The Formal lines of authority from highest to lowest ranks are known as:

Scalar chain

The correct answer is Option (4) - Scalar chain.

Scalar Chain: An organisation consists of superiors and subordinates. The formal lines of authority from highest to lowest ranks are known as scalar chain. According to Fayol, “Organisations should have a chain of authority and communication that runs from top to bottom and should be followed by managers and the subordinates.” According to Fayol, this chain should not be violated in the normal course of formal communication. However, if there is an emergency then direct contact through ‘Gang Plank’.

Equity: Good sense and experience are needed to ensure fairness to all employees, who should be treated as fairly as possible,” according to Fayol. This principle emphasises kindliness and justice in the behaviour of managers towards workers. This will ensure loyalty and devotion. Fayol does not rule out use of force sometimes. Rather he says that lazy personnel should be dealt with sternly to send the message that everyone is equal in the eyes of the management. There should be no discrimination against anyone on account of sex, religion, language, caste, belief or nationality etc.

Order: According to Fayol, “People and materials must be in suitable places at appropriate time for maximum efficiency.” The principle of order states that ‘A place for everything (everyone) and everything (everyone) in its (her/his) place’. Essentially it means orderliness. If there is a fixed place for everything and it is present there, then there will be no hindrance in the activities of business/ factory. This will lead to increased productivity and efficiency.

Unity of Direction: All the units of an organisation should be moving towards the same objectives through coordinated and focussed efforts. Each group of activities having the same objective must have one head and one plan. This ensures unity of action and coordination. It prevent overlapping of activities.
