What is Value Chain Analysis? Porter’s Model, and Examples

Introduction To Value Chain Analysis

Understanding what is value chain analysis is essential for identifying how businesses create and sustain competitive advantage. At its core, value chain analysis is the process of examining a company’s activities—both primary and support functions—to determine where value is added and where improvements can be made. By breaking operations into distinct steps, businesses can better evaluate efficiency, reduce costs, and enhance differentiation in the marketplace.

The concept was first formalized by Michael Porter in 1985 through his Value Chain framework. Porter’s model explains how each stage of a company’s activities, from inbound logistics to after-sales service, contributes to delivering value to customers. This framework has since become a cornerstone in strategic management, helping organizations map out operations, identify strengths, and uncover opportunities for sustainable competitive advantage.

Why It Matters

• Provides clarity on how resources and processes generate value.
• Helps organizations pinpoint cost efficiencies and areas for innovation.
• Strengthens strategy by aligning activities with customer needs and expectations.

In short, value chain explained means understanding the interconnected activities that drive profitability and competitiveness. Businesses that effectively apply value chain analysis gain sharper insights into how to deliver value while optimizing internal performance.

Porter’s Value Chain Framework

The Porter Value Chain model, introduced by Michael Porter in 1985, breaks down a company’s activities into two categories: primary activities and support activities. Together, these activities illustrate how businesses create value for customers while maintaining cost efficiency and competitiveness.

Primary Activities

These are the core processes directly involved in delivering products or services:

• Inbound Logistics: Receiving, storing, and distributing raw materials.
• Operations: Transforming inputs into final products or services.
• Outbound Logistics: Warehousing, distribution, and delivery to customers.
• Marketing & Sales: Promoting products and persuading customers to buy.
• Services: Post-sale support, maintenance, and customer care.

Support Activities

These activities enable and enhance the effectiveness of primary functions:

• Firm Infrastructure: Finance, management, and legal systems.
• Human Resource Management: Recruitment, training, and retention of employees.
• Technology Development: Innovation, R&D, and process improvement.
• Procurement: Acquiring raw materials, equipment, and other resources.

Why Porter’s Model Matters

• Provides a structured way to analyze where value is created and costs are incurred.
• Helps businesses identify areas for efficiency improvements or differentiation.
• Remains one of the most widely used strategy tools in corporate strategy and competitive analysis.

Primary Activities in the Value Chain

The primary activities in the value chain are the core business processes directly responsible for creating and delivering value to customers. Michael Porter identified five key functions that every organization performs, regardless of industry. Understanding these value chain primary activities helps businesses optimize efficiency and strengthen competitive advantage.

1. Inbound Logistics

• Definition: Activities related to receiving, storing, and distributing raw materials or inputs.
• Examples: Supplier coordination, inventory management, and warehouse operations.
• Illustration: An automobile company managing just-in-time delivery of car parts from suppliers.

2. Operations

• Definition: The transformation of inputs into finished products or services.
• Examples: Manufacturing, assembly lines, packaging, or service delivery.
• Illustration: A bakery turning flour, sugar, and eggs into bread and pastries.

3. Outbound Logistics

• Definition: The processes involved in delivering finished products to customers.
• Examples: Warehousing, distribution channels, order fulfillment, and transportation.
• Illustration: An e-commerce retailer using logistics partners to ship orders within 24 hours.

4. Marketing & Sales

• Definition: Activities that make products and services attractive to customers and drive demand.
• Examples: Advertising campaigns, sales promotions, branding, and pricing strategies.
• Illustration: A smartphone company launching a new product through global marketing campaigns.

5. Service

• Definition: Post-sale activities that maintain or enhance product value.
• Examples: Customer support, warranty services, maintenance, and feedback handling.
• Illustration: A software company offering technical support and regular updates.

Why Primary Activities Matter

Each of these five steps in the value chain primary activities contributes directly to customer satisfaction and revenue generation.

2. Human Resource Management (HRM)

• Definition: Recruitment, training, development, and retention of employees.
• Examples: Talent acquisition, performance management, leadership development.
• Illustration: A consulting firm investing in staff training to improve client service delivery.

3. Technology Development

• Definition: Innovations and tools that improve products, services, or processes.
• Examples: Research & development (R&D), automation, data analytics, and digital platforms.
• Illustration: A manufacturer using robotics (support activity) to streamline operations (primary activity).

4. Procurement

• Definition: Acquiring raw materials, services, and resources required for production.
• Examples: Supplier selection, contract negotiation, and cost management.
• Illustration: A retail chain negotiating with suppliers to reduce costs and improve product margins.

Why Support Activities Matter

The support activities in the value chain don’t generate value directly, but they strengthen and enable primary processes. For example, technology development enhances operations through automation, while effective HRM ensures skilled staff deliver high-quality customer service. When optimized, these support functions can significantly increase efficiency, innovation, and profitability. Explore: Strategy Analysis Training Course
