3.9.4 (HL)—Budgets in decision-making

Managers use budgets to allocate scarce resources, set targets and compare actual performance with an agreed plan. Variance analysis then shows where attention, training, reprioritisation or additional investment may be needed.

A department that repeatedly overspends may need a supplier review or process change; one that underspends may have spare capacity—or may be cutting maintenance and damaging quality. Decisions should connect the financial signal to operations, customers and strategy.

Budgets also coordinate departments: a marketing campaign can increase the sales budget while requiring extra production, staffing and working-capital finance. If demand changes suddenly, managers may need to revise the plan instead of protecting an obsolete target.

A budget is not a neutral measure of managerial worth. Targets can motivate, but unrealistic or short-term targets encourage gaming, rivalry or under-investment. Use the budget as evidence alongside context, non-financial indicators and the business’s longer-term aim.
