Resum	Transaction cost economics (TCE) analysis explains how firms should organize their economic exchanges -- whether to buy on the market, make in-house, or use a hybrid arrangement -- by minimizing the sum of production and transaction costs. Building on Coase's question of why firms exist, Oliver Williamson's 1979 article and 1985 book The Economic Institutions of Capitalism developed a comparative framework in which the efficient governance of a transaction depends on its attributes, above all asset specificity, together with uncertainty and frequency. Because human actors are boundedly rational and potentially opportunistic, contracts are inevitably incomplete; when a transaction requires investments specialized to a particular partner, those investments create quasi-rents that the partner can try to expropriate -- the hold-up problem. The central prescription, the discriminating-alignment hypothesis, is to match each transaction to the governance structure -- market, hybrid, or hierarchy -- that economizes on these transaction costs, making the make-or-buy decision a question of comparative institutional efficiency.	Strategic value chain analysis disaggregates a firm into the discrete activities through which it designs, produces, markets, delivers, and supports its product, in order to locate the sources of cost advantage and differentiation that underlie competitive advantage. The framework is Michael Porter's, introduced in his 1985 Competitive Advantage, where he divides the firm's activities into five primary categories — inbound logistics, operations, outbound logistics, marketing and sales, and service — and four support categories — firm infrastructure, human resource management, technology development, and procurement — with margin as the difference between total value created and total cost. Porter argued that competitive advantage cannot be understood by looking at the firm as a whole but must be traced to the way particular activities are performed and linked. The analysis extends outward to the value system linking suppliers, the firm, channels, and buyers.
