members.
  • 19. Managing Design and Development Process
    • MAIN BENEFITS:
    • Shorter development cycle
    • Better cross-functional communication
    • Teamwork
    • Clear perspective.
    • In practice, concurrent engineering and sequential process are both important
  • 20. 72-Seat Regional Propeller Aircraft: Q400 Project
  • 21. Snapshot of Aircraft Development Beginning in spring 1996, about 380 engineers and professionals from Bombardier and its major suppliers work together in a football-size design department for the Joint Definition Phase of Q400. In this phase, all major disciplines involved in aircraft design are represented. They included engineering, design, tooling, manufacturing, marketing, sales, procurement, customer/field support, spare parts, training, publications and many more. This phase also involved refining project objectives and further negotiations. Such a co-location of company engineers and suppliers benefits both parties. It facilitates superior communication among all functions and leverages suppliers' knowledge so that new process technology can be incorporated into product development.
  • 22. Snapshot of Aircraft Development Milestones in this 6-month JDP, including different Deign Reviews, were to determine specific targets for delivering the commitments. These iterative and interactive loops are to drive and check the detailed timing and specs from all areas. When this process was completed, it was subject to a series of Participant Exit Reviews to freeze every interface design of different structures and systems. When the Project Director accepted that review, the representatives and suppliers involved could then exit the JDP process to complete their detailed design of items under their responsibility and prepare for production.

  • 36. Quality Function Deployment
    • The Quality Function Deployment (QFD) tool is used to meet customers’ requirements throughout the design process and also in the design of production systems. It is a customer-driven quality planning process to guide design, manufacturing, and marketing of goods.
    • QFD was developed in 1972 at Mitsubishi’s Kobe shipyard site.
    • Xerox and Ford initiated the use of QFD in the United States in 1986.
  • 37. Quality Function Deployment
    • Chrysler also employed the QFD methodology in 1986 in the design and development of its LH-platform cars (Chrysler Concord, Eagle Vision, Dodge Intrepid). It used QFD along with concurrent engineering and utilization of design-for-manufacturing principles and design-of-experiments methods. The overall results were quite impressive: the design cycle took 36 months versus 54 to 62 months before; prototype cars were ready 95 days before the production lunch. Customer approval rating and sales have been very good.
  • 38. Manufacturability and Value Engineering
    • Main goals:
      • reduce complexity of products
      • Increase level of standardization among products
      • improve key functions of each product
      • improved job design and job safety
      • improved maintainability of the product
      • Green and ethical products
  • 39. Uncertainty in Product Design
    • Cost for develop a new product is high
    • The associated results, such as demand, competition, performance remain uncertain at the time decisions have to be made
    • Require OM tools to facilitate decision making in the early stage of product development
    • Decision Tree is one of the most popular tool

  • 41. Decision Tree Analysis
    • Decision tree analysis may be effectively used for strategic product decisions.
    • A decision tree contains:
    • Decision Nodes : from which one or several decisions alternatives can be chosen
    • Chance Nodes (state of nature): out of which one or several states of nature (events, outcomes) will occur
    • End Nodes : at the end of the decision tree, where payoffs are being developed
    • Arrows : that connect nodes and identify the sequence of decisions on the tree.
  • 42. Group Exercise: Introducing New Product
    • Construct the decision tree in detail
    • Identify the value of each node
    • Explain your decision making process
  • 43. Decision Tree Analysis
    • Analyzing new product introduction with decision trees involves following steps:
    • Define the problem.
    • Structure or draw the decision tree.
    • Assign probabilities to the Chance Nodes (states of nature).
    • Payoffs are calculated at the End Nodes
  • 44. Decision Tree Analysis
    • Estimate payoffs for each Chance Node by calculating the expected value over all alternatives and associated probability.
    • Solve the problem by working backwards, that is, starting at the right of the tree and working back to decision nodes on the left.
    • Identify the best alternative (decision) with the highest expected value.
  • 45. AgeTree Inc AgeTree, Inc. has developed a promising new product. The company’s management faces three choices: It can sell the idea of the new product to a company for $40,000, it can hire a consultant to study the market and then make a decision, or it can arrange financing for directly manufacturing the product. The study will cost AgeTree $25,000, and its management believes that there is about 2/3 of chances that a favorable market will be found. If the study is favorable, the company can sell the idea for $40,000, or it can manufacture the product. But even if a favorable market is found and the company manufactures the product, the chance of an ultimately successful production is about 60%. In this case, the company plans to sell 10,000 units of the product with a price of $50 each. The estimated fixed cost will be $190,000 and the variable cost will be $10 per unit. In case of unsuccessful results, the company will be able to sell approximately a half of its original number of units with the same price and costs. If the study is unfavorable, the management figures that it can still sell the idea for $40,000. Even with an unfavorable study, the company can still manufacture the product, but a successful product can be expected about once in every ten new-product introductions with the same results as those in case of the favorable study. If the AgeTree’s management decides to manufacture the product without the study, there is only a 1-in-4 chances of its being successful. The results will be exactly the same as previously mentioned.
