Historical Context
The concept of the value chain was first introduced by Michael Porter in his book “Competitive Advantage” published in 1985. Porter outlined the value chain as a systematic method for businesses to analyze their internal activities and identify opportunities for gaining competitive advantage.
Types/Categories of Activities
Primary Activities:
- Inbound Logistics: Activities related to receiving, storing, and disseminating inputs to the product (e.g., material handling, warehousing, inventory control).
- Operations: Transformation of inputs into final products (e.g., machining, packaging, assembly, maintenance).
- Outbound Logistics: Activities related to collecting, storing, and physically distributing the products to buyers (e.g., finished goods warehousing, order processing, transportation).
- Marketing and Sales: Activities to provide means by which buyers can purchase the product and are induced to do so (e.g., advertising, promotion, sales force, channel selection).
- Service: Activities to enhance or maintain the value of the product (e.g., installation, repair, parts supply, product adjustment).
Support Activities:
- Procurement: Purchasing inputs needed for the firm’s value chain (e.g., raw materials, supplies, and other consumable items).
- Technology Development: Includes research and development, product design, process improvement.
- Human Resource Management: Activities associated with recruiting, hiring, training, developing, and compensating all types of personnel.
- Firm Infrastructure: General management, finance, accounting, legal, government affairs, and quality management.
Key Events and Milestones
- 1985: Michael Porter introduces the value chain concept.
- 1990s: Value chain analysis becomes integral to the formulation of corporate strategies.
- 2000s: Integration of technology and IT systems enhances value chain analysis.
Detailed Explanation
Mathematical Models and Analysis
The value chain can be quantitatively analyzed using cost accounting and activity-based costing to determine the cost drivers at each stage. Key financial metrics include:
Analyzing these costs helps in understanding the efficiency and value creation of each stage in the value chain.
