Which methods are used to forecast demand and supply in workforce planning?

• A. Trend analysis, scenario planning, ratio analysis, and skills inventories
• B. SWOT analysis, PEST analysis, and benchmarking
• C. Delphi method, brain-storming, and intuition
• D. Time series, regression, and cost-benefit analysis

Answer: (A)

Forecasting workforce needs hinges on methods that analyze trends, explore future scenarios, relate staffing to workload, and inventory current skills. Trend analysis uses historical data on both workforce and business activity to project future demand, identifying patterns, seasonality, and growth rates that inform how many people will be needed. Scenario planning goes beyond a single forecast by developing multiple plausible futures (such as rapid growth, steady state, or downturn) and testing how staffing should respond in each, which helps prepare for uncertainty. Ratio analysis establishes links between business output or service levels and staffing levels, enabling you to translate expected workload into required headcount under different conditions. Skills inventories map the capabilities, qualifications, and potential of the current workforce, revealing internal supply and gaps and guiding development, redeployment, or recruitment decisions. Together, these methods cover both sides of workforce planning—anticipating demand and assessing supply—so you can plan effectively.

Other approaches described tend to focus on environmental scanning, idea generation, or financial evaluation rather than directly producing actionable forecasts of workforce quantity and capability. While some quantitative tools can be helpful, they don’t provide the same integrated view of demand and supply that this combination offers.
