The term 'Level of Authority' refers to the hierarchical structure of an organization, which is typically divided into ranks and echelons. RANK is a four-letter word that is used to describe the position of an individual within an organization, while ECHELON is a seven-letter word that is used to describe the level of authority within an organization. Together, these two terms are used to describe the hierarchical structure of an organization, with each RANK having its own level of authority.
