What is the term used to describe an estimate an organization makes regarding its current employees and available external workers?

The term that describes an estimate an organization makes regarding its current employees and available external workers is "labor supply forecast." This concept involves predicting the future availability of labor in relation to the organization's needs, taking into account internal employee capabilities and the external labor market. Organizations perform labor supply forecasts to understand how many employees they will have available in the future, which helps in strategic workforce planning. It allows managers to identify potential gaps between supply and demand, informing hiring strategies, training initiatives, and talent development efforts.

Options like workforce analysis focus more on examining the current state and composition of the workforce rather than providing a prediction about future labor supply. Similarly, a labor supply assessment generally pertains to evaluating the current labor market conditions rather than forecasting future availability. An employee capacity review is likely more about evaluating the current productivity and performance of existing employees rather than estimating future labor sources.
