What technique uses historical statistical mathematical ratios between business volume metrics (e.g., sales volume) and required employee headcounts to forecast labor demand?

Explanation

• Ratio Analysis calculates operational ratios (e.g., sales revenue generated per salesperson) to predict future staffing requirements as operational volume expands.
• Trend Analysis evaluates historical headcount changes over time.
• Delphi Technique relies on qualitative panel consensus rather than direct quantitative financial ratios.
