You could have given a little more information such as whether you are a student or a professional, your designation, and the nature of the industry you work in, etc.
Factors Influencing Manpower Planning
Manpower planning depends on (a) capacity, (b) demand, and (c) skills of the people. However, this is a very broad categorization.
For example, in a restaurant, the number of chairs (number of covers in the hotelier's language) determines how many waiters you should have. The number of waiters determines the requirement of the captains.
In star hotels, the number of rooms determines the requirement of housemen, room service staff, etc.
However, both of the above examples also depend on the market demand.
Manpower Planning in Different Industries
In the courier and logistics industry, you need to maintain the manpower whether there is demand or not. For example, the number of deliveries made cannot be the sole criterion for deciding the number of couriers. This is because we have to take into account the traffic situation as well. In big cities, at certain places, commercial vehicles move at 5-10 KM/hour. Then the manpower depends on the volume of the load to be picked up as well. You need to have sufficient loaders depending on the load.
Therefore, there is no generalization, and manpower planning will differ from one industry to another, one product to another, one city to another, etc.
