Vertical integration is a strategic management concept that involves a company taking control of more than one stage of the supply chain. This can be done by acquiring or building companies that provide goods or services at different stages of production, or by developing in$-$house capabilities to provide these goods or services.

Vertical integration can be a powerful tool for companies looking to gain a competitive advantage, as it allows them to control their supply chain and ensure that their products or services are of the highest quality.

Diversification involves a company expanding its operations into new markets or industries that are related to its existing business. This can be done through acquisitions, joint ventures, or new product development, and can help companies to reduce risk and expand their customer base.

Geographic competition, finally, is a strategic management concept that involves companies competing for market share in specific regions or markets. This can be done through a variety of means, including marketing, product development, and pricing strategies, and can be a powerful tool for companies looking to expand their customer base and market share.

Final answer: Overall, these strategic management concepts can be used to guide our discussion of vertical integration, diversification, and geographic competition, and can help companies to make informed decisions about how to expand their operations and compete in the market.
