概要	Strategic Orientation refers to the fundamental approach an organization adopts when competing in its market, encompassing its competitive strategy, market focus, and organizational design. Miles and Snow's (1978) foundational framework identifies four strategic postures: Defenders (focus on stable market segments, operational efficiency, and incremental innovation), Prospectors (pursue new market opportunities, drive innovation, accept higher risk), Analyzers (balance efficiency and innovation, serve established markets while exploring adjacent opportunities), and Reactors (lack clear strategy, respond reactively to environmental pressures). This scale operationalizes Miles and Snow's framework, revealing an organization's strategic type and fit with its environment and structure.	Innovation Ambidexterity—the organizational capacity to simultaneously engage in exploration (pursuing radical, novel innovations) and exploitation (improving and extending existing products and processes)—is fundamental to sustained competitive advantage. March (1991) formalized this trade-off in Organization Science, arguing that organizations must balance the two to survive and thrive. Exploration alone leads to variety but insufficient returns; exploitation alone leads to competence traps and vulnerability to disruption. This scale, operationalized by He and Wong (2004) and extended by Jansen et al. (2006), measures organizational capability in both domains and the degree to which firms balance competing innovation imperatives.
