Answer:

Taylor’s scientific theory uses ‘data and human strengths’ for increasing output. The Bureaucratic management theory ‘focuses on hierarchies’ and tight job roles. On the other hand, the contingency theory suggests that the right style of management is dependent on the context of the situation.  

Explanation:

• To adopt any form of rigid or a single style is not effective in the long run. The contingency theory is an approach towards the management theory which focuses on the situation and the style of approach to be taken.  

• It is different from the other theories since it gives importance to the process of learning from certain specific situations.  

• These are used as ‘lessons to influence future management’ of the same or similar situations which is in contrast to Weber's bureaucracy and Taylor's scientific management theory.
