48
Primary objective of supply base management and supplier development processes
Continuous improvement and growth of supplier capabilities
49
Supplier Performance Index (SPI)
evaluates suppliers by identifying and quantifying total cost of doing business, as the lowest purchase price may not always result in the lowest total cost for an item
50
SPI Equation
SPI = Total purchases + Nonperformance cost / Total purchases
51

52
Global Sourcing
Integrating and coordinating common items, sourcing strategies and suppliers across worldwide purchasing and operating locations
53
Why source Worldwide?
- Cost/price benefits - Access to product / process technology - Introduce competition to domestic suppliers - React to buying patterns of competitors - Establish a presence in a foreign market
54
Incoterms
Define responsibilities of buyer/seller transportation
55
