How do organizations forecast and plan their future workforce needs?

"Forecasting an organization’s human resource needs, known as an HR demand forecast, is an essential aspect of HR planning. This process involves two forecasts: (1) determining the number of people needed by some future time (in one year, for example) and (2) estimating the number of people currently employed by the organization who will be available to fill various jobs at some future time; this is an internal supply forecast. The Advancement Planning process at Best Buy involved reducing the turnover that occurs in most retail environments. The company has achieved a second-place ranking, behind only Costco, and its general managers’ tenure at a store averages five years. The performance of managers at Best Buy is reviewed to identify people who can fill vacancies and be promoted, a process known as succession planning. If Best Buy has a temporary shortage of sales professionals, at the holiday shopping season, for example, they can hire an experienced contractor or interim executive as a temporary or contingent worker, someone who wants to work but not on a permanent, continuous basis."
