1 — 22 • Product Development Process • Economic Analysis of Development Projects • Designing for the Customer • Design for Manufacturability • Measuring Product Development Performance. OBJECTIVES
1 — 33 Typical Phases of Product Development: Example of Marketing Function • Planning – Articulate market opportunities – Define market segment • Concept Development – Collect customer needs – Identify lead users – Identify competitive products • System-Level design – Develop plan for product options & extended product family – Set target sales price points • Design Detail – Develop marketing plan • Testing and Refinement – Develop promotion & launch materials – Facilitate field testing • Production Ramp-up – Place early production with key customers
1 — 44 Economic Analysis of Project Development Costs • Using measurable factors to help determine: – Operational design and development decisions • should we outsource in order to save time? – Go/no-go milestones • should we develop to address new mkt opportunity? • Building a Base-Case Financial Model – Estimating time & amount of cash flow to determine Net Present Value of the cash flow – A financial model consisting of major cash flows • e. g costs: development, marketing & unit production – Sensitivity Analysis for “what if” questions • Calculate changes in NPV vs. changes in factors in model

1 — 22 22 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?
1 — 23 23 Design for Manufacturability • Traditional Approach – “ We design it, you build it” or “Over the wall” • Concurrent Engineering – “ Let’s work together simultaneously”
1 — 24 24 Design for Manufacturing and Assembly Greatest improvements related to DFMA arise from simplification of the product by reducing the number of separate parts : 1. During the operation of the product, does the part move relative to all other parts already assembled? 2. Must the part be of a different material or be isolated from other parts already assembled? 3. Must the part be separate from all other parts to allow the disassembly of the product for adjustment or maintenance?
1 — 25 25 Designing Service Products Unlike manufacturing products, service products involves customer directly and can be complicated during its process, impacting both time and knowledge to serve customer Factors affecting service design: • Service Experience Fit : New service fit into currently provided services. E. g. Movie & Selling Pop-corns • Operational Fit : Collaborate with other operational skills in to service customer. E. g. Retail store & Home Delivery • Financial Fit : Is it financially justified ? May be necessary to retain customer.
1 — 26 26 Measuring Product Development Performance Measures • 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 Productivity Quality • Engineering hours per project • Cost of materials and tooling per project • Actual versus plan • Conformance-reliability in use • Design-performance and customer satisfaction • Yield-factory and field.
