Unit 1: Introduction to Global Supply Chains

Introduction to Global Supply Chains

A Global Supply Chain (GSC) refers to the network of suppliers, manufacturers, warehouses, logistics providers, and distribution channels that operate across multiple countries to produce and deliver goods or services to customers worldwide.

It involves cross-border flows of:

• Materials
• Information
• Money
• Finished products

A global supply chain integrates activities from raw material sourcing to final delivery, often using international suppliers, manufacturers, and distribution networks.

Scope of Global Supply Chains

The scope of GSCs is broad and includes:

a) Geographical Scope

• Operations spread across multiple countries
• Global procurement, manufacturing, and distribution

b) Functional Scope

• Planning
• Sourcing
• Production
• Logistics
• Warehousing
• Distribution
• Customer service

c) Strategic Scope

• Aligning supply chain decisions with business strategy
• Managing global risks (currency, political, natural disasters)
• Ensuring cost efficiency and timely delivery

d) Technological Scope

• Digital tools: ERP, IoT, AI, blockchain
• Global tracking and visibility systems

Evolution of Global Supply Chains

Global supply chains have evolved over many decades due to changes in market needs and technology.

a) Early Trade Era (Pre-1900s)

• International trade began via ships, silk routes
• Simple supply chains based on barter and traditional trade

b) Industrial Revolution (1900–1970s)

• Rise of mass production
• Mechanized factories increased global trade
• Better transportation (railways, steamships)

c) Globalization Era (1980–2000)

• Companies started outsourcing and offshoring
• Global markets opened (WTO formation)
• Low-cost manufacturing countries (China, India, Vietnam) became hubs

d) Digital Supply Chain Era (2000–Present)

• Use of automation, robotics, AI, cloud computing
• Real-time visibility across borders
• E-commerce giants like Amazon changed customer expectations

e) Post-COVID & Resilience Era (2020 onwards)

• Focus on supply chain resilience
• Nearshoring, friend-shoring, diversification of suppliers
• Emphasis on sustainability and risk management

Key Components of Global Supply Chains

Global supply chains consist of five major components:

---

1) Sourcing (Procurement)

This includes finding and selecting suppliers worldwide.

Key activities:

• Identifying global suppliers
• Evaluating supplier capability and cost
• Negotiating prices and contracts
• Ensuring quality standards
• Ethical and sustainable sourcing

Importance: Helps reduce cost, access better technology, and maintain flexibility.

2) Manufacturing (Production)

This refers to where and how goods are produced.

Types of manufacturing strategies:

• Offshoring (production in low-cost countries)
• Nearshoring (production closer to demand)
• Contract manufacturing (outsourcing to companies like Foxconn)

Decisions include:

• Plant location
• Capacity planning
• Production scheduling

Importance: Manufacturing choices impact cost, quality, speed, and customer satisfaction.

3) Logistics

Movement of materials and products from one country to another.

Covers:

• Transportation (air, ocean, rail, road)
• Freight forwarding
• Customs clearance
• Warehousing

Importance: Ensures timely, safe, and cost-effective movement across borders.

4) Distribution

Ensures delivery of finished products to the final customer.

Includes:

• Managing global distribution centers
• Last-mile delivery
• Inventory management
• Channel selection (retailers, wholesalers, e-commerce)

Importance: Fast and reliable distribution increases customer satisfaction and brand loyalty.

5) Customers

The final part of a global supply chain.

Includes:

• Retail customers
• Business buyers
• Global markets

Customer demands influence:

• Product design
• Delivery speed
• Customization
• Sustainability

Importance: Customer expectations shape supply chain strategy.

Importance and Strategic Role of Global Supply Chains

Global supply chains are not just operational systems—they are a source of competitive advantage.

a) Cost Efficiency

• Access to cheaper labor
• Lower manufacturing costs
• Economies of scale

Example: Apple manufactures in China to reduce cost while maintaining quality.

b) Access to Global Talent & Technology

Companies can utilize the best suppliers and technology providers worldwide.

c) Faster Market Reach

Global networks allow companies to supply products quickly to multiple regions.

d) Flexibility & Agility

Ability to switch suppliers, reroute shipments, or shift production when disruptions occur.

e) Innovation & Collaboration

Global supply partners share knowledge, ideas, and new technologies.

f) Improved Customer Service

Faster, more reliable international distribution improves customer satisfaction.

g) Risk Diversification

Spreading operations across multiple countries reduces dependence on one region.

h) Sustainability & Responsibility

Modern global supply chains focus on:

• Ethical labour
• Eco-friendly materials
• Carbon footprint reduction

This improves brand image and compliance.

Conclusion

Global Supply Chains are a complex but essential part of modern business.
For MBA students, understanding GSCs is crucial because companies today operate in interconnected global networks. A well-managed supply chain improves efficiency, reduces cost, enhances customer satisfaction, and creates long-term competitive advantage.

Supply Chain Flows

In any supply chain, four major flows move continuously between suppliers, manufacturers, distributors, retailers, and customers.

---

A) Product Flow

This refers to the physical movement of goods from suppliers to customers.

Includes:

• Raw materials → manufacturers
• Components → assembly plants
• Finished goods → distributors/retailers
• Home delivery to customers

Key Focus Areas:

• Transportation
• Warehousing
• Inventory management
• Packaging

Goal: Deliver the right product at the right time, in the right quantity, and at minimum cost.

B) Information Flow

This flow consists of data and communication related to orders, delivery status, forecasting, payments, and inventory.

Includes:

• Purchase orders
• Sales data
• Tracking information
• Forecasting and planning

Importance:

• Enables coordination across global partners
• Improves efficiency and reduces uncertainty

Technologies used: ERP, IoT, Blockchain, RFID, Cloud Systems.

C) Financial Flow

This represents movement of money across the supply chain.

Includes:

• Payments to suppliers
• Credit terms
• Cash flow management
• Duties and taxes
• Financial settlements across borders

Importance: Ensures all parties are paid and financial risks are minimized.

D) Reverse Flow (Reverse Logistics)

This is the movement of products backward from customers to sellers or manufacturers.

Includes:

• Product returns
• Recycling
• Repair and refurbishment
• Warranty claims
• Disposal of damaged goods

Importance: Improves sustainability, customer satisfaction, and cost recovery.
