Which technique measures the relationship between two data sets to optimize resource allocation?

• A. Trend Projection.
• B. Replacement Chart.
• C. Ratio Analysis.
• D. Succession Planning.

Answer: (C)

Understanding how two data sets relate to each other lets you see how changes in one area affect another, guiding how you allocate resources. Ratio analysis specifically quantifies the relationship between two variables, such as inputs and outputs or costs and capacity. In workforce planning, it helps you determine how many staff are needed for a given level of workload, or how costs per unit of output change as you adjust headcount or shift mix. By comparing these relationships, you can spot inefficiencies, forecast staffing needs, and adjust staffing, budgeting, or scheduling to keep operations balanced and cost-effective. Other techniques serve different purposes: trend projection uses past changes to forecast future values, while replacement charts and succession planning are about identifying and developing people for future roles, not directly about how two data sets relate to drive resource decisions.
