Final answer:
Managerial estimates are the most common method for estimating HR demand, typically involving top management decisions on employee needs and guiding the recruitment process.
Step-by-step explanation:
The most common method of estimating HR demand is through managerial estimates. This approach typically involves upper management making decisions about the number of employees needed within the organization.
This top-down approach can be seen in a scenario where an Executive Director (ED) of a human services agency seeks to understand the work environment through employee feedback but encounters managerial resistance.
Demand forecasting is the process of assessing and forecasting how many people are needed, their age structure, their professional structure, their educational level structure, their professional and technical poststructure, and their skill structure in the future.
Similarly, when a company has an open position, the HR manager directs the recruitment process, and upon gathering a list of qualified candidates, the department manager initiates the interview process to fill the position.
