2. Types of Processes Conversion
iron ore into steel
Fabrication
forming raw material (gold into jewelry)
Assembly
fastening parts together to create product (bicycle)
Testing
for quality of products
3. Process Flow Structures Job shop (ex. Copy center making a single copy of a student term paper)
Batch (standardized job shop) (ex. Copy center making 10,000 copies of an ad piece for a business)
Assembly Line
Continuous Flow
5. Process Flow DesignDefined A process flow design can be defined as a mapping of the specific processes that raw materials, parts, and subassemblies follow as they move through a plant.
The most common tools to conduct a process flow design include assembly drawings, assembly charts, and operation and route sheets.
6. Process Flow Design Assembly drawing (see Exhibit 6.5)
an exploded view of the product
Assembly chart (Gozinto) (Exhibit 6.6) defines how parts go together
Operation and route sheet (Exhibit 6.7) specifies operations and routing
Flow Process Chart (see Exhibit 6.8)
uses standard symbols to show what happens to product as it flows through production process
8. Example: Assembly Chart (Gozinto)

15. Benefits from Adopting New Technologies Labor costs
Material costs
Inventory costs
Transportation or distribution costs
Quality costs
16. Other Benefits…. Increased product variety
Improved product features and quality
Shorter cycle times
17. Risks Technological risks
Organizational risks
Environmental risks
Market risks
18. Global Product Design and Manufacturing Joint Ventures
Strategic Suppliers
Global Product Design Strategy
19. Virtual Factory Shift from centralized production to ...... an integrated network of capabilities
local, national, global
20. “The best engineered part is no part” NCR has achieved or overcome the following:
less components
less suppliers
less assembly time
eliminating screws and fasteners
faster speed of concept to market
lower costs
21. Product Development in Japan - Benefits Employment throughout the economy
easy to make design changes
many small innovative companies
22. Product Development in Japan - weaknesses Very complex structure of companies
difficult to understand
difficult to control
a breakdown in a small company could immobilize a large company like Matsushita.
