Business
Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Sociology
Sociology is the scientific study of society, including patterns of social relationships, social interaction, and culture. It is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order, acceptance, and change or social evolution. Many sociologists aim to conduct research that may be applied directly to social policy and welfare, while others focus primarily on refining the theoretical understanding of social processes. Subject matter ranges from the micro-sociology level of individual agency and interaction to the macro level of systems and the social structure.
Business
I believe that leaders and leadership teams working together in a proper design will run the business more effectively than by hierarchical, command-and-control managing. But I can't prove that. And there are no models.
Marvin Bower (1966) The Will to Manage p. 7.
Management
Management as an activity has always existed to make people’s desires through organized effort. Management facilitates the efforts of people in organized groups and arises when people seek to cooperate to achieve goals.

Sociology
I often say that sociology is a martial art, a means of self-defense. Basically, you use it to defend yourself, without having the right to use it for unfair attacks.
