1. Improvement of Labour Productivity:
Manpower or human resources as a factor of production differs from other factors of production. As it is subject to its free will, the productivity of labour can be improved if the workers are kept satisfied.
In other words, just as satisfied workers can be productive, dissatisfied workers can be destructive.
Therefore, through proper human resource planning we can improve the morale of the labour and improve labour productivity.

5. Control over Recruitment and Training Cost:
Highly skilled personnel are in short supply and it is very cos.tly to hire, train, and maintain them.
A company has to incur heavy costs in processing the applications, conducting written tests, interviews etc., and in the process of providing adequate training facilities.
In consideration of these costs, it is essential to plan carefully in relation to the manpower so as to reduce the recruitment and training cost.
6. Mobility of Labour:
Today, it is very difficult to maintain the qualified personnel in an organisation as they will be moving from one job to another in search of better prospects.
In a free society, human beings enjoy unrestricted mobility from one part of the country to the other.
Therefore, in order to reduce the loss of experienced and skilled labour, every organisation must have a sound system of manpower planning.
7. It cans Facilitate Expansion Programmes:
In these days of rapid industrial development, every company goes for expansion of its activities.
As a result of the increasing company size, the demand for human resources also increases. This necessitates proper manpower planning so as to ensure the continued supply of the required manpower for the firms’ activities.
8. To Treat the Manpower like Real Corporate Assets:
Today it is being increasingly felt by the practising managers and psychologists that men in an organisation must be treated like the most significant assets.
The productivity of a company can be improved only through manpower planning, recognizing the significance of the human factor in business.
Proper manpower planning considers the fact that satisfied workers can contribute a lot to the overall profitability of the firm through improved productivity.
