Michael Porter’s Value Chain

E-Commerce Value added
Disintermediation
Shifting value adding activities
Push vs. Pull

Global

Global Highly centralized information system
Subsidiaries have little autonomy
Sometimes called a “franchiser”
Extensive communication network necessary
Difficult and impractical
Heavy reliance on headquarters for new products and ideas
Examples:
McDonald’s, Mrs. Fields’ Cookies, General Motors

Multinational

Multinational Production, sales, and marketing are decentralized
Financial management remains the parent’s responsibility
Example: Tyco Corporation
Focus on local responsiveness
Reduces the need for communication between subsidiaries and headquarters
Each subsidiary operates on a different platform

International

International Operates much like a multinational corporation
But subsidiaries depend on headquarters more for process and production decisions
Information systems personnel are regularly exchanged among locations
Encourages a cooperative culture in geographically dispersed personnel
Example: Caterpillar Corporation

Exhibit 9.4 A Transnational Structure

Transnational Parent and all subsidiaries work together in designing policies, procedures, and logistics
Usually focuses on optimizing supply sources and using advantages available in subsidiary locations
Architecture requires a higher level of standardization and uniformity for global efficiency
But must maintain local responsiveness
Examples: Citigroup, Sony, Ford
