The document discusses different strategies for business growth and expansion, including vertical integration, horizontal integration, related diversification, and unrelated diversification. Vertical integration involves extending a firm's activities backward into supplying raw materials or components, or forward into downstream markets. Horizontal integration means entering new, closely related businesses using similar processes, technologies, or markets. Related diversification adds new products or markets related to the core business, while unrelated diversification expands into areas without direct connections to the existing business.
