Answer:
1) Contingency theory
2) Classical management theory
Step-by-step explanation:
1) The contingency theory of management states that employees' efficiency depends on an interaction between management behaviors and specific working conditions. That is why one approach that best suits a group of employees may not work with the rest, and vice versa. So every group must be managed differently based on their specific working conditions.
2) The classical management theory advocates for specialization of labor, so a tasks that yields positive results should be imitated and carried on by the rest of the employees.
