Product and Service Design With Computation of Reliability 1 2  1. Cost 2. Quality Major Factors in Design 3. Time-to-market Strategy 4. Customer satisfaction 3 5. Competitive advantage  Sources of Ideas for New or Redesigned Products and Services 1. Internal Sources Research & Development (R&D) - Organized efforts to increase scientific knowledge or product innovation. Idea 2. External Sources Generation -customers -suppliers -competitors *reverse engineering - dismantling and 4 inspecting a competitor’s product to discover product improvements.  1. Product / Service Life Cycle -Incubation, growth, maturity, saturation, and decline. 2. Standardization Design -Extent to which there is an absence of Consideration variety in a product, service or process. s -Standardized products are immediately available to customers *Mass Customization - a strategy of producing standardized goods or services but incorporating some degree 5 of customization.  Tactics in Mass Customization: a. Delayed differentiation - is a postponement tactic, producing but not quite completing a product or service until customer preferences or specifications are Design known. Consideration b. Modular design - a form of s standardization in which component parts are subdivided into modules that are easily (continuation) replaced or interchanged. It allows: -easier diagnosis and remedy of failures 6 -easier repair and replacement -simplification of manufacturing and assembly  3. Reliability - the ability of a product, part, system to perform its intended function under a prescribed set of condition. Design *failure – situation in which a product, part, or system does not perform as Consideration intended. s *normal operating conditions – set (continuation) of conditions under which an item’s reliability is specified. 4. Robust Design - design results in 7 products or services that can function over a broad range of condition.  1. Concurrent Engineering - bringing together of engineering design and manufacturing personnel early in the design phase. Designing 2. Computer-Aided Design (CAD) – designing products using computer for graphics. Production -increases productivity of designers, 3 to 10 times -creates a database for manufacturing information on product specifications -provides possibility of engineering and 8 cost analysis on proposed designs  3. Recycling - recovering materials for future use. Reasons for recycling: Cost savings Designing for Environment concerns Manufacturin g Environment regulations (continuation ) 4. Remanufacturing - refurbishing used products by replacing worn-out or defective components. 9  Independent events - events whose occurrence or Reliability nonoccurrence do not influence each other. 10 Redundancy - the use of backup components to increase reliability.  If two or more events are independent and success is defined as the probability that all these events occur, then the probability of success is equal to Rule # 1 the product of the probabilities of the events. Lamp 1 Lamp 2.90.80.90 x.80 =.72 11  If two events are independent and success is defined as the probability that at least one of the events will occur, the probability of success is equal to the probability of either one plus 1.00 minus Rule # 2 the probability multiplied by the other probability..80 Lamp 2 (backup) 12.90.90 + (1-.90) x.80 =.98  If three events are involved and success is defined as.70 the probability that at least one of them occurs, the probability of success is equal to the probability of the first one (any of the.80 Rule # 3 events), plus the product of 1.00 minus that probability and the probability of the second event (any of the.90 remaining events), plus the product of 1.00minus each of the first two probabilities and the probability of the 1-[(1-.90)*(1-.80)*(1-.70)] =.994 13 third event, and so on. This rule can be expanded to  Compute for the total system reliability.70.79.80.85.80 14.92.90.92.93.89.70.70.85.80.90.92.92.93.89 15  Formative Assessment Write a short essay. Think of a product or service that you would want to redesign. Explain your choice. 16 Thank You!
