  • Operations Management Product Design Chapter 3 OPM 533 3-
    • Product design involves designing a product that can be produced and marketed profitability.
    • The basis of an organization’s existence is the good or service it provides society.
    • Great products are key to success.
    • Top organizations typically focus on core products
    • Customers buy satisfaction, not just a physical good or particular service
    • The objective of product decision is to develop and implement a product strategy that meets the demand of the marketplace with a competitive advantage
    Product Decision? OPM 533 3-
  • Product Strategy Options
    • Product differentiation
    OPM 533 3-
    • Low cost
    • Rapid response
  • Product Life Cycle
    • Products are born.
    • They live and they die.
    • Product life cycle can be divided into four stages:
    • i) Introduction
    • ii) Growth
    • iii) Maturity
    • iv) Decline
    OPM 533 3-
  • Product Life Cycle Introduction
        • Fine tuning
          • research
          • product development
          • process modification and enhancement
          • supplier development
    OPM 533 3-
  • Product Life Cycle Growth
    • Product design begins to stabilize
    • Effective forecasting of capacity becomes necessary
    • Adding or enhancing capacity may be necessary to accommodate the increase in product demand.
    OPM 533 3-
  • Product Life Cycle Maturity
    • Competitors are now established
    • High volume, innovative production may be needed
    • Improved cost control, reduction in options, paring down of product line m ay be required to maintain profitability and market share.
    OPM 533 3-
  • Product Life Cycle Decline
    • Product life is at an end.
    • Unless product makes a special contribution to the firm’s reputation or can be sold with high contribution, their production must be terminated.
    OPM 533 3-
  • Product Life Cycle, Sales, Cost, and Profit OPM 533 3- Sales, Cost & Profit . Introduction Maturity Decline Growth Cost of Development & Manufacture Sales Revenue Time Cash flow Loss Profit
  • Product-by-Value Analysis
    • Effective operations manager select items that show the greatest promise.
    • Product-by-value analysis lists products in descending order of their individual dollar contribution to the firm.
    • Also lists the total annual contribution of the product
    • It helps management evaluate possible strategies for each product.
    • It also tells management which products should be eleminated,
    OPM 533 3-
  • New Product Opportunities Brainstorming is a useful tool to generate new product ideas.
    • Understanding the customer
    • Economic change
    • Sociological and demographic change
    • Technological change
    • Political/legal change
    • Market practice, professional standards, suppliers, distributors
  • Product Development Stages
    • Idea generation
    • Assessment of firm’s ability to carry out idea
    • Customer Requirements
    • Functional Specification – how the product will work?
    • Product Specifications – how the product will be made?
    • Design Review – Are the product specifications the best to meet customers requirements?
    • Test Market – Does product meets customers expectation?
    • I ntroduction to Market
    • Evaluation – success or fail?
    OPM 533 3-
  • Quality Function Deployment
    • Quality Function Deployment (QFD) refers to :
    • i) identifying what will satisfy customer
    • ii) translate it into the target design
    • The idea of QFD is to understand what customer wants and to identify alternative process solutions.
    • QFD is used early in design process to help determine what will satisfy the customer and where to deploy quality efforts.
    OPM 533 3-
  • Quality Function Deployment
    • One of the tools of QFD is the house of quality.
    • House of quality is a graphic technique for defining the relationship between customers desires and product or service.
    • There are 7 steps to build house of qualit y.
    OPM 533 3-
  • 7 Steps to built house of quality
    • Identify customer wants
    • Identify how the good/service will satisfy customer wants
    • Relate customer wants to product hows
    • Identify relationships between the firm’s hows
    • Develop importance ratings
    • Evaluate competing products
    • Determine the desirable technical attributes, company’s performance and competitors performance.

  • Organizing for Product Development
    • Historically – distinct departments
      • Duties and responsibilities are defined
      • Difficult to foster forward thinking
    • Today – team approach
      • Representatives from all disciplines or functions
      • Concurrent engineering – cross functional team

    • Critical moments between the customer and the organization that determine customer satisfaction
    • There may be many of these moments
    • These are opportunities to gain or lose business
  • Moments-of-Truth Computer Company Hotline Figure 5.13 The technician was sincerely concerned and apologetic about my problem He asked intelligent questions that allowed me to feel confident in his abilities The technician offered various times to have work done to suit my schedule Ways to avoid future problems were suggested Experience Enhancers Only one local number needs to be dialed I never get a busy signal I get a human being to answer my call quickly and he or she is pleasant and responsive to my problem A timely resolution to my problem is offered The technician is able to explain to me what I can expect to happen next Standard Expectations I had to call more than once to get through A recording spoke to me rather than a person While on hold, I get silence,and wonder if I am disconnected The technician sounded like he was reading a form of routine questions The technician sounded uninterested I felt the technician rushed me Experience Detractors
  • Documents for Services
    • High levels of customer interaction necessitates different documentation
    • Often explicit job instructions for moments-of-truth
    • Scripts and storyboards are other techniques
  • Improving Customer Relations at a Drive-up Window
    • Be especially discreet when talking with customer through the microphone
    • Provide written instructions for customers who must fill out forms you provide
    • Mark lines to be completed or attach a note with instructions
    • Always say ”please” and “thank you”
    • Establish eye contact with the customer if the distance allows it
    • If the transaction requires that the customer park the car and come into the lobby, apologize for the inconvenience.

  • Transition to Production
    • Know when to move to production
      • Product development can be viewed as evolutionary and never complete
      • Product must move from design to production in a timely manner
    • Most products have a trial production period to insure producibility
    • Responsibility must also transition as the product moves through its life cycle
