Departments are basically the entities that are formed by large organizations to organize the work force and define reporting relationships. The departments are defined in a way that best aligns with the accomplishment of the institution’s goals.
Departments can be organized by functions such as human resources, marketing, administration, and sales. Or, a department can be organized in any way that makes sense for the customer, for example, ordering, sales, after sales service departments. Departments can also be organized by product or brand, generally the trend in multi-brand, multi-product companies.
