Manpower planning is important because it ensures that the right number of people are performing tasks to meet the objectives of the company. Without proper planning, it makes it difficult (if not impossible) to meet corporate objectives and targets.
Through workload and workforce analysis, a company can determine how many people they need to staff a particular task. This is common in the manufacturing industry. In addition, manpower planning includes a qualitative aspect in terms of the proficiency of the staff. It evaluates the skills of the person assigned to the job to ensure that they are able to perform efficiently, and can help with the completion of the overall company objectives in their position.
