Ringkasan	Strategic group analysis partitions the firms in an industry into clusters that pursue similar strategies along key competitive dimensions, and explains why these clusters persist and why their members earn different returns. The concept originates with Michael Hunt's 1972 dissertation on the U.S. home-appliance industry and was given its theoretical engine by Caves and Porter's 1977 reconceptualization of entry barriers as mobility barriers — structural impediments that protect not just the industry from outsiders but each strategic group from incursion by firms in other groups. McGee and Thomas's 1986 review consolidated the construct, clarifying which variables legitimately define groups and how groups, mobility barriers, and isolating mechanisms relate to performance. The method bridges industrial-organization economics and strategic management by treating intra-industry structure, not just industry-level structure, as the relevant unit of competitive analysis.	The VRIN/VRIO resource audit is the operational test of the resource-based view of the firm: it examines a firm's resources and capabilities to judge which of them can be a source of sustained competitive advantage. Jay Barney's 1991 article established the criteria — a resource must be Valuable, Rare, Imperfectly imitable, and Non-substitutable (VRIN) — and later restated them as the VRIO question set, adding whether the firm is Organized to exploit the resource. Margaret Peteraf's 1993 cornerstones paper gave the same logic an economic grounding through resource heterogeneity, ex post and ex ante limits to competition, and imperfect mobility. Together they shifted strategy's attention inward, arguing that durable advantage comes less from industry position than from idiosyncratic, hard-to-copy resources. The audit walks each resource through these tests to classify its competitive implications.
