PRODUCT AND SERVICE DESIGN
Characteristics of Product Design
Product design is essential to a company's survival and growth.
The development of new products is a costly and risky business.
The products produced by an organization should complement each other.
A foremost consideration in product design is the market of the product.
Most products have a life cycle -- introduction, growth, maturity, saturation, and decline.
Over 70% of the cost of a product is locked in at the end of the design phase.
The cost of identifying and eliminating a defect during production is ten times the cost during design. The cost is 100 times if the defect is identified after the product is sold to the customers.
Trends in Product and Service Design
Emphasis on customer satisfaction
Reduction of time between new product & service introduction
Improvement in process capability for new product & service
Emphasis on safety, legal, ethical and environment concerns
Simplification of product & service design
Product Strategies
1. Market Leader Strategy -- Strong in research and development.
2. Follow-the-Leader Strategy -- Strong in development and engineering; enter during growth stage.
3. Application-Oriented Strategy -- Strong in engineering; enter during growth or maturity stage.
4. Production Efficiency Strategy -- Strong in operations; enter during maturity or saturation stage.
Team Approach to Product Design (Concurrent Engineering, Simultaneous Engineering)
Experts from different functions (e.g., R&D, engineering, purchasing, accounting, manufacturing, marketing, etc.), as well as key suppliers and customers work together as a team throughout the product design and development process. This approach offers significant benefits to product design.
Consideration in Product Design
Standardization versus customization (delay differentiation, modular design)
Simplification versus suitability
Reliability
Robust design
Design for manufacturability/assembly
Design for recycling and design for disassembly
Design for remanufacturing
Component commonality
Types of Services
One way to classify the various types of services is to consider the extent of customer contact in the creation of services.
High Contact -- Health care, school, retail store
Medium Contact -- Repair shop, branch office of a bank
Low Contact -- Mail order service, postal service
* High-contact systems encounter more uncertainties about the operations.
* High-contact systems are usually less efficient than low-contact systems, but customers receive better services.
The second way to classify services is based on degree of labor intensity.
Capital Intensive -- telephone service, postal services.
Labor Intensive -- teaching, legal services.
The third way to classify services is based on variability in service requirements.
High variability – professional service, high-end hospitality service
Moderate variability – education, routine medical service
Low variability – mass service
Factors for Service-System Design
Efficiency versus sales opportunities
Service-System Design Alternatives

2. On-site technology
3. Phone contact
4. Face-to-face tight specifications
5. Face-to-face loose specifications
6. Face-to-face total customization
7. Internet
