1. Chapter 4 Product and Service Design

2. 4-2 Typical Phases of Product Development • Planning • Concept Development • System-Level design • Design Detail • Testing and Refinement • Production Ramp-up

3. 4-3 Economic Analysis of Project Development Costs • Using measurable factors to help determine: • Operational design and development decisions • Go/no-go milestones • Building a Base-Case Financial Model • A financial model consisting of major cash flows • Sensitivity Analysis for “what if” questions

4. 4-4 Value Analysis/ Value Engineering Quality Function Deployment Designing for the Customer House of Quality Ideal Customer Product

5. 4-5 Designing for the Customer: Quality Function Deployment • Interfunctional teams from marketing, design engineering, and manufacturing • Voice of the customer • House of Quality

7. 4-7 Designing for the Customer: Value Analysis/Value Engineering • Achieve equivalent or better performance at a lower cost while maintaining all functional requirements defined by the customer • Does the item have any design features that are not necessary? • Can two or more parts be combined into one? • How can we cut down the weight? • Are there nonstandard parts that can be eliminated?

8. 4-8 Design for Manufacturability • Traditional Approach • “We design it, you build it” or “Over the wall” • Concurrent Engineering • “Let’s work together simultaneously”

9. 4-9 Measuring Product Development Performance Measures Performance Dimension • Freq. Of new products introduced • Time to market introduction • Number stated and number completed • Actual versus plan • Percentage of sales from new products Time-to-market • Engineering hours per project • Cost of materials and tooling per project • Actual versus plan Productivity • Conformance-reliability in use • Design-performance and customer satisfaction • Yield-factory and field Quality
