Disadvantage of manpower planning
In order to make projections regarding demand and supply, there is a need of description of characteristics of manpower which is not easy to define, classify and provide for so far most of the information available is on demographic aspect of labor force devised in terms of the definition of working age and sex distributions etc. but this is only a part of manpower planning. Large part of the subject, concerned with projections, cannot be done purely in demographic terms, rather the other qualities of labor such skill and training etc. will have to be considered also.
There is another set of problems are associated with the concept of employment of labor. There is no prices definitions and therefore criterion for classifying employable labor. The employability requires the fulfillment of certain physiological conditions, such as physical and mental capacity. Furthermore, it is also concerned with the aspect; whether who is able for work should also be willing to work. This may be related to the employability of a person with the market demand for him. If there is a demand for him, he is employable, otherwise not. Each one of these criteria is not sufficient in providing a permanent or fixed basis for collecting information on labor force.
