The document discusses the concept of strategy according to Michael Porter. It argues that strategy is not about operational effectiveness or positioning, but rather creating a unique and valuable position through performing different activities than competitors or performing similar activities in different ways. This requires making trade-offs between activities to limit imitation. Sustainable strategy also relies on achieving fit across a company's activities to create reinforcing effects that are difficult for competitors to match. Rediscovering a company's original strategic position can allow it to better focus on areas of distinctiveness rather than attempting to compete more broadly.
