Revise Variances for Cambridge 9609 (5.5.2)

Variance analysis is a fundamental management accounting tool used to monitor and control business operations. By comparing actual results against the budget, managers can identify areas where performance has deviated from the plan, allowing for timely investigation and corrective action.

Variance = Actual − Budget

Costs: F if actual < budget | A if actual > budget

Revenue: F if actual > budget | A if actual < budget

After identifying potential causes, management must decide on a response. The focus should be on 'material' or significant variances, as investigating every small deviation is not cost-effective. The response depends on whether the cause is controllable (e.g., staff inefficiency) or uncontrollable (e.g., a new competitor entering the market). Controllable issues require internal corrective action, while uncontrollable ones may necessitate a revision of the original budget.

Variance analysis can significantly influence employee behaviour. If used punitively to assign blame for adverse variances, it can lead to demotivation, dysfunctional behaviour like building slack into budgets, or even falsifying results. It's crucial for management to use variance reports constructively, focusing on learning and improvement rather than simply punishing underperformance. Furthermore, variances only highlight past performance and do not automatically provide solutions or predict future outcomes.
