MOG B—Executive, Administrative, And Managerial Occupations

Managers make decisions and establish objectives for the department or establishment; they are generally not directly concerned with the fabrication of products or with the provision of services. They possess a knowledge of the day-to-day operation of the organization, but do not necessarily have the detailed knowledge required of a first line supervisor. Most Managers are classified in MOG B. Please see Section A of the OCSM for more information on Managers and Supervisors.

In the case of small establishments or departments, employees who plan, organize, direct, or control major functions, may also perform functions normally assigned to supervisors, such as supervising lower level employees. Consider such employees as managers.

There are also management related occupations in this MOG who implement the establishment functions in support of management at the operational level. Examples of these specialized functions are analyzing financial records and policies, reviewing organizational structures and methods, purchasing goods for internal organizational use, enforcing standards and regulations, etc.
