Porter's decomposition of a firm into discrete activities — primary and support — that reveals where value is created, where costs are incurred, and where opportunities for differentiation reside.
The value chain framework analyzes firms by breaking them into discrete value-adding activities: primary activities (inbound logistics, operations, outbound logistics, marketing and sales, service) and support activities (firm infrastructure, human resource management, technology development, procurement). Porter's insight was that competitive advantage cannot be understood by looking at the firm as a whole; it must be located in specific activities and in the linkages among them. A firm achieves cost advantage by performing activities more efficiently than competitors. It achieves differentiation by performing activities in ways that create unique value. The framework makes the invisible visible — revealing where strategic opportunities actually exist rather than where intuition suggests they should.

For knowledge-work firms, the traditional value chain categories (logistics, manufacturing, distribution) map imperfectly. The Porter simulation proposes a more precise decomposition: conception, research, generation, evaluation, revision, and distribution. This sequence functions as the value chain of the AI economy. Conception determines what should be built. Research gathers the information that
