Systematically decompose a firm or industry into strategically relevant activities to understand where value is created and where profit concentrates. Based on Michael E. Porter's framework from Competitive Advantage (1985).
Activities directly involved in creating and delivering the product:
ActivityDescriptionKey QuestionsInbound LogisticsReceiving, warehousing, inventory control of inputsHow efficiently are inputs sourced and managed?OperationsTransforming inputs into final product/serviceWhat is the cost structure? Where are quality bottlenecks?Outbound LogisticsDistributing product to buyersHow does delivery affect customer experience and cost?Marketing & SalesBuyer awareness, persuasion, channel selectionWhat drives customer acquisition cost? Brand premium?ServicePost-sale support, maintenance, warrantiesDoes service create loyalty, upsell, or lock-in?
Activities that enable and improve primary activities:
ActivityDescriptionKey QuestionsFirm InfrastructureGeneral management, planning, finance, legalDoes governance enable or hinder agility?Human Resource ManagementRecruiting, training, retention, compensationAre talent capabilities a competitive advantage?Technology DevelopmentR&D, process automation, IT systemsDoes technology reduce cost or enable differentiation?ProcurementPurchasing inputs, negotiating supplier termsDoes procurement scale drive cost advantage?
Porter extended the value chain into a value system — the linked chains of all players:

Supplier Value Chain → Firm Value Chain → Channel Value Chain → Buyer Value Chain
Analyze where margin accumulates across the entire system. In many industries, profit concentrates in a few nodes (e.g., chip design vs. manufacturing, brand owners vs. contract manufacturers).
