The document discusses several papers related to business models and strategy. It argues that a business model is an abstraction of a firm's strategy, depicting how it creates and captures value. Strategy determines the business model options available and business models guide tactical decisions. Later papers integrate these concepts, stating that strategy determines the business model, which then defines available tactics. Together, strategy, business models, and tactics allow firms to achieve their goals but business models must also be difficult to imitate to provide competitive advantage.
