Value chain analysis (VCA) is a method used to identify a company's potential sources of competitive advantage. It examines the range of activities involved in creating and delivering a product or service, including inbound logistics, operations, outbound logistics, marketing and sales, and services. VCA involves mapping a company's value chain, analyzing costs and differentiation within each activity, and comparing the company to competitors. The goal is to find ways to reduce costs or create greater customer value at each stage in order to strengthen competitive position.
