Value Chain Analysis: Identifying Activities, Costs, and Competitive Advantage

Value is the key to business success; delivering value to customers increases acquisition, retention, and advocacy, which in turn raises profit and profitability.

Value chain analysis examines the set of activities a company performs to deliver valuable products or services to customers, helping determine whether each activity creates more value than it costs.

Originally proposed by Michael Porter in 1985, the value chain consists of nine profit‑impacting activities divided into primary and support categories.

Primary activities: inbound logistics, operations, outbound logistics, marketing & sales, and service.

Support activities: procurement, technology development, human resource management, and firm infrastructure.

Analyzing the value chain can uncover competitive advantage through two strategies: cost advantage—identifying cost drivers and reducing expenses to maximize profit margins, and differentiation—highlighting unique product or service attributes that increase perceived value and allow premium pricing.

The analysis can be performed in three steps: (1) identify all primary and support activities within the value chain; (2) determine the cost and value contribution of each activity; and (3) pinpoint activities that offer the greatest opportunities for cost‑saving or differentiation, thereby creating a sustainable competitive edge.
