Design of goods & services
(Week 6)
Product Life Cycle
Introduction
R&D
Process modification & enhancement
Growth
Product design stabilize
Forecasting necessary capacity
Maturity
Established competitors
Need high volume, innovative production
Decline
Terminate useless products
Product By-Value analysis
In descending order, list products' individual dollar contribution to the firm.
Lists annual contribution of product.
Helps management evaluate alternate strategies
Manufacturability & Value Engineering
Reduce product complexity
Reduce environmental impact
Additional product standardization
Improved functional aspects
Improved job design & safety
Improved product maintainability
Robust design
Issues for product development
Robust Design
Designed so that small variations on production do not adversely affect the product
Results in lower cost and higher quality
Modular Design
Product designed in easily segmented components
Flexibility by production and marketing
Computer Aided Design (CAD)
Shorter development cycles, improved accuracy, lower cost
Computer Aided Manufacturing (CAM)
Use programs to control manufacturing equipment
Better product quality
Shorter design time
Production cost reduction
New range of capabilities
Virtual Reality Technology
Allows people to see finished design before physical model is built
Effective in large scale designs
Value Analysis
Focus on design improvement during production
Environmentally Friendly Design
Life Cycle Assessment (LCA)
Enhance productivity and deliver goods in environmentally and ethically responsible manner
Conservation and renewal of resources through the entire product life cycle:
Design
Production
Destruction
Product documents
Bill of material
Engineering drawing
Group technology
Documents for Production
Assembly Drawing
Exploded view of products
Assembly Chart
Identifies point of production where components flow into subassemblies and into final product
Route Sheet
List operations and times required to produce a component
Work Order
Instructions to produce a quantity of items, usually to a schedule
Engineering Change Notices (ECN)
Correction / modification to product's definition / documentation
Moments of Truth
Critical moments between customer & organisation that determine customer satisfaction
