- Value Chain
- The full sequence of activities a firm performs to design, produce, market, deliver, and support its product or service.
- Primary Activities
- The five core operational activities in Porter's model that directly create and deliver a product: inbound logistics, operations, outbound logistics, marketing and sales, and service.
- Support Activities
- The four enabling activities β firm infrastructure, human resource management, technology development, and procurement β that underpin all primary activities.
- Margin
- In value chain terms, the difference between the total value created for the customer and the total cost of performing all activities.
- Competitive Advantage
- A structural benefit β lower cost or differentiated output β that one firm achieves in a specific activity relative to rivals.
- Cost Driver
- Any factor that causes the cost of an activity to increase or decrease β such as scale, capacity utilization, location, or learning curve effects.
- Differentiation Driver
- Any factor that causes a firm's output to be perceived as more valuable than competitors' β such as quality, speed, reliability, or unique features.
- Linkage
- An interdependency between two value chain activities where the cost or performance of one affects the other β optimizing linkages is a key source of competitive advantage.
- Outsourcing
- Delegating a value chain activity to an external supplier, typically when that activity is not a source of competitive advantage and can be performed more cheaply externally.
- Value System
- The broader network of value chains β suppliers, the firm, distributors, and buyers β that together create and deliver the final product to the end customer.
