“Product development is
|
the set of activities beginning with the perception of a market opportunity and ending in the production, sale, and delivery of the product”
|
|
Product Development Strategy
|
Task: Define a well-defined product development process and propose a product development organization that will allow your company to compete effectively over the next decade.
|
|
A Generic Product Development Process
|
|
|
Phase 0
|
Planning
Generate mission statement (target market, business goals, key assumptions and constraints) |
|
Phase 1
|
Concept dev
Identify needs of target market; Select several product concepts for further development and testing |
|
Phase 2
|
System-level Design
Define product architecture Decompose product into subsystems and components Define final assembly scheme |
|
Phase 3
|
Detail Design
Complete specification of geometry, materials and tolerances of all parts List of standard parts to be purchased Detailed drawings Process plans for fabrication and assembly |
|
Phase 4
|
Testing and Refinement
Building of alpha- and beta- prototypes alpha: same material and geometry - does it work? - does it satisfy customer needs? beta: parts supplied by production process - tested internally and by customers - tested for performance and reliability |
|
Phase 5
|
Production Ramp-Up
Small volume production to train workforce and work out any remaining problems. AND FINALLY LAUNCH |
|
Variations to Product Development Process
|
Market pull products
Market opportunity to technology, e.g. sporting goods, furniture Uses generic process Technology push products Technology to market opportunity, e.g. teflon, gore-tex Concept development takes technology as given Platform products Built around existing platform, e.g. consumer electronics, printers Concept development assumes proven technology platform Process intensive products Product constrained by production process, e.g. semiconductors, chemicals Product and process developed from start Quick build products Rapid modeling and prototyping, e.g. software, cell phones Many design-build-test cycles Complex systems System includes many subsystems and components, e.g. airplanes, jet engines System and subsystems developed by many teams working in parallel |
|
What drives product development costs?
|
Late changes – parts being scrapped, customer satisfaction issues, brand image damaged,potential recalls, may need overtime to meet deadlines
|
|
Quality Function Deployment (QFD)
|
A method to translate customer requirements into engineering specifications
Aims to get design, engineering and production people involved early on in the process to avoid late design changes that drive up cost |
|
Emerging Paradigms in Product Development
|
Green design (inspired by “bio-logic”)
Rule #1: Use a parsimonious palette Simplify & go natural Rule #2: Cycle up Use recyclable materials Avoid “monstrous hybrids” Rule #3: Exploit the power of platforms Use the same components and the same materials across product lines |
|
How to implement Green design ?
|
Using toxic material screens
Choosing materials that can be upcycled Choosing materials that are cost-effective to recycle Integrating these considerations into the design process Exploiting economies of scale & reducing inputs Rethink the buyer-supplier relationship |
|
Variability hurts!
|
With limited WIP, production variability reduces the effective throughput rate (capacity) of the system.
|
|
Why does variability occur?
|
Machine and human variations, errors, raw material quality problems,
|
|
What’s the solution to variability?
|
Increase inventory; Disadvantage: costly
Reduce variability; e.g. Toyota Production System |
