Hierarchy is a system of ranking individuals within an organization based on skill level, seniority, and commission paid. There may be multiple hierarchies within a single organization, and remuneration may be distributed through multiple levels of the chain of command.
Organizational hierarchies can also be used for security purposes, by excluding specific personnel from accessing software systems and data reports. Additionally, hierarchies can be used to show relationships between different entities, such as product categories and subcategories or customers in specific regions.
