Question

exlain the factor on which productivity depends

Answer 1

Productivity depends on both the efficiency of men and machines deployed for production. It also depends on the uninterrupted supply of energy.
If suitable incentives are given to workers and if a high level of morale is maintained, production is definitely going to be higher than if such factors are not taken care of.
The management must generally link incentives to productivity in order to maintain high levels of production.
