Explanation:

Human resources planning allows companies to plan ahead so they can maintain a steady supply of skilled employees. That's why it is also referred to as workforce planning. The process is also used to help companies evaluate their needs and to plan ahead to meet those needs.

Human resource planning needs to be flexible enough to meet short-term staffing challenges while adapting to changing conditions in the business environment over the longer term. HRP starts by assessing and auditing the current capacity of human resources.

The challenges to HRP include forces that are always changing such as employees getting sick, getting promoted or going on vacation. HRP ensures there is the best fit between workers and jobs, avoiding shortages and surpluses in the employee pool.
