In the search to increase revenues and attract more clients to achieve a greater economic benefit, companies seek to expand into international markets. This process of expansion is known as internationalization. Internationalization presents several forms or modes of entry of companies to the international market, among which we have exports, contractual agreements, strategic alliances and direct foreign investment. For the entry of companies into foreign markets, models or structures have been developed that explain this process, among the most recognized and studied we have the Uppsala model, also known as gradual, the global born or born glogal and the network theory. Regarding the measurement of internationalization, three indicators have been defined, these are time, scale and scope.
