Calculating variances is only the first step of variance analysis. To understand why they occurred and what they mean for your business, you need to consider the size and direction of the variance, the frequency and trend of the variance, and the cause and effect of the variance. A large or unfavorable variance may indicate a significant problem or opportunity that requires attention, while a small or favorable variance may not be as important or may be due to normal fluctuations or random factors. A consistent or recurring variance may suggest a systematic issue or a change in the business environment that needs to be addressed, whereas a one-time or isolated variance may not be as relevant or may be due to an exceptional event or a timing difference. Additionally, variances can have different causes, such as changes in market conditions, customer behavior, product mix, pricing, costs, quality, efficiency, or errors. Furthermore, they can also have different effects on profitability, cash flow, customer satisfaction, and competitive advantage. You should identify the root causes and consequences of the variances to determine whether they are controllable or uncontrollable and whether they are favorable or unfavorable in the long run.
