Value Chain
Definition
The value chain is the full set of activities a company performs to create and deliver value to customers, from inbound logistics and operations through marketing, delivery, and after-sales service. The concept was introduced by Michael Porter.
In Practice
Porter's framework splits activities into primary ones (inbound logistics, operations, outbound logistics, marketing and sales, service) and support ones (procurement, technology, human resources, firm infrastructure). Analyzing each activity's cost and its contribution to what customers pay reveals where margin is actually created or destroyed.
For supply chain professionals, value chain thinking widens the lens beyond cost. The supply chain is not just a cost center to squeeze; it can be the source of competitive advantage, as with a retailer whose replenishment speed lets stores carry fresher assortments, or a manufacturer whose delivery reliability wins contracts at premium prices. The question shifts from "how cheap" to "which capabilities differentiate us."
Value chain analysis also guides make-versus-buy choices: activities where you add distinctive value stay in-house, while generic ones become candidates for outsourcing. A specialty coffee brand may outsource warehousing yet keep roasting in-house, because roasting is where its value is created.
