In hospitals, the following type of departmentation is common

The correct answer is D. all of these.

Departmentation is the process of grouping jobs into organizational units. In hospitals, there are many different types of departmentation, including by function, by committee, and by geographical region.

Departmentation by function is the most common type of departmentation in hospitals. This type of departmentation groups jobs together based on the function they perform. For example, there may be a department of nursing, a department of medicine, and a department of surgery.

Departmentation by committee is another common type of departmentation in hospitals. This type of departmentation groups jobs together based on the committee they are assigned to. For example, there may be a committee on quality assurance, a committee on patient care, and a committee on finance.

Departmentation by geographical region is less common than departmentation by function or by committee, but it is still used in some hospitals. This type of departmentation groups jobs together based on the geographical region they serve. For example, there may be a department that serves the city, a department that serves the suburbs, and a department that serves the rural areas.

Each type of departmentation has its own advantages and disadvantages. Departmentation by function is efficient because it allows employees to specialize in their area of expertise. However, it can be inflexible because it can be difficult to change the structure of the organization when new needs arise. Departmentation by committee is flexible because it allows for easy communication and collaboration between different departments. However, it can be inefficient because it can be difficult to reach consensus on decisions. Departmentation by geographical region is effective in meeting the needs of a diverse population. However, it can be expensive because it requires duplication of services.

The type of departmentation that is most appropriate for a particular hospital will depend on a number of factors, including the size of the hospital, the complexity of its services, and the needs of its patients.
